Middle Outputs are Flickering on SmartPack

If your middle outputs are flickering (outputs 5-8 on a 12-channel, or 3 and 4 on a 6-channel), then your SmartPack may be setup as Single Phase incorrectly. If you're set up as three phase, then this solution probably does not apply.

Some SmartPacks have labels on the WRONG CABLES to tell you which of the 2A and 2B cables go where depending on single phase or three phase. The table below is the correct setup.

A quick summary of the wire placements for both modes:

Power Feed

Wires on Each Terminal




3 Phase

1A, 1B

2A, 2B

3A, 3B

Single Phase

 1A, 1B, 2A 


 2B, 3A, 3B 

If wired incorrectly, your SmartPack dimmers may not fade properly or may jump to full when set at a low level. For more information on hooking up your SmartPack as single or three phase, check out this article.
