2. MOUNTING THE I-42-EM-B
Mount
the
I-42-EM-B in the ballast channel or enclosed wireway so the wire leads are not exposed, at least ½
″
away from the A.C. ballast(s). Refer to Illustration 1. For mounting the
I-42-EM-B on top of the fixture, use the
optional TMK-80 mounting accessory for covering the wires that enter the fixture. Refer to Illustration 2.
When battery packs are remote mounted, consult Customer Service for the maximum allowable distance between
the battery pack and the lamp(s).
3. INSTALLING THE THREADED BODY TEST SWITCH (TBTS)
Select a convenient location on the side of the fixture so that the
TBTS can be seen after installation. Allow for
proper clearance and drill or punch a ½
″ hole. Remove the nut from the TBTS. Push the TBTS housing into the
½
″ hole and secure with the nut. Connect the LED wires from the unit to the TBTS (Red/Black or Red w/tag to
Red, and White/Red to White).
4. WIRING
A. When the
I-42-EM-B 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-42-EM-B and A.C. ballast must be on the same panel board.
B. The
I-42-EM-B requires an unswitched A.C. power source of either 120 or 277 volts; therefore, when
used with switched fixtures, the
I-42-EM-B input must be wired ahead of the switch. Refer to Illustration 3
for switched and unswitched 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.
5. LABELS
Attach the appropriate labels adjacent to the
TBTS. Annotate Re-lamping label for lamp type and wattage. The
Caution and the Re-lamping labels must be on the fixture in a readily visible location to anyone attempting to ser-
vice the fixture.
