Installation requires skid removal then securing the enclosure to the supporting foundation. Remove the Shipping Skid Open the front door and remove the four lag screws (2 in front, 2 in rear) securing enclosure to the wood skid. Supporting Foundation The supporting foundation for the enclosure must be level and straight. Refer to the applicable enclosure outline drawing included with the Series 300 for all mounting details including door opening space. If bottom cable entry is used, the foundation must be prepared so that the conduit stubs are located correctly. Refer to the enclosure outline drawing for specified area and location. Provide cable bending spaceandclearancetolivemetalparts. Whena concrete floor is poured, use interlocking conduit spacer caps or a wood or metal template to maintain proper conduit alignment. Mounting Refer to the applicable enclosure outline drawing furnished with this switch and mount the Series 300 according to details and instructions shown on diagram. Line Connections Refer to the Wiring Diagram provided with your Series 300 ATS. All wiring must be made in accordance with the National Electrical Code and local codes. It is unnecessary to remove pole covers from the transfer switch. If you do remove them, reinstall them carefully. De–energize the conductors before making any line or auxiliary circuitry connections. Be sure that Normal and Emergency line connections are in proper phase rotation. Place engine generator starting control in the OFF position. Make sure engine generator is not in operation. Testing Power Conductors Do not connect the power conductors to the ASCO Series 300 transfer switch until they are tested. Installing power cables in conduit, cable troughs and ceiling-suspended hangers often requires considerable force. The pulling of cables can damage insulation and stretch or break the conductor’s strands. For this reason, after the cables are pulled into position, and before they are connected, they should be tested to verify that they are not defective or have been damaged during installation. NOTICE Protect the automatic transfer switch from construction grit and metal chips to prevent malfunction or shortened life of the ATS. Connecting Power Conductors After the power cables have been tested, connect them to the appropriate terminal lugs on the transfer switch as shown on the wiring diagram provided with this Series 300. Make sure the lugs provided are suitable for use with the cables being installed. Standard terminal lugs are solderless screw type and will accept thewiresizeslistedonthedrawingsprovidedwiththe Series 300. Be careful when stripping insulation from the cables; avoid nicking or ringing the conductor. Remove surface oxides from cables by cleaning with a wire brush. When aluminum cable is used, apply joint compound to conductors. Tighten cable lugs to the torque specified on rating label. Controller Ground A grounding wire must be connected to the controller’s lower left mounting stud. Because the controller is mounted on the enclosure door, a conductive strap must be used between the enclosure and the door. This connection provides proper grounding which does not rely upon the door hinges. Harnesses The transfer switch is connected to the left side of the controller by a plug–in harness (two plugs). terminal block for engine start and auxiliary circuit connections left side of transfer switch COMMON FEATURE 7 closes to start FEATURE 8 opens to start COMMON FEATURE 14B closed on emergency FEATURE 14A closed on normal COMMON FEATURE 14BA closed on emergency FEATURE 14AA closed on normal Engine Starting Signals 5amps,32VDC 5ampsresistive28VDC or 120 V AC max.

Transfer Test Both normal and emergency sources must be available and the emergency source generator (if used) must be capable of being started in this procedure. Perform steps 1 through 8 at the right. Observe the status lights. Black circle means light is on. White circle means light is off. NOTE:If Motor Load Transfer feature is activated, then transfer may not occur immediately after the respective time delays. Transfer will only occur when the phase relation- ship between sources is correct. This completes the Functional Test of the ASCO Series 300 Automatic Transfer Switch. Leave the engine–generator starting control in the automatic position. 1 The normal source must be available and the generator must be ready to start.

