Mounting the ELTS cabinetMount the ELTS on a load-bearing wall, in a location where it will not be subject to tampering or vandalism. If possible, install the ELTS where it is most secure from damage by a fire, flood or other incident likely to require its use. Do not install the ELTS inside any other electrical enclosure.

Physical requirements for mountingYou must mount either size ELTS cabinet with sufficient front clearance (30 inches) to allow the door to open completely.

Figure 5: ELTS cabinet mounting dimensionsNote: When planning your installation, make sure to leave space around the

cabinet for entry and exit wire conduit. Emergency line and neutral conduit may require extra space due to increased bend radius requirements for larger cables.

Planning wire entry into the ELTS cabinetThe Emergency power connections must enter the cabinet from the top or side of the cabinet within six inches of the top left corner.

Control, Normal power sensing and options wires connect most easily if they enter above the Remote station terminal or just below the Emergency sensing terminal on the left side of the cabinet.

Note: Do not run the control, normal power sensing and options wiring in the same conduit as Emergency phase or load power wiring.

Load wires in from the dimmer rack and out to the lighting loads connect most easily if they enter through the bottom of the cabinet either between or beside the transfer switch assemblies.

Note: Except for the emergency power supply wires, which must enter near the top left corner of the cabinet, recommended conduit entry locations may be changed based on your installation requirements.

Mounting the cabinetAfter determining where you want to install the cabinet, follow these instructions.

1. Install two 3/8" bolts 24.25 inches apart for the lower two support slots (the installer must supply the mounting hardware).

2. Use the mounting dimensions from Figure 5: ELTS cabinet mounting dimensions on page 9 to drill the holes for the upper two 3/8” bolts.

3. Place the ELTS cabinet on the wall supported by the two lower bolts.

Caution ELTS cabinets are very heavy. Make sure you have adequate equipment (or help) to lift the cabinet into place and support it while you secure the top two bolts.

4. Secure the ELTS to the wall with the two upper 3/8" bolts.

Installing Remote stations (optional)1. Install a standard two gang backbox (4" x 4" x 3.5") and run conduit from it

to the ELTS cabinet.

2. Pull five conductor, Class 2 (12 Vdc) wiring through from the backbox to the cabinet.

3. Connect the wires to the terminal strip on the back of the remote station. Make a note of each wire’s terminal assignment.

Figure 7: Remote station terminal connections4. Install the Remote station onto the backbox with four 6 - 32 x 1/2” oval

head machine screws (provided).

5. To install multiple Remote stations, repeat steps 1 – 4, wiring in parallel between Remote station terminal blocks.

Note: To avoid confusion, use the same wire terminal assignment at each Remote station you install.

Refer to Connecting Remote stations to the ELTS on page 17 for instructions for connecting Remote station wiring inside the ELTS cabinet.

Connecting power and control wiring to the ELTS cabinetWarning! To prevent death or injury due to electrical shock, Normal and

Emergency power to the ELTS must be turned off any time you are connecting or servicing any ELTS.

Connecting Emergency power (standard systems)Note: Standard ELTS systems connect Emergency power to phase lugs and

distribute it through pre-wired overload protection circuitry. Discrete systems do not have Emergency power lugs. Go to Connecting Emergency power (Discrete systems) on page 13 for instructions.

The Emergency power lugs are in the upper left of the ELTS cabinet. The ELTS is available in one or three phase power configurations.

1. Cut a hole within six inches of the top left corner of the ELTS cabinet

Note: Top conduit connections are recommended to reduce the cable bending necessary to connect to the lugs.

2. Install conduit and pull the Emergency power cables into the cabinet.

3. Using Figure 9, below, connect phase power cable to the correct lug:

▼ Three phase power cables connect to lugs A, B, and C

▼ Single phase power cables connect to lugs A and BNote: You cannot connect an ELTS designed for three phase operation to

single phase power or a single phase ELTS to a three phase source.4. Connect the Neutral cable to the Neutral lug.

