INSTALLATION INSTRUCTIONS
CAUTION: Before installing, make certain the A.C. power is off and the IIS-50-I unit connector
is disconnected.
1. MOUNTING THE IIS-50-I
Mount the
IIS-50-I on or adjacent to the fixture in a position that does not interfere with the existing A.C. driver, ballast or
any other hardware. Extend the flex conduit to the junction box or wireway channel and punch a
7
/
8
″
hole. Feed the wires
and flex connector down through the hole in the fixture and secure in place with the flex connector nut. An optional T-bar
mounting kit is available to mount the
IIS-50-I above the ceiling tile adjacent to the fixture. Refer to Illustration 1. To order
the optional T-bar mounting kit (part number TBMK-160) contact Customer Service.
When remote mounting, consult Customer Service for the maximum allowable distance between the inverter and fixture.
CAUTION: Properly secure the IIS-50-I in the ceiling grid to insure compliance with local, state, and federal
guidelines regarding ceiling mounted equipment.
2. WIRING
A. CONNECTING THE INVERTER AC INPUT
This is the AC input that charges the inverter battery, therefore it requires an unswitched AC supply. For 120V supply,
connect the AC line wire to the BLACK lead.
For 277V supply, connect the AC line wire to the ORANGE lead. Connect
the WHITE to the AC Neutral. Refer to the Wiring Diagram on Page 4.
CAUTION: Cap the unused BLACK or ORANGE
input wire. Failure to do so may result in equipment failure and void the warranty.
B. CONNECTING THE NORMAL AC SWITCHED / UNSWITCHED SUPPLY
Connect the BLK/ORG lead to the switched or unswitched AC supply. Connect the WHT/BLU to the AC Neutral. Refer
to the Wiring Diagram on Page 4. For Emergency Only (Normally Off) operation, the BLK/ORG and WHT/BLU leads
are not used and should be capped separately.
Select the appropriate output voltage to the AC driver/ballast on the AC Output Setting (
Voltage Selector) switch (120
or 277 volts) located on the flex end of the
IIS-50-I. Refer to Illustration 2.
C. CONNECTING THE INVERTER TO THE AC FIXTURE
Connect the output leads of the IIS-50-I to the AC fixture. When making connections to the IIS-50-I, do NOT con-
nect the input neutral WHITE or WHT/BLU to the output neutral GRAY. Refer to the Wiring Diagram on Page 4.
For additional wiring diagrams consult Customer Service.
Wire the AC driver/ballast with the lamp(s) in accordance with the manufacturer’s installation instructions.
Install in accordance with the National Electrical Code and local regulations.
INSURE WIRING IS IN ACCORDANCE WITH THE NATIONAL ELECTRICAL CODE AND LOCAL REGULATIONS.
