Installing Bulletin 500LC Lighting Contactors
Line and load terminals are reversible. The Bulletin 500LC
Lighting Contactor is UL Listed for use with 60 or 75˚ C wire. All
power wires should enter enclosure adjacent to the 500LC
terminals. Combination knockouts are provided on Type 1
enclosures. Line and load connections are supplied with clamp
type terminals. These terminals accept the wire sizes #18–10
AWG Cu. Insert appropriate line and load wires and tighten clamp
screws to 18 inch–pounds.
Control Line Connections
Control circuit connections designated L, O, C on the right side are
supplied with clamp type terminals. These terminals accept wire
sizes #18–10 AWG Cu. Simply insert appropriate control wires
and tighten terminal clamp screws to 18 inch–pounds. See the
wiring diagrams.
Install overcurrent protective devices
for the control circuit in accordance
with applicable electrical codes.

Kits
Kits are available for modification of Bulletin 500LC Lighting Contactors
to allow changes in pole configuration, voltage, control modules, and
auxiliary contacts.
Replacement Parts
The main contact blocks and the operator coil are available in kit form.
When ordering parts, provide the Serial No. and Catalog No. from the
Bulletin 500LC Lighting Contactor nameplate.
Auxiliary Contacts Kit – Optional Field Installed Modification
500LC–141C, 500LC–142C
These auxiliary contacts are to be installed on the left side of the Bulletin
500LC. The auxiliary contacts operate along with the main contacts to
provide remote indication of the 500LC position (closed or open).
Each auxiliary contact provides a form C, spdt (single pole double throw)
contact rated 10 amps at 277V AC. Mod. 500LC–141C is one auxiliary
contact, and Mod. 500LC–142C is two auxiliary contacts. A connector
with leads is provided for each auxiliary contact See wiring diagram on
page 13 or 14 for contact configuration, additional ratings, and wiring.

Solid–state Control Modules – Field Installed Modifications
500LC–47CM*, 500LC–48CM*, 500LC–49SS*
These control modules are to be connected and mounted on the bottom or
right side of the Bulletin 500LC Lighting Contactor depending on the
number of 500LC poles or N/O and N/C contact configuration. A control
module can be field installed by ordering the appropriate module kit. Refer
to wiring diagrams on page 13 or 14.
Operation
Mod. 500LC–47CM* control modules are for two–wire control of the
Bulletin 500LC only. The module must be energized to close the 500LC, and
de–energized to open the 500LC. Therefore, use a single pole, maintained
type control station to operate the control module.
Mod. 500LC–48CM* control modules are for three–wire control of the
Bulletin 500LC. One terminal must be energized to close the 500LC; another
terminal must be energized to open the 500LC. If neither or both terminals
are energized, no output will occur. Therefore, use a single pole, double
throw, momentary type control station to operate the control module.
Mod. 500LC–49SS* control modules are for Form 3 (start–stop) control of
the Bulletin 500LC. The modules must be energized to close the 500LC, and
de–energized to open the 500LC. Therefore, use one normally–closed and
one normally–open separate control stations to operate the control module.
There are four different control modules for each Mod. 500LC–47CM*,
500LC–48CM*, and 500LC–49SS*. Each module is suitable only for the
control voltage marked on it. Refer to Table F. Ratings for the control
modules are listed in Table H.

in Figure 1 and to wiring diagram on page 13 or 14. Barrier screw type
terminals accept #22–12 AWG Cu control wiring. Tighten terminals to 12
inch–pounds.
The control modules have two colored leads preconnected to the O and C
terminal bus on the 500LC. A yellow wire runs between the O terminals; and
orange/black wire runs between the C terminals.
Connect your control wiring for the module to terminals 2, 3, and 4 on the
modules. Terminal 2 is not used on Mod. 500LC–47CM* and terminal 1 is
never used.
Connect your control wiring for the 500LC Lighting Contactor (coil voltage)
to terminal 5 on the control module and terminal L on the500LC. If the line
voltage (service) is the same as the coil voltage, the control voltage can some
directly from the poles of the 500LC Lighting Contactor.

noise.
Measure no more than 110%
control voltage (nameplate
coil voltage) between 500LC
terminals L and C, or L and O.
If voltage is high, change control supply
or change Bulletin 500LC Lighting
Contactor.
Manual Operation
A #8–32 screw 1–&frac12; in. long can be used to manually operate the
500LC. One is supplied in all replacement parts kits requiring
manual operation. The screw should be used for maintenance
purposes only. Remove the screw after maintenance.
CAUTION
Do not manually operate the
Bulletin 500LC Lighting Contactor
until all power and control circuits
are disconnected.
Open circuit breakers, then use a voltmeter to verify no voltage is
present at the 500LC at both control and line terminal screws.
Insert the operating screw into the center of the coil and carefully
turn it clockwise until the threads engage the cam/core.
Pull the screw outward to open the 500LC contacts; push it in to
close the contacts. Observe the buttons in the contact block
(buttons out means contacts open).