An under voltage condition on any phase of the normal source is de- tected by the sensor. When the normal source voltage fails or the Transfer Test button is pressed, the SE relay de-energizes and relay NR begins its timing cycle (1 or 3 seconds,momentary normal source outage delay). The NR relay is provided with a time delay on dropout to override momentary outages and prevent nuisance starting of the engine-driven generator. If the normal source voltage returns above the sensor dropout setting before the time delay expires, the NR relay timing cycle is reset to zero and relay SE energizes. If the normal source voltage does not return above the sensor dropout setting before the time delay expires, the NR relay de-energizes and signals the engine-driven gen- erator to start. At the same time, a voltage and frequen- cy sensor begins monitoring the emergency source. The sensor will accept the emergency source only when both voltage and frequency reach preset pickup points. Usual- ly about ten seconds elapse from dropout of the NR relay to acceptance by the sensor. This time span occurs be- cause the engine-driven generator must crank, start, and run up to nominal pickup points. For this reason, if the Transfer Test button is pressed it must be held for 15 sec- onds. If the emergency source is available immediately, the sensor may accept it as soon as NR relay drops out. When the emergency source is accepted by the sensor, relay ER begins its timing cycle (transfer to emergency delay). ER relay is provided with an adjustable (0 to 5 minutes) time delay on pickup to delay transfer of the load to the emergency source. For immediate transfer press Bypass Time Delay button. ER relay energizes, the TS coil is energized, the transfer switch operates, and all switch contacts (mains, controls, auxiliaries) reverse position. The transfer switch is now supplying the load from the emergency source. ThetransferswitchwillremainintheEmergency position until the normal source is restored. If the Transfer Test button is used, the transfer switch will remain on emergency until the retransfer to normal delay times out. Retransfer to Normal The sequence for load retransfer to the normal source automatically begins when the voltage sensor detects restoration of the normal source. The voltage level must rise above the preset pickup point on all phases before the sensor will accept the normal source. Whenthenormalsourceisacceptedbythesensor, relay SE begins its timing cycle (adjustable 1 sec. to 30 min.,retransfer to normal delay). For immediate retransfer press Bypass Time Delay button. SE relay is provided with a time delay on pickup to prevent immediate load retransfer to the normal source. The delay insures that the normal source has stabilized before reconnection of vital loads. If the normal source voltage falls below the present dropout point before the time delay expires, the timing cycle is reset to zero. If the emergency source fails for more than 4 seconds during the timing cycle, ER relay drops out and the load is immediately retransferred to the normal source, if that source is acceptable. SE relay energizes and ER relay is dropped out. The TS coil is energized, the transfer switch operates, and all switch contacts (mains, controls, auxiliaries) reverse position. The transfer switch is now supplying the load from the normal source again. Upon retransfer to the normal source, NR relay begins its timing cycle (unloaded running delay, engine cooldown). NR relay is provided with a 5 min. time delay on pickup to keep the engine running for a cool-down period. NR relay energizes after the time delay and signals the engine-driven generator to shut down. All circuits are reset for any future normal source failure.

For immediate retransfer press Bypass Time Delay button. 4.Unloaded Running (Engine Cooldown) Delay allows engine to run unloaded for 5 minutes. Checklist for Yearly Inspection Hazardous voltage capable of causing shock, burns, or death is used in this switch. Deenergize both Normal & Emergency power sources before performing inspections! Clean the enclosure.De–energize all sources, then brush and vacuum away any excessive dust accumulation. Remove moisture with a clean cloth. Check the transfer switch contacts. De-energize all sources, then remove the transfer switch barriers and check contact condition. Replace the contacts if they become pitted or worn excessively. Reinstall the barriers carefully. Maintain transfer switch lubrication.Under normal operating conditions no further lubricating is required. Renew factory lubrication if the switch is subjected to severe dust or abnormal operating conditions or if TS coil is replaced. Order lubricant kit 75–100. Check all cable connections & retighten them. Torquetovaluesshownontransferswitchlabel. Replacement parts.When ordering parts provide the Serial and Catalog Nos. from the transfer switch nameplate.

