How to Install Control Modules
To avoid personal injury or property
damage, de–energize both line and control
power connected to the Bulletin 500LC
Lighting Contactor before proceeding.
CAUTION
Recommended Tools Screwdriver, needle–nose pliers
1. Open circuit breakers, then use a voltmeter to verify no voltage is present at
both control and line terminal screws.
2. Label, disconnect, and tape all wires (control, line, load) from the lighting
contactor.
3. The control module can be mounted to the Bulletin 500LC Lighting
Contactor on the bottom or right side depending on the number of poles:
2–...6–poles, bottom mounting
Mount the control module at the base of the lighting contactor. Install the
screws supplied with control module in outer holes (in legs) of module. Use
the inner holes on the contactor frame. Tighten the screws evenly to 5 in–lbs.
Refer to Figure 1.
Do not overtighten the mounting screws !
8–...12–poles, side mounting
Mount the control module (tabs) on the right side of the lighting contactor
with the two contact block screws. Loosen the two existing screws on the right
side of the upper and lower contact blocks. Back out the screws to clear the
cut outs in the contact blocks so that the module’s mounting tabs can be
inserted. Retighten the two screws (through the module’s mounting tabs) to
10 in–lbs. Refer to Figure 2.
