INSTALLATION INSTRUCTIONS
CAUTION: Before installing, make certain the A.C. power is off and the I-462 unit connector is disconnected.
1. MOUNTING THE I-462
Remove the ballast channel cover. Mount the I-462 on the fixture top in a position that does not interfere with the existing A.C.
ballast or any other hardware. Extend the flex conduit to a convenient location on top of the fixture 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 I-462 above the ceiling tile adjacent to the emergency fixture. To order the optional
T-bar mounting kit (part number TBMK-160) contact Customer Service.
When used with ceiling mounted downlight fixtures, the I-462 should be mounted on the fixture above the ceiling or on the
optional T-bar mounting kit. The flex conduit should be wired into the ballast/lamp compartment or to an electrical junction box
on the fixture which allows access to the ballast/lamp connections. Refer to Illustration 2 for typical mounting.
When battery packs are remote mounted, consult Customer Service for the maximum allowable distance between the battery
pack and the lamp(s).
CAUTION: Properly secure the I-462 in the ceiling grid to insure compliance with local, state, and federal guidelines
regarding ceiling mounted equipment.
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
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. Disconnect the leads from the
LED housing and route the leads down the plastic tube. Reconnect the leads to the housing, observing the proper polarity
(Red/Black or Red lead w/connector to positive (+) red tab). 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 Charge Indicator is within ¼ ″ of the fixture lens.
The Charge Indicator must be visible after installation. Refer to Illustration 1.
Ceiling-Mounted Downlight Fixture – 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 1 /
2
″ hole. Disconnect the leads from
the LED housing. Push the LED housing into the 1 /
2
″ hole until it is firmly locked in place. Reconnect the leads, observing the
proper polarity (Red/Black or Red lead w/connector to positive (+) red tab). Refer to Illustration 2. For remote mounting the
charge indicator and test switch, the optional RTK accessory kit can be ordered.
4. INSTALLING THE TEST SWITCH
The test switch should be mounted on the ballast channel cover of a recessed troffer, or on the side of a strip fixture, preferably
adjacent to the charge indicator. Drill or punch a 1 /
2
″ mounting hole. Refer to Illustration 2.
5. WIRING THE A.C. INPUT
A. The I-462 requires an unswitched A.C. power source of either 120 or 277 volts. Select the proper voltage lead and cap the
unused lead.
B. When the I-462 is used with a switched fixture, the A.C. input to the I-462 must be connected ahead of the fixture switch.
Refer to Illustration 3 for switched and unswitched fixture wiring diagrams.
C. When installed on separate branch circuits, refer to Illustration 3, Figures C and D for input wiring. Per NEC, the I-462 and
A.C. ballast must be on the same panel board.