If the controller must be isolated, follow these steps carefully. Disconnecting the Plugs 1. Observe the position of the transfer switch. a. If the transfer switch is in the Normal position, place standby engine starting control in the off position. Then open the emergency source circuit breaker. b. If the transfer switch is in the Emergency position, open the normal source circuit breaker. Place the engine starting control in the test or run position. 2. Separate the quick disconnect plugs by squeezing the latches. Do not pull on the harness wires. 3. Label, remove, and tape the signal wires connected to the engine start terminals on the transfer switch: TB1 and TB3, or TB1 and TB2. Reconnecting the Plugs 1. Observe the position of the transfer switch. a. If the transfer switch is in the Normal position, be sure that the standby engine starting control is still in the off position. The emergency source circuit breaker still should be open. b. If the transfer switch is in the Emergency position, normal source circuit breaker still should be open. 2. Reconnect the signal wires connected to the appropriate engine start terminals on the transfer switch. See Section 1,Engine Starting Contacts. 3. The harness plugs and sockets are keyed. Carefully align the plugs with the sockets and press straight in until both latches click. 4. Restore the opposite source as follows: a. If the transfer switch is in the Normal position, place the standby engine starting control in the automatic position. Then close the emergency source circuit breaker. b. If the transfer switch is in the Emergency position, close the normal source circuit breaker. The load will be automatically retransferred to the normal source after the Retransfer to Normal Delay.For immediate retransfer, press Bypass Time Delay button. Place the engine starting control in the automatic position. TESTING & SERVICE (continued) 3 --- 2 MANUAL LOAD TRANSFER This procedure will manually transfer the load if the controller is disconnected.

If Motor Load Transfer is active, wait for in- phase condition (see below). — Voltmeter should read at least 90% of nominal phase to phase voltage between transfer switch terminals NB and NC, NC and NA, and NA and NB (or NL1 and NL2 for 2 pole switches). Gen-Set does not stop after load retransfer to the normal source. Wait for the 5 minute Unloaded Running Delay to time out. Starting control must be in automatic position.— Trouble-Shooting the Motor Load Transfer Feature (refer to page 5–4) Use extreme caution when using a meter to measure voltages in the following steps. Do not touch power terminals; shock, burns, or death could result ! 1. Connect a voltmeter (set for twice system phase–to–phase voltage) between Transfer Switch terminals NA and EA. 2. Manually start generator. Voltmeter needle should sweep back and forth at a regular rate between 0 and about twice system voltage. 3. Press and hold Transfer Test button. The load should transfer to emergency source when meter needle is near 0 volts. If transfer does not occur, Motor Load Transfer feature is not operating. 4. Release the Transfer Test button. The load should retransfer back to the normal source after the Retransfer to Normal Delay,ifused. Theretransfer should occur when the needle is near 0 volts. If retransfer does not occur after the time delay, the Motor Load Transfer feature is not operating. 5. For immediate retransfer, press the Bypass Time Delay button. Then disconnect the voltmeter. If the problem is isolated to circuits on the controller or the transfer switch, call your local ASCO Power Technologies sales office, representative, or ASI. In the United States, call 1–800–800–2726. Furnish the Serial No., Bill of Material (BOM) No., and Catalog No. from transfer switch nameplate.

SECTION 5 CONTROL FEATURES – ENGINE EXERCISERS 5 --- 1 These timers periodically exercise the emergency engine-generator plant. They can be set to exercise with or without load transfer, or they can be completely disabled. The engine-generator should be exercised under load once a week for a minimum time period of 20 minutes, or follow the recommendations of the engine-generator set manufacturer. Refer to page 4–2 for location of DIP switches, battery (provided), and jumper block in the controller. BUILT–IN ENGINE EXERCISER The engine exerciser included in ASCO Series 300 Automatic Transfer Switches provides a once a week 20–minute exercise period. It occurs immediately when the Set Engine Exerciser push button is pressed (and held for at least 5 seconds), and then at the same time weekly thereafter. A 9 volt alkaline battery (Duracell MN1604,Everready 522, or Panasonic 6AM6) is furnished and installed in the controller to maintain the setting. The battery jumper block must be shifted to the ON position. See Figure 4–2 on page 4–2. Fillindayandtimeset. Week Day______ Time_______. DIP Switch Settings FUNCTION S1 DIP SWITCH S2 DIP SWITCH Std.

