TRANSFORMER CONNECTION
Attach a 3/4" conduit to the left most wiring hole in the bottom of the controller. Route
the power wires through the conduit and into the wiring cavity.
Use wire nuts to connect the "NEUTRAL" wire to the white transformer wire and the
"HOT" wire to the appropriately colored wire on the transformer. Use the "BLK" wire
for 220V, the "BRN" wire for 240V and the "ORN" wire for 260V.
Tape the two unused transformer wires so that they can't make contact with each
other or with the conduit. See the wiring schematic provided on the body of the 50 HZ
transformer and the figure below.
