Connection Rules

1. Always install FOUR (4) lamps. Operating with fewer lamps may overdrive lamp current at maximum brightness settings.

2. Verify lamp wiring before connecting lamps to the inverter module. Connecting multiple lamps to one of the four inverter output

circuits will result in reduced brightness. The LXM1641-01 module connectors are wired per industry standard. The lamp hot wires

(high voltage wires) are always on pin 1 or 2, and the cold wire (low voltage wire) is always on pin 3 or 4.