This microprocessor-based controller includes a user interface. All monitoring and control functions can be done with the enclosure door closed for convenience and safety. Voltage pickup and dropout settings and time delay settings can be made through a system of menus. Control Overview The user interface includes a graphic display, control buttons, and indicator lights. Five buttons allow access to all monitoring, control, and settings functions. Six lights show status indication of source acceptability, transfer switch position, and alerts. The screens are arranged in three levels. Access to some screens require entering a password (indicated by a closed padlock symbol). Up-down arrows buttons The up and down arrow buttons are used to navigate the settings. These buttons also increase and decrease a value to modify a parameter while in the settings level screens. Enter/save settings button (see page 9 for Are you sure? screen) The enter/save settings button moves from the status level to the Main Menu level and other levels. It also is used to select a parameter and to enter or save a new setting. Escape button (see page 9 for Are you sure? screen) The escape button ignores a change and returns to the previous status level. Transfer button (see page 9 for Are you sure? screen) The transfer button has several functions. Refer to the control message (bottom line) on the control status / home screen. A closed padlock symbol indicates that a password must be entered (see page 9). • transfer test function simulates a failure of the normal source. • for a 3NTS and 3NDTS, press this button to transfer or retransfer the load. • bypass timer function cancels an active time delay • abort function cancels a pending operation (inphase transfer, for example) Four transfer switch status lights (light is on when:) • Normal source accepted (left light) • Emergency source accepted (right light) • Load on normal [transfer switch in normal position] • Load on emergency [transfer switch in emergency position] Alert light (light is on when:) Read the display for more information. • Any alarm condition turns on this light. Not in automatic light (light is on when:) • Not in automatic mode (manual); blinking indicates transfer inhibit. For 3NTS and 3NDTS this light is always on, indicating that it is a manual transfer switch. If Feature 6DL is active, the light is on when the load is transferred to emergency. User Interface message lines for control status control message Load on Normal Load on Emergency Normal Source Accepted Emergency Source Accepted See pages 20, 21, 22 Group G Controller Users Guide 381333-400 H 3 Status Information The controller provides the status of both power sources (normal and emergency) and the position of the transfer switch. Press the up and down arrow buttons. No password is required to navigate through these screens. ATS Status Screen The ATS status is the home screen. It shows the present status of the ATS including: transfer sequence status, and running timers, status of connected source, and position of ATS. A control message appears below the status messages. The control message instructs the user on what action is available. All other screens automatically return to the ATS Status screen (home screen) after five minutes of inactivity. Metering Screen One of several metering screens is provided (a factory setting). It shows the rms voltage and frequency readings of the power sources. If enabled, the voltage unbalance will also be displayed. If the current sensing option is provided, the load current is also displayed. Alarm Screen Active alarm message appear or no active alarms. A control message appears below the alarm message. If an active alarm must be acknowledged, the screen stays on until you press enter. Some alarms are self clearing. Controller Screen Controller information, name, location, present date and time appears. If an optional software key (dongle) is plugged into the controller, a key symbol is shown in upper right corner of this screen. Accessory 11BE is described on page 31. Source Acceptability (Feature 1C time delay is described on page 11.) The controller considers a source unacceptable if any of these conditions are true: Any phase voltage of the source is less than the voltage dropout setting for more than the Feature 1C setting. Any phase voltage is greater than voltage trip setting for more than 3 seconds. Frequency of the source is less than the frequency dropout setting for more than Feature 1C setting. Frequency is greater than over-frequency trip setting for more than 3 seconds. The phase unbalance is greater than the unbalance dropout setting (only if enabled and 3 phase system). The phase rotation of the source does not match the reference phase rotation. (only if enabled and on 3 phase system). The controller considers a source acceptable again when all these conditions are true: Each phase voltage is greater than the voltage pickup setting. Each phase voltage is less than over-voltage trip setting by more than 2% of nominal. The frequency of the source is greater than the frequency pickup setting. Frequency is less than the over-frequency trip setting by more than 2% of nominal. The phase unbalance is less than the unbalance pickup setting (only if enabled and 3 phase system). The phase rotation of the source matches the reference phase rotation.

