Rockwell Automation 500LG User Manual
Control Module Kit for Bulletin 500LG Contactors
(Cat 500LG_)
WARNING
The control module kits are designed for use with Bulletin 500LG lighting contactors only. Control module kits enable conversion of an
electrically held contactor to a mechanically held contactor. These kits are available in either 2-wire or 3-wire control versions in a variety of
voltages. The component parts of a 2-wire control module kit are shown. A 3-wire kit includes an additional single-pole auxiliary contact
block.
To prevent electrical shock, disconnect from power source before installing or servicing. Follow NFPA 70E requirements. Install
in a suitable enclosure. Keep free from contaminants.
Installation or removal of a control module kit to or from the Bulletin 500LG lighting contactor must be performed by a "Qualified
Person" as defined by the National Electrical Code.

The control module kits are for use with the coils up to 277 VAC maximum. Use a control power transformer for higher voltages.
Latch and electronic module must be used together to ensure proper operation. Failure to do so will void warranty.

are assembled to the lighting contactor; one on
the right (N.C.) and one on the left (N.O.). Refer
to Table C on sheet 2 for connection diagram.

For 2-wire control, one auxiliary contact block is
assembled to the right side of the lighting
contactor base for normally closed (N.C.). Two
wires coming from the control module are
connected across the auxiliary contact block.
