How to Install a Replacement Coil
To avoid personal injury or property
damage, de–energize both line and control
power connected to the Bulletin 500LC
Lighting Contactor before proceeding.
CAUTION
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. Loosen the mounting screws and remove the Bulletin 500LC Lighting
Contactor from the enclosure.
Disassembly
Coil assembly is mounted in center of the lighting contactor base. See Figure 1.
4. Disconnect the coil leads. Carefully pull the coil lead with the flag terminal off
the side of the miniature switch; the lug can be pushed from behind. Then
loosen the terminal screw closest to the coil to disconnect the other coil lead.
See Figure 2.
5. Remove the coil assembly. Use a screwdriver (counterclockwise) to remove
the two screws in the magnet frame. Then pull the coil assembly and
nameplate straight out.
Note: Leaf spring and actuator are loose parts on 2–...6–pole lighting
contactors. On lighting contactors with more than 6 poles the leaf spring is not
present, and the actuator is held in place by the lower contact block.
6. Remove the coil. Slide the coil out of the right side of the magnetic frame.
