INSTALLATIONS

ALL INSTALLATIONS & WIRING SHOULD BE DONE BY QUALIFIED PERSONNEL 

Steps

1. Remove all sources of power.
2. Remove enclosure lid by loosening the 4 front screws, sliding the lid upwards, and carefully pull it forward.
3. There is a cable connecting the lid to the internal circuit board. This can be disconnected from the circuit board on the lid if necessary
4. Make connections per one of the Application diagrams on Pages 5-8 of these instructions.
5. Tighten screw terminals to 10 in-lb. (1.1 Nm) max.
6. Terminal conductor gauge and quantity per Figure 1:
   • a. A Terminals – 12-24 AWG, two conductors maximum per position
   • b. B Terminals – 12-26 AWG, one conductor maximum per position
7. Make sure the enclosure is properly grounded using NEC approved conduit and bonding methods.
8. Put the lid back in place and tighten the lid screws down.
9. Apply all sources of power to the product.
10. Test the unit using one of the Test Procedures on Page 4.
    

OPERATION

This device will automatically transfer a lighting load from a Normal source to an Emergency source upon loss of Normal power. If Normal power is absent, the status of the load cannot be overridden. However, if the Normal power is present, the Emergency lighting load can be controlled by other means in order to use it as a Normal lighting load, depending on the wiring setup.

If it is not already being used for the Application wiring, the Auxiliary relay contacts can be used as status contacts. The contact between terminals

2 and #3 will be closed when Normal power is present and open when Normal

power is lost. The contact between terminals #1 and #3 will be open when Normal power is present and closed when Normal power is lost.

LED DEFINITIONS

Blue LED (Fault Indicator)
This LED will flash when a fault is detected. To return the device to normal operation, the fault must be resolved and power to the unit must be cycled.

Yellow LED (Load Power Indicator)
This LED indicates that there is power available for the connected Emergency lighting load. If the device is wired per one of the Application diagrams that utilizes a switching means, the Load may still be OFF. This LED will always be ON during normal operation. The only time this LED will turn OFF is during a transfer. Whether the transfer is initiated by a remote test input, pressing the integral test switch on the lid, or when Normal power is lost or returns, the Yellow LED will be OFF until the transfer completes.

Red LED (Emergency Power Indicator)
This LED will be ON as long as Emergency power is connected to the unit.

Green LED (Normal Power Indicator)
This LED will be ON as long as Normal power is connected to the unit.

• Check Emergency Power Input wiring and voltage.

Green LED is OFF|

• Check Normal Power Input wiring and voltage.

Yellow LED is ON but Load is OFF|

• If using a Switch or Dimmer Control, make sure it is ON.
• Check Load wiring.
• Verify Load’s operation voltage is the same as the Emergency Power Input Voltage.
• Check bulbs and ballast.
• Replace Unit.

Load is ON but Yellow LED is OFF|

• Replace Unit.

Load does not turn on when being testing|

• Check bulbs and ballast.
• Check wiring connections if using a remote test option.
• If using a Switch or Dimmer Control, make sure it is ON.
• Replace Unit.

Load will not turn OFF when Switch or Dimmer Control is turned OFF|

• Verify status of Utility Power Input.
• Verify no test inputs are stuck closed.

Blue LED is flashing|

• Cycle Emergency Power Input to the unit to reset the fault.
