Connection Rules
1. Always install two (2) lamps. Operating with only one lamp may overdrive lamp current at maximum brightness settings.
2. Verify lamp wiring before connecting lamps to the inverter module. Connecting both lamps to one of the two inverter output
circuits will result in reduced brightness. The LXMG1621-01 / 02 module connectors are wired per industry standard. The lamp
hot wires (high voltage wires) are always on pin 1 and / or 2, and the cold wire (low voltage wire) is always on pin 3 or 4.
3. The LXMG1621-04 uses the reverse pinout found in some panels. The lamp hot wires (high voltage wires) are on pins 2 and 3
and the cold (low voltage wire) is on pin 1.