Normal Source Failure. The Normal source is considered unacceptable when any one of four voltage or frequency conditions occur (see page 3). Transfer Test Signal. The test transfer signal can be from the transfer button, the engine-generator exerciser, or via the optional serial port (Accessory 11BE). The controller begins the load transfer sequence by de-energizing the SE relay and starting the Feature 1C time delay. Feature 1C time delay on engine starting prevents nuisance starting of the engine-generator set and load transfer to emergency due to momentary failures of the normal source. If the normal source is restored (voltage returns above the dropout point) while Feature 1C time delay is running, the SE relay is re-energized and the transfer sequence is terminated. (For transfer test the Feature 1C time delay is bypassed.) Engine Start Signal. When the Feature 1C time delay ends, the controller de-energizes the NR relay which signals the engine-generator to start. The controller monitors the emergency source, waiting for it to become acceptable. Usually about 10 seconds elapse from dropout of the NR relay to acceptance of the emergency source. This interval occurs because the engine-generator must crank, start, and run up to nominal pickup points. If the emergency source is available immediately, the controller will accept it as soon as the NR relay drops out. When the emergency source becomes acceptable, the controller starts the Feature 2B time delay on transfer to emergency (if desired). Feature 2B time delay allows the emergency source to stabilize before load transfer. If the emergency source fails while Feature 2B time delay is running, the controller again waits for the emergency source to become acceptable again and restarts Feature 2B. At the conclusion of the Feature 2B time delay, the controller is ready to transfer the load to emergency. If enabled, Feature 31F time delay will run prior to transfer and the Feature 31 output will be active while the time delay runs. Also, if the inphase transfer feature (for motor loads) is enabled, the controller will inhibit transfer until the sources are inphase. Load Transfer. To transfer the load to the emergency source the controller energizes ER relay. The transfer switch TS coil energizes, and all transfer switch contacts (mains, controls, auxiliaries) reverse position. Transfer switch is now supplying the load from emergency source. Feature 1F time delay ignores a momentary voltage drop of the emergency source when load is added to the generator. If enabled, Feature 31M time delay will run after the transfer and the Feature 31 output will be active while the time delay runs. - Normal Failure - Transfer Test - Gen exercise (with load transfer) SE relay deenergizes Feature 1C time delay NR relay deenergizes. Generator start signal Emergency accepted Feature 2B time delay Feature 31F time delay Inphase transfer feature (if transfer test or gen exercise) ER relay energizes TS coil energizes. Load transfer to emergency Users Guide Group G Controller 24 381333-400 H Open-Transition Automatic Transfer (3ATS) continued Load Retransfer to Normal The sequence for load retransfer to the normal source begins automatically when the controller detects a restored normal source, a cancelled transfer test signal (local or remote), a cancelled remote transfer to emergency signal, or a completed generator exercise (with load transfer). Normal Source Restoration. The Normal source is considered acceptable again when all four voltage and frequency conditions occur (see page 3). Cancel Transfer Test. Removal of the test transfer signal can be by pressing the transfer button again, ending a remote test, complete engine-generator exercise period, or via the optional serial port (Accessory 11BE). The controller begins the load retransfer sequence by starting the Feature 3A time delay. Feature 3A time delay on retransfer to normal allows the normal source to stabilize. If the normal source fails while the Feature 3A time delay is running, the controller waits for the normal source again to become acceptable and restarts the Feature 3A time delay. If the emergency source fails while Feature 3A is running, the controller bypasses the time delay for immediate load transfer. To bypass Feature 3A time delay press the transfer button (bypass timer). At