Route High Voltage and Ground Wires
Any excess high voltage field wiring should be trimmed
and secured away from any low voltage field wiring. To
facilitate a conduit, a cutout is located on the bottom of
the control box. Connect conduit to the control box using a
proper conduit fitting.
Connect the 208/230 high voltage power supply from the
disconnect to the NS23AMA contactor as shown. Connect
the ground wire from the power supply to the unit ground
lug connection.
