This section describes how to wire the Model 4069P power control system. The
features and options mentioned here are identified in the model number found inside
the enclosure.
WARNING!
Hazardous voltages are present at the main disconnect switch and load terminals.
Always remove AC line voltage from the system before making contact with internal
assemblies, line or load wiring, or fuses. Also remove AC line voltage from the
system
before making connections, equipment changes, or resistance measurements.
Conduit entry into the system should be made near the right side of the cabinet for
power wiring. Assure that metal fragments are not allowed to fall into the equipment
while holes are made for conduit fittings. See Figure 1. Referring to the wiring
specification in the table, connect the external power lines to the top of the disconnect
switch.
