INSTALLATION INSTRUCTIONS
CAUTION: Before installing, make certain the A.C. power is off and the
ISL-54 unit connector is disconnected.
1. MOUNTING THE ISL-54
Remove the ballast channel cover. Mount the ISL-54 in the ballast channel at least 1/2″ away from the A.C.
ballast(s).
When battery packs are remote mounted, consult Customer Service for the maximum allowable distance between
the battery pack and the lamp.
2. WIRING
Refer to the wiring diagrams on the back page for the appropriate wiring of lamp(s) and ballast. Install in accordance
with the National Electrical Code and local regulations. For additional wiring diagrams consult Customer Service.
3. INSTALLING THE CHARGE INDICATOR
Select a convenient location on the side of the fixture so the Charge Indicator can be seen after installation.
Allow for proper clearance inside the fixture and drill or punch a ½″ hole. Snap the ½″ white bushing into the hole.
Push the LED housing into the bushing and secure it in place with a 5/8″ black bushing (see Illustration 1).
Connect the LED red and white wires to the ballast LED marked wires.

4. INSTALLING THE TEST SWITCH
The Test Switch should be mounted on the side of the fixture, preferably adjacent to the charge indicator. Drill or
punch a ½″ mounting hole.
5. WIRING THE A.C. INPUT
A. The ISL-54 and A.C. ballast must be on the same branch circuit.
B. The ISL-54 requires an unswitched A.C. power source of either 120 or 277 volts. Select the proper voltage
lead and cap the unused lead.
C. When the ISL-54 is used with a switched fixture, the A.C. input to the ISL-54 must be connected ahead of the
fixture switch. Refer to Illustration 2 for switched and unswitched fixture wiring diagrams.
