INSTALLATION INSTRUCTIONS
CAUTION: Before installing, make certain the A.C. power is off and the I-320 unit connector is disconnected.
1. LAMPS OPERATED
2. MOUNTING THE I-320
Remove the ballast channel cover. Mount the I-320 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.
3. 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.
4. INSTALLING THE THREADED BODY TEST SWITCH (TBTS)
Recessed Troffer Fixture – Select a convenient location with proper clearance in the ballast cover and drill or
punch a 7 /
8
″ hole ( 1 /
2
″ knockout). Insert the 7 /
8
″ bushing into the hole. Push the plastic tube through the bushing.
Route the leads of the TBTS through the plastic tube. Connect the LED wires from the unit to the TBTS (Red/Black
or Red w/tag to Red, White/Red to White). Push the entire assembly back into the tube until the lens collar 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.
Strip Fixture – Select a convenient location on the fixture so the TBTS can be seen after installation. Allow for
proper clearance inside the fixture and drill or punch a 1 /
2
″ hole. Remove the nut from the TBTS. Push the TBTS
housing into the 1 /
2
″ hole and secure with the nut. Connect the LED wires from the unit to the TBTS (Red/Black or
Red w/tag to Red, White/Red to White). Refer to Illustration 2.
ATTENTION: Only connect the I-320 to the TBTS LED supplied with the unit. The LED must be replaced
when replacing the unit.
5. WIRING THE A.C. INPUT
A. When the I-320 is installed on the same branch circuit, refer to Illustration 3, Figures A and B for input wiring.
When installed on separate branch circuits, refer to Illustration 3, Figures C and D for input wiring. Per NEC, the
I-320 and A.C. ballast must be on the same panel board.
B. The I-320 requires an unswitched A.C. power source of either 120 or 277 volts; therefore, when used with
switched fixtures, the I-320 input must be wired ahead of the switch. Refer to Illustration 3 for switched and un-
switched fixture wiring diagrams.
C. Refer to the wiring diagrams on the back page for the proper wiring. For wiring diagrams of ballasts not shown,
consult our Customer Service.
