To connect the control panel to the electrical source:
1. Locate the opening in the control panel‘s top
housing for the conduit that will enclose the wire
from the facility’s power source. The hole will
accept a 1” conduit fitting. It is 1.3” dia. (33mm).
2. Thread the wire from the power source into the
control panel housing, and then connect the power
source wires to the appropriate terminals on the
DISCONNECT switch.