the conclusion of the Feature 3A time delay, the controller is ready to transfer the load to normal. If enabled, Feature 31G time delay will run prior to retransfer and the Feature 31 output will be active while the time delay runs. Also, if the inphase transfer feature is enabled, the controller will prevent transfer until the sources are inphase. Load Retransfer. To retransfer the load to the normal source the controller de-energizes ER relay and energizes SE relay. The transfer switch TS coil energizes, and all transfer switch contacts (mains, controls, auxiliaries) reverse position. The transfer switch is now supplying the load from the normal source again. Engine Cooldown and Stop. After load retransfer to the normal source, the controller starts Feature 2E time delay. Feature 2E time delay provides an unloaded cooldown running period for the engine-generator. At the end of the time delay, the controller energizes the NR relay and the engine-generator is signaled to shutdown. - Normal restored - Cancelled Test - Gen exercise completed Feature 3A time delay Feature 31G time delay Inphase transfer feature ER relay energizes SE relay energizes TS coil energizes.

If enabled, Feature 31F time delay will run prior to transfer and the Feature 31 output will be active while the time delay runs. Load Transfer. To transfer the load to the emergency source in a delayed-transition mode the controller energizes the ER relays. The transfer switch CN coil energizes and opens the CN transfer switch main contacts. The load is disconnected from both sources. The load disconnect time delay starts. When this time delay ends, the controller energizes the ER relays. The transfer switch CE coil energizes and closes the CE transfer switch main contacts. Transfer switch is now supplying the load from emergency source.

They can be factory installed or most can be ordered later as an accessory kit. Deenergize both Normal and Emergency power sources before installing an accessory kit. Advanced Function Software Bundle (Accessory 11BE or Kit 935147) If optional Accessory 11BE software was ordered, the controller is factory configured with additional functions: communication, programmable exerciser, event log, common alarm output contact option OP1 (in the controller). On three pole switches the following additional functions are also enabled: three phase emergency sensing, emergency source unbalance, and phase rotation sensing. The controller has additional screens for these functions. Communication. Under the General settings, a screen allows the user to configure Communication (RS485 port). The baud rate can be set off, 9600 – 115200. The address can be set 1 to 247. See the Appendix for setting DIP switches S7 and S8. S7 sets the terminating resistor; S8 sets 2 wire or 4 wire. See pages 4 and 13. Programmable Exerciser. Under the Engine Exerciser settings, a screen allows the user to configure the optional exerciser. This exerciser provides seven programmable exercise periods. They can be set for once a week (all), alternate weeks (1st, 2nd, 3rd, 4th, 5th week), and each with an adjustable start and exercise period. See pages 4, 17 and 18. Event Log. Under the Event Log main menu, a screen allows the user to view events. Use the up and down keys to navigate the event list (last 300 events). See pages 4, 19, 35 (Appendix event types), and 36 (Appendix event causes). Engine/Common Alarm Input* The Engine/Common Alarm Input is used to connect an external alarm signal from separate equipment to the Transfer Switch controller. This status is visible via screen, alert LED, communications, and will also be logged as an event. Refer to the wiring diagram provided with the transfer switch for connection and rating details. If allowable this setting can be enabled under the Common Alarms section of the General Settings. *This physical input is shared with the load shed (Acc 30) functionality and as a result only one of these can be used at a time and they cannot be used simultaneously. Common Alarm Output. Under the General settings, a screen allows the user to configure Common Alarms. The Output OP1 contact (in the controller) can be configured to operate when a common alarm occurs. Refer to the wiring diagram provided with the transfer switch for connections and rating of the OP1 contact. See pages 5, 15, 16 and 17 for settings (Settings, Features). 