disconnected.
1. LAMPS OPERATED
2. MOUNTING THE I-42-EM-A
When used with ceiling mounted downlight fixtures, the
I-42-EM-A should be mounted on the fixture above the
ceiling. The flex conduit marked “A” 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 1 for typical mounting.
When battery packs are remote mounted, consult Customer Service for the maximum allowable distance between
the battery pack and the lamp.
3. MOUNTING THE THREADED BODY TEST SWITCH (TBTS)
Cut a single gang switch box into the ceiling tile adjacent to the fixture within reach of the
I-42-EM-A flex
marked “B”. After mounting the switch box, connect flex “B” to the box and route all leads inside the box. Refer to
Illustration 1 for typical mounting.

I-42-EM-A
TBTS
INSURE WIRING IS IN ACCORDANCE WITH THE NATIONAL ELECTRICAL CODE AND LOCAL REGULATIONS.
4. WIRING
A.
When
the
I-42-EM-A is installed on the same branch circuit, refer to Illustration 2, Figures A and B for
input wiring. When installed on separate branch circuits, refer to Illustration 2, Figures C and D for input wiring.
Per NEC, the
I-42-EM-A and A.C. ballast must be on the same panel board.
B. The
I-42-EM-A requires an unswitched A.C. power source of either 120 or 277 volts; therefore, when
used with switched fixtures, the
I-42-EM-A input must be wired ahead of the switch. Refer to Illustration 2
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.
6. COMPLETING INSTALLATION
When the installation is complete, switch the A.C. power on and join the
I-42-EM-A unit connector.
