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.

rests against the plastic tube. The plastic tube should be adjusted so that the
TBTS is within ¼ ″ of the fixture lens.
The TBTS must be visible after installation. Refer to Illustration 1.

A. The ISL-540 and A.C. ballast must be on the same branch circuit.
B. The ISL-540 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-540 is used with a switched fixture, the A.C. input to the ISL-540 must be connected ahead of
the fixture switch. Refer to Illustration 3 for switched and unswitched fixture wiring diagrams.