5. Connect the Ground cable to the Ground lug.

Figure 9: Connecting Emergency power to the ELTSTable 1: Emergency power lug wire sizes and connection torques

6. Go to Connecting lighting circuit wires to transfer switches on page 14 for instructions on connecting lighting load wires.

Connecting Emergency power (Discrete systems)A Discrete ELTS does not have Emergency power lugs. Instead, Discrete systems wire emergency feeds directly to transfer switch Emergency inputs. Transfer switch assemblies connect either 20 amp circuits (up to six), or 50 amp circuits (up to two).

Note: Discrete ELTS systems require external distribution and overload protection circuitry.

1. Attach the conduit for the wires from the dimmer rack to the bottom of the ELTS cabinet (recommended.)

2. Pull Emergency feed Line and Neutral wires to the Emergency feed terminals on the right side of the transfer switches. See Figure 10, left, to match switch assembly load assignments.

3. Connect the Ground lug in the upper left corner to building Ground with a 14AWG to 2/0 wire and torque it to 50 in/lbs.

4. Connect Emergency feed Neutral wires to the EN-labeled terminals.

▼ 20 amp switches – connect Neutral wires to EN1 through EN6

▼ 50 amp switches – connect Neutral wires to EN1 and EN2

5. Connect Emergency feed Line wires to the EL-labeled terminals.

▼ 20 amp switches – connect Neutral wires to EL1 through EL6

▼ 20 amp switches – connect Neutral wires to EL1 and EL2

6. Repeat steps 2 and 3 for the other transfer switch assemblies.

TestingBefore you power up for the first time

Checking transfer switch operation manually By checking transfer switch manual operation before you apply power, you reduce the possibility of failure caused by mechanically frozen, damaged or obstructed switches. Each switch should rotate without catching or binding.

Warning! Normal and Emergency power should be off when you open the ELTS cabinet to check switch operation. Opening the cabinet with power applied may result in death or injury from electrical shock.

1. Open the ELTS cabinet.

Warning! Rotating the transfer switch assemblies manually with Normal or Emergency power applied may result in the assemblies switching automatically, causing severe hand injuries.

2. Turn the manual operation handle 90° clockwise. E (Emergency) should be visible on the assembly about 1.5 inches above the handle.

3. Rotate the handle 180° counter-clockwise. N (normal) should be visible.

Note: If you have difficulty operating the switch, check for installation debris that may be blocking switch operation.

4. Repeat steps 2 and 3 with the remaining transfer switch assemblies.

Turn on systemVoltage checkout1. Apply power to the ELTS and connected dimmer rack at the main circuit

breaker. The green Normal LED lights.

2. Apply emergency power. The red Emergency light turns on.

Warning! ELTS voltage tests should only be performed by qualified personnel using extreme caution. Opening the cabinet with power applied exposes you to death or injury from electrical shock.


4. Use a digital voltmeter (DVM) to test the feed voltage at the Normal power sensing terminal block (Figure 16 on page 16 for location). Phase A is on terminal 1, phase B on terminal 3 and phase C on terminal 5. Voltage must be within ±10 percent of the rated voltage for the ELTS.

5. Use the DVM to test the feed voltage at the Emergency power lugs. Phase lugs are labeled either A, B or C. Voltage values must be within ±10 percent of the rated voltage for the ELTS.

6. Close the ELTS cabinet.


Functional checkoutAfter verifying the Normal and Emergency voltages, check the ELTS system functions.

Figure 20: Local control operation and LED indications

Switch function1. Insert the key into the keyswitch on the front panel of the ELTS.

2. Turn the key to EMERGENCY POWER. The red light above EMERGENCYOPERATION turns on and the emergency loads go to full brightness. If Emergency power is provided by an engine/generator, there will be a short delay as the generator turns on and the voltage and frequency stabilize.

