Fig. 12 - - Disconnect Switch and Unit
Units with Factory-Installed Non- - Fused 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.
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 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 informative plate. See Fig. 13 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

connection and moving it to the 208-v
terminal on the primary side of the transformer. Refer to
unit label diagram for line-side information.
Affix the crankcase heater warning sticker to the unit
disconnect switch.

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.
Tag-out this switch, if necessary.
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. 14.
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.
Maximum continuous current for this type of convenience
outlet (non- - unit powered) must not exceed 8 Amps.
