Instructions Installing Bulletin 500LC Lighting Contactors Use these instructions to install Bulletin 500LC Lighting Contactors. CAUTION To avoid personal injury de–energize the branch circuit and the control line to be connected to the Bulletin 500LC Lighting Contactor.
Installing Bulletin 500LC Lighting Contactors Ratings Bulletin 500LC Lighting Contactors are rated for 20 amps lighting loads and 30 amps general purpose. They are UL508 Listed, CSA Certified, and are available in 2–...12–pole single throw double break and 2–...6–pole normally open and normally closed configurations. Control voltages are from 120...480V AC. See Tables A, B, and C for contact ratings. Table A – Maximum AC Voltage and Amp.
Installing Bulletin 500LC Lighting Contactors 3 Installation Bulletin 500LC Lighting Contactors are tested and ready to use. Installation simply requires mounting, and connection of line and load circuits and control circuit wires. Mounting Six outline and mounting drawings are furnished in this manual. Use Drawing A (page 5 top) for 500LC supplied in a surface or flush Type 1 enclosure. Use Drawing B (page 5 bottom) for 500LC supplied in a Type 3R, 4/4X, or 12 enclosure.
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.
