Unscrew the assembly around the outside of the
disconnect switch. This assembly is located in the
condenser section of the unit.
Both high and low voltage power can be routed
through the base or through the front corner post
where the disconnect enclosure is mounted. The
hole is sized for 1 1/2–in. conduit.
2. If the conduit required for your application is larger
than 1 1/2–in., remove the termination plate and
connect to the larger hole using field supplied
reducing washers.
3. Route the power wires and ground conductor
through conduit and into the bottom of the factory
installed disconnect switch. Connect the power
conductors to the lugs provided. Connect the
ground wire to the unit ground lug.
N N o o t t e e : : Wire size for the length of run should be
determined using the circuit ampacity found
on the unit nameplate and the N.E.C.
4. Route low voltage (class II), control wiring through
hole in base of unit but not through high voltage
conduit. Feed control wiring through bushing
provided on side panel. Route wires through loose
wire ties provided.
5. Tighten the wire ties. Secure the excess wire bundle
under the wire ties in the outdoor section. Do not
leave excess wire in the electrical enclosure. Use
the unit wiring diagram to make the low voltage
24
connections.
