UNITS WITHOUT FACTORY-INSTALLED NON-FUSED
DISCONNECT
When installing units, provide a disconnect switch per NEC
(National Electrical Code) of adequate size. Disconnect sizing
data is provided on the unit informative plate. Locate on unit cabi-
net 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. 17 and the unit label diagram for power wir-
ing connections to the unit power terminal blocks and equipment
ground. Maximum wire size is #2 ga AWG per pole.
Provide a ground-fault and short-circuit over-current protection
device (fuse or breaker) per NEC Article 440 (or local codes). Re-
fer to unit informative data plate for MOCP (Maximum Over-cur-
rent Protection) device size.
All field wiring must comply with the NEC and local
requirements.
All units except 208/230-v units are factory wired for the voltage
shown on the nameplate. If the 208/230-v unit is to be connected
to a 208-v power supply, the control transformer must be rewired
by moving the black wire with the
from the 230-v connection and moving it to the 200-v
terminal on the primary side of the transformer. Refer to unit label
diagram for additional information. Field power wires will be con-
nected line-side pressure lugs on the power terminal block or at
factory-installed option non-fused disconnect.

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 50FC models:
Non-powered and unit-powered. Both types provide a 125-volt
GFCI (ground-fault circuit-interrupter) duplex receptacle rated at
15-A behind a hinged waterproof access cover, located on the end
panel of the unit. See Fig. 21.
Figure 22 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 size 04-06 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
(SystemVu™ controls or RTU Open controller) the weatherproof
cover kit is secured to the basepan underneath the control box. See
Fig. 23.
DISCONNECT ALL POWER TO UNIT AND CONVE-
NIENCE OUTLET. LOCK-OUT AND TAG-OUT ALL
POWER.
Remove the blank cover plate at the convenience outlet; discard
the blank cover.
