your area.) If a de-energize via unit disconnect switch operation of
the convenience outlet is desired, connect the source leads to the
load side of the unit disconnect. On a unit without a unit-mounted
disconnect, connect the source leads to compressor contactor C
and indoor fan contactor IFC pressure lugs with unit field power
leads (see Fig. 46).
Fig. 46 — Power Wiring Connections (Sizes 07-14)
Fig. 47 — Power Wiring Connections (Size 16)
Field power wires are connected to the unit at line-side pressure
lugs on compressor contactor C and indoor fan contactor IFC (see
wiring diagram label for control box component arrangement) or
at factory-installed option non-fused disconnect switch. Max wire
size is #4 AWG (copper only) (sizes 07-14) and #2 AWG (copper
only) (size 16).
FIELD POWER SUPPLY (SIZE 16)
See Fig. 47. For those units without thru-the-curb power, conduit
must be used to route the main power from the condenser end, via
the power entry in the corner post of the unit (see Fig. 48 and 49)
to either the factory option disconnect or the bottom of the control
box. A 1-in. conduit is provided wrapped around compressor. A
second conduit is provided with factory-installed powered conve -
nience outlet. For those units that require conduit larger than 1-in.,
it must be field supplied. Fig. 48 and 49 show the wire routings.
If the field disconnect is larger than 100A, it must be attached to
the unit using accessory CRDISBKT001A00 — disconnect
switch bracket (see Fig. 50). Follow the instructions provided with
this accessory. For smaller field disconnects, be sure to use

screws to mount the disconnect directly to the end panel (see
Fig. 51). In either case, set the disconnect vertical location on the
unit so that a 90 degree fitting can be used to connect the conduit
to the disconnect.