3 Phase Emergency Sensing On controllers configured for 3 phase the 11BE will enable the controller to display all three line to line voltages for the emergency source on the screen. Phase Rotation Monitor Under the Features menu the 11BE will allow for 3 phase switches to enable the phase rotation monitor. This feature will allow the user to select between an ABC or CBA phase rotation and will not consider a source acceptable unless unless it matches the selected rotation orientation. Emergency Source Unbalance Under the features menu the user will be allowed to enable emergency source unbalance for 3 phase switches with 11BE. When enabled the emergency source will not be considered acceptable if if the line to line voltages are unbalanced beyond the user configured unbalance drop 3 Phase Emergency Sensing On controllers configured for 3 phase the 11BE will enable the controller to display all three line to line voltages for the emergency source on the screen. Emergency Source Unbalance Under the features menu the user will be allowed to enable emergency source unbalance for 3 phase switches with 11BE. When enabled the emergency source will not be considered acceptable if the line to line voltages are unbalanced beyond the user configured unbalance dropout. Users Guide Group G Controller 32 381333-400 H 5140 Quad-Ethernet Module (Accessory 72EE or Kit 948551) This accessory provides a 10/100 Mbit Ethernet interface to the transfer switch. It includes embedded web pages and access to Modbus registers for monitoring and control. It is mounted on a DIN rail. Current Sensing Module (Accessory 23GA – 1 phase, 23GB – 3 phase, or Kit 935150) This accessory is a current sensing module that is mounted on the controller (lower part). The customer-supplied current transformer(s) attach to the load cables of the transfer switch. With this accessory installed the controller measures and displays the load current (1 phase, 3 phase, or off). This accessory is not available when a Power Meter is provided. See pages 4, 13 and 14 for settings (Other Parameters). Never leave an open secondary circuit of a current transformer. Dangerous voltage can cause shocks, burns, and/or death. When disconnected always install a shorting jumper between the current transformer terminals. Relay Expansion Module (Included on 3ADTS & 3NDTS) (Optional Accessory 18RX for 3ATS & 3NTS or Kit 935148) This accessory consists of a relay module mounted on a DIN rail. The module interfaces with the controller for dual-operator transfer switches (3ADTS & 3NDTS). It also provides some commonly used accessory relays (18B, 18G, etc.). Output OP2 and OP3 contacts can be configured for common alarms. See pages 4, 15 and 16 for settings (Features, Output OP1, OP2, OP3). Refer to transfer switch wiring diagram for connections and rating of OP2 and OP3 contacts. Uninterruptable Power Supply Module (Accessory 1UP or Kit 935149) This accessory consists of a module that attaches on a DIN rail. The module provides limited reserve power (approximately 3 minutes) to the controller and some accessories during a power outage until the generator starts. The built-in battery recharges when power is restored. Load Shed (from emergency source) (Accessory 30AA and 30BA on 3ATS or 3ADTS only, kit not available) If optional Accessory 30AA or 30BA was ordered, the controller is factory configured for Load Shed. The home / control status screen displays the load shed operation. Load shed can be set to occur only when the sources are inphase (see pages 15 and 16). Refer to the wiring diagram provided with the transfer switch for connections to these accessories. Accessory 30AA is a load shedding circuit initiated by opening of a customer-supplied contact. Accessory 30BA* is a load shedding circuit initiated by removal of customer-supplied voltage (*specify voltage). Group G Controller Users Guide 381333-400 H 33 Hazardous voltage capable of causing shock, burns, or death is used in this switch. Deenergize both Normal and Emergency power sources before making any changes. Do not make any setting changes while the controller is energized. Any change in these settings may affect the normal operation of the transfer switch. This change could allow the load circuits to remain connected to low voltage source.