3. Release the key. The keyswitch returns to AUTO (center) and the EMERGENCY OPERATION light remains on.

4. Turn the key to the NORMAL POWER position. The green light below NORMAL OPERATION turns on if the system is functioning correctly.

5. Release the key. The keyswitch returns to AUTO and the NORMALOPERATION light remains on.

Remote switch functionsAfter confirming correct function of the keyswitch on the front of the ELTS cabinet, repeat the switch function checkout procedure at every remote station installed on your system.

Automatic functionThe automatic function tests the ELTS’s ability to switch back and forth from Normal to Emergency when Normal power is interrupted or restored.

1. Make sure the NORMAL OPERATION LED is lit on the ELTS front panel.

2. Turn off Normal power to the dimmer rack connected to the ELTS.

▼ The NORMAL OPERATION and NORMAL POWER STABLE LEDson the ELTS front panel go out

▼ The ELTS switches to Emergency power (the EMERGENCYOPERATION and EMERGENCY POWER STABLE LEDs light, and the emergency loads go to full brightness)

▼ If Emergency power is provided by an engine/generator, there will be a short delay before switching as the generator turns on and the voltage and frequency stabilize

3. Restore Normal power.

▼ The ELTS switches back to Normal power after the retransfer delay times out (the default setting is thirty minutes)

▼ On the front of the ELTS, the EMERGENCY OPERATION and EMERGENCY POWER STABLE LEDs turn off and the NORMALOPERATION and NORMAL POWER STABLE LEDs light

▼ If used, the Emergency power engine/generator turns off when the cool down time is complete.

Options functionELTS systems can also be activated by fire alarm and auxiliary circuits. Both are operated by a normally closed circuit controlled by the fire alarm or auxiliary relays. When the fire alarm or auxiliary circuit activates, the relay opens, causing the ELTS to switch to Emergency power. To test option relay function, either:

1. Activate the fire alarm or auxiliary relay.

▼ The ELTS should switch to Emergency power and the emergency loads should go to full

2. If you do not wish to activate the fire alarm or auxiliary circuit, generate an open circuit at the ELTS connection to the fire alarm or auxiliary circuit by disconnecting one of the two wires to the ELTS cabinet.

▼ The ELTS will switch to Emergency power and the emergency loads should go to full

Note: The second method tests the ELTS response to an open circuit, but does not confirm the fire alarm or auxiliary relay’s ability to open the circuit to the ELTS.


ELTS Timing, Voltage, and Line settingsFactory settings for timing, source voltage, and line frequency work best for most installations. If necessary, you can adjust settings after installation.

Warning! Improper setting changes may affect normal operation of the ELTS and result in switching function failure. Only make changes to timing, voltage, and frequency settings if you are familiar with the system.

Changing the Normal source outage delayThe Normal source outage delay is the amount of time the ELTS will tolerate a Normal power voltage fault before starting the switch to Emergency power. It can be set to 1 or 3 seconds using DIP switch S3-1.

1. Locate S3 using Figure 23 on page 23 and set S3-1 to the desired setting.

Changing the Transfer to Emergency and Return to Normal delaysThe Transfer to Emergency delay is the time the ELTS waits before switching to Emergency after the Emergency power voltage and frequency stabilize. You can set the delay from zero to five minutes, using potentiometer P2.

The Return to Normal delay is the time the ELTS waits before switching from Emergency to Normal after Normal power is stabilized. The delay can be set from one second to 30 minutes using potentiometer P1.

Note: To quickly restart an interrupted performance or for testing purposes, you can instantly switch the ELTS back to Normal power with the front panel Local switch or a Remote keyswitch station.

1. Locate potentiometer P1 (Emergency to Normal) or P2 (Normal to Emergency) using Figure 23 on page 23.

2. Turn the potentiometer clockwise to increase the interval or counterclockwise to decrease it. Use the adjustment values marked on the PCB to approximate the desired delay.

