Symptoms/Issue

Due to parts obsolescence from the PSU manufacturer, ETC changed the PSU in Selador Classic beginning Apr 2021

Description/Explanation of Issue

The new PSU is a different size and requires an adapter plate to be able to attach the new supply with the existing standoffs in the fixture. It also requires new harnesses due to a different pinout on the input, and a different number pins on the output header. Part number 7400K1007 includes the standoff plate and the new harnesses. If you're swapping a small supply with a small supply, you'll only need PS496. 

When replacing a PSU with the new PS496, the black and white wires on the AC power harness need to be swapped

If replacing a PSU in a multi-cell fixture, it is NOT required to replace every supply.
