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.
Units with Factory-Installed Disconnect —
The factory-installed option disconnect switch is located
in a weatherproof enclosure located under the main
control box. The manual switch handle is accessible
through an opening in the access panel.
All Units —
All field wiring must comply with NEC and all local
codes. Size wire based on MCA (Minimum Circuit Amps)
on the unit informative plate. See Fig. 11 for power wiring
connections to the unit contactor and terminal block and
equipment ground.
Provide a ground-fault and short-circuit over-current
protection device (fuse or breaker) per NEC Article 440
(or local codes). Refer to unit informative data plate for
MOCP (Maximum Over-current Protection) device size.
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

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.
Tag-out this switch, if necessary.

WARNING
Two types of convenience outlets are offered on 569J
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. 12.

Non-powered type: This type requires the field
installation of a general-purpose 125-volt 15-A circuit
powered from a source elsewhere in the building. Observe
national and local codes when selecting wire size, fuse or
breaker requirements and disconnect switch size and
location. Route 125-v power supply conductors into the
bottom of the utility box containing the duplex receptacle.
Unit-powered type: A unit-mounted transformer is
factory-installed to stepdown the main power supply voltage
to the unit to 115-v at the duplex receptacle. This option also
includes a manual switch with fuse, located in a utility box
and mounted on a bracket behind the convenience outlet;
access is through the unit’s control box access panel. See
Fig. 12.
The primary leads to the convenience outlet transformer are
not factory-connected. Selection of primary power source is
a customer-option. If local codes permit, the transformer
primary leads can be connected at the line-side terminals on
the unit-mounted non-fused disconnect or HACR breaker
switch; this will provide service power to the unit when the
