UNITS WITHOUT FACTORY-INSTALLED NON-FUSED
DISCONNECT OR HACR
When installing units, provide a disconnect switch per NEC (Na-
tional Electrical Code) of adequate size. Disconnect sizing data
is provided on the unit informative plate. Locate on unit cabinet
or within sight of the unit per national or local codes. Do not
cover unit informative plate if mounting the disconnect on the
unit cabinet.
ALL UNITS
All field wiring must comply with NEC and all local codes. Size
wire based on MCA (Minimum Circuit Amps) on the unit infor-
mative plate. See Fig. 31 and the unit label diagram for power wir-
ing connections to the unit power terminal blocks and equipment
ground. Maximum wire size is #2ga AWG (copper only) per pole
on contactors. See Fig. 31 and unit label diagram for field power
wiring connections.

Provide a ground fault and short circuit over-current protection de-
vice (fuse or breaker) per NEC Article 440 (or local codes). Refer
to unit informative data plate for MOCP (Maximum Over-Current
Protection) device size.
NOTE: Units ordered with factory installed HACR do not need an
additional ground fault and short circuit over-current protective
device unless required by local codes.
All field wiring must comply with the NEC and local
requirements.
All units except 208/230v units are factory wired for the voltage
shown on the nameplate. If the 208/230v unit is to be connected to
a 208v power supply, the control transformer must be rewired by
moving the black wire with the
the 230v connection and moving it to the 200v
nal on the primary side of the transformer. Refer to unit label dia-
gram for additional information. Field power wires will be con-
nected at line-side pressure lugs on the power terminal block or at
factory-installed option non-fused disconnect.
NOTE: Check all factory and field electrical connections for
tightness.

CONVENIENCE OUTLETS

ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or
death.
Units with convenience outlet circuits may use multiple
disconnects. Check convenience outlet for power status before
opening unit for service. Locate its disconnect switch, if
appropriate, and open it. Lock-out and tag-out this switch, if
necessary.
Two types of convenience outlets are offered on 48HC models:
non-powered and unit-powered. Both types provide a 125-v GFCI
(ground-fault circuit interrupter) duplex receptacle rated at 15A
behind a hinged waterproof access cover, located on the end panel
of the unit. See Fig. 37.

Installing Weatherproof Cover
A weatherproof while-in-use cover for the factory-installed conve-
nience outlets is now required by UL standards. This cover cannot
be factory-mounted due its depth; it must be installed at unit instal-
lation. For shipment, the convenience outlet is covered with a
blank cover plate.
