terminal or fuse block on units with single point box. See Fig. 18
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
removing the black wire with the
from the 230v connection and moving it to the 200v
terminal on the primary side of the transformer. Refer to unit label
diagram for additional information. Field power wires will be
connected 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

WARNING
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 50GC 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. 23.
Figure 23 shows the Convenience Outlet Utilization label which is
located below the convenience outlet.
NOTE: Unit powered convenience outlets are not available as fac-
tory installed options for single phase (-3 voltage code) models.

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.
On units with electro-mechanical controls the weatherproof cover
kit is shipped in the unit's control box. The kit includes the hinged
cover, a backing plate and gasket.
On units with a factory installed direct digital controller (System-
Vu™ controls or RTU Open controller) the weatherproof cover kit
is secured to the basepan underneath the control box. See Fig. 25.

ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury or
death.
Using unit-mounted convenience outlets: Units with unit-
mounted convenience outlet circuits will often require that two
disconnects be opened to de-energize all power to the unit.
Treat all units as electrically energized until the convenience
outlet power is also checked and de-energization is confirmed.
Observe National Electrical Code Article 210, Branch Cir-
cuits, for use of convenience outlets.
1. Remove the blank cover plate at the convenience outlet; dis-
card the blank cover.
2. Loosen the two screws at the GFCI duplex outlet, until
approximately 1/ -in. (13 mm) under screw heads is exposed.
2
Press the gasket over the screw heads.
3. Slip the backing plate over the screw heads at the keyhole
slots and align with the gasket; tighten the two screws until
snug (do not over-tighten).
