WIRING
NOTE: All wiring should be made in accordance with the National
Electrical Code.
Consult your local Power Company to determine the availability of
sufficient power to operate the unit. Check the voltage, frequency,
and phase at the power supply to ensure it corresponds to the
unit’s RATED VOLTAGE REQUIREMENT.
In accordance with the N.E.C. or local codes, install a branch circuit
fused disconnect near the unit. Determine wire sizes and overcur-
rent protection from the unit nameplate ampacity and in accor-
dance with the Branch Circuit Ampacity table on the next page or
the N.E.C. The wiring should never be sized smaller than is recom-
mended by either of these two sources.
Fuses smaller than that recommended on the rating plate could result in
unnecessary fuse failure or service calls. The use of protective devices of
larger size than indicated could result in extensive damage to the equip-
ment. The manufacturer bears no responsibility for damage caused to
equipment as result of the use of larger than is recommended size pro-
tective devices.
All units have undergone a run test prior to packaging for shipment. This
equipment has been started at minimum rated voltage and checked for
satisfactory operation. Do not attempt to operate this unit if the voltage
is not within the minimum and maximum voltages shown on nameplate.
All exterior wiring must be within approved weatherproof conduit. The
unit must be permanently grounded in accordance with local codes, or in
absence of local codes, with N.E.C ANSI/ NFPA NO. 70-1984 or latest edi-
tion by using ground lug in the control box.
Fuses or HACR type circuit breakers may be used where codes permit.

power supply is broken with the contactor.
To wire the unit, make the following high and low voltage connections.
