PROCEDURE 7—INSTALL ELECTRICAL CONNECTIONS
WARNING: ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
The unit cabinet must have an uninterrupted, unbroken electrical ground to minimize the possibility of personal injury if an
electrical fault should occur. This ground may consist of an electrical wire connected to the unit ground in the control
compartment, or conduit approved for electrical ground when installed in accordance with NEC (National Electrical Code),
ANSI (American National Standards Institute)/NFPA (latest edition) (in Canada, Canadian Electrical Code CSA C22.1) and
local electrical codes.
CAUTION: UNIT DAMAGE HAZARD
Failure to follow these precautions may result in damage to the unit being installed:
1. Make all electrical connections in accordance with NEC ANSI/NFPA (latest edition) and local electrical codes governing
such wiring. In Canada, all electrical connections must be in accordance with CSA standard C22.1 Canadian Electrical
Code Part 1 and applicable local codes. Refer to unit wiring diagram.
2. Use only copper conductor for connections between field-supplied electrical disconnect switch and unit. DO NOT USE ALUMINUM
WIRE.
3. Be sure that high-voltage power to unit is within operating voltage range indicated on unit rating plate.
4. Insulate low-voltage wires for highest voltage contained within conduit when low-voltage control wires are run in same conduit as
high-voltage wires.
5. Do not damage internal components when drilling through any panel to mount electrical hardware, conduit, etc. Consult local power
company for correction of improper voltage.
A. HIGH-VOLTAGE CONNECTIONS
The unit must have a separate electrical service with a field-supplied, waterproof disconnect switch mounted at, or within sight from the unit. Refer
to the unit rating plate for maximum fuse/circuit breaker size and minimum circuit amps (ampacity) for wire sizing. See Table 6 for electrical data.
The field-supplied disconnect may be mounted on the unit over the high-voltage inlet hole. (See Fig. 2.)