Note: Markings are approximate – you may need to test settings with a timing device to achieve exact delay values.

Figure 25: P2 (Transfer to Emergency) and P1 (Return to Normal)

Override Emergency source outage delayThe Override Emergency source outage delay is the time the ELTS will tolerate an Emergency power fault before starting the switching back to Normal power. It is set at the factory to four seconds and cannot be adjusted.

Generator cool down intervalThe Generator cool down interval is the time the ELTS waits before shutting off the Emergency power generator after switching back to Normal power. It is set at the factory to five minutes and cannot be adjusted.

Warning! Trouble shooting usually involves opening the ELTS cabinet and metering voltages. Opening the ELTS cabinet with power applied exposes you to death or injury from electrical shock. Use extreme caution during all troubleshooting activities.

Emergency or Normal Power Stable LED does not turn on properlyDuring normal operation, either the Normal Power Stable or Emergency Power Stable LED should be lighted. If one or the other does not light, the problem may be with the LED, Normal or Emergency sensing wiring, or Normal or Emergency power.

1. Switch between Normal and Emergency power on the ELTS control panel keyswitch and observe the results:

▼ The ELTS switches between Normal and Emergency1. Check for loose LED wire connections or defective LEDs.

2. Make sure the Control Panel connector is properly seated.

▼ The ELTS does not switch between Normal and Emergency. 1. Go to the next ELTS troubleshooting section.

The ELTS will not switch between Normal and EmergencyIf the system will not switch from Emergency power1. Check for tripped Normal power sensing wire circuit breakers.

2. If the circuit breakers are not tripped, meter Normal power using the procedures in Voltage checkout on page 19.

If the system will not switch from Normal power1. Meter Emergency power using the procedures in Voltage checkout on

page 19.

2. If no fire alarm or auxiliary circuits are connected to the ELTS, make sure the terminal jumpers are in place.

3. If fire alarm or auxiliary circuits are connected, meter between the wires to be certain the circuit is closed. An open circuit switches the ELTS to Emergency power.

If the system does not seem to function in either Normal or Emergency power mode1. Make sure the control panel connector is properly seated.

2. Check other wire connections for loose terminals or broken wires.

3. Use the procedures in Checking transfer switch operation manually on page 19 to test the switching mechanism for mechanical problems.


Remote stations cannot switch the ELTS 1. Switch between Normal and Emergency power on the ELTS control panel

keyswitch and observe the results.

If the ELTS does not switch locallyFollow the instructions in The ELTS will not switch between Normal and Emergency on page 31.

If the ELTS switches locallyTry switching the ELTS from other Remote stations, if multiple stations have been installed

1. If the other stations function, check the wire terminal connections on the problem station. See Installing Remote stations (optional) on page 11 for station connection requirements.

2. If the other stations do not function, or there is only one Remote station installed.

3. Check the wire connections on the Remote station terminal block.

4. Check the Remote station fuse in the ELTS cabinet

Figure 31: Locating the Remote station fuse5. Inspect the wiring between the ELTS cabinet and the stations for defects.

See Connecting Remote stations to the ELTS on page 17 for ELTS connection requirements.

Some ELTS circuits do not switch when the system changes sourcesPartial switching of ELTS circuits indicates one or more transfer switch assemblies, or the wiring to them, is defective.

1. Use the procedures in Checking transfer switch operation manually on page 19 to locate any transfer switch assemblies that have not switched and to manually test their function.

2. If an assembly cannot be switched manually, check for something that could be physically obstructing it. If you find something, remove it and manually test the switch again. If you cannot find and remove the cause of the switching failure, the assembly is defective and must be replaced.

3. If the assembly switches manually, check for loose wire connections to the assembly and look for damaged wires between the assembly and the control panel. Repair any wire problems you find and test the system.


Remove this cover on the left side of the Isolation relays to check the Remote station fuse
