Step 10--INSTALL ELECTRICAL CONNECTIONS

The unit cabinet must have an unimetTupted, unbroken

electrical ground to minimize the possibility of serious injury

if an electrical fimlt should occur. This ground may consist of

an electrical wire connected to the unit ground lug in the

control compartment, or conduit approved for electrical

ground when installed in accordance with NEC (National

Electlical Code) ANSIiNFPA (latest edition) and local elec-

trical codes. In Canada, fi_llow Canadian Electrical Code

CSA (Canadian Standards Association) (22.1 and local

electrical codes. Failure to adhere to this warning could result

in serious injm?- or death.

Failure to %tlow these precautions could result in damage to

the unit being installed:

1 Make all electrical connections in accordance with NEC

ANSINFPA (latest edition) and local electrical codes

governing such wiring In Canada, all electrical connec-

tions must be in accordance with CSA standard C22.1

Canadian Electrical (?ode Part 1 and applicable local

codes RefBr to unit wiring diagram.

2 Use only copper conductor fbr 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 Do not damage internal components when drilling through

any panel to mount electrical hardware, conduit, etc. On

3-phase units, ensure phases are balanced within 2 percenL

Consult local power company fbr correction of improper

voltage an&or phase imbalance

HIGH-VOLTAGE CONNECTIONS

The unit must have a separate electrical service with a field-

supplied, waterproof, disconnect switch mounted at, or within

sight fi'om, the unit Refer to the unit rating plate fbr maximum

Nseicircuit breaker size and minimum circuit amps (ampacity) for

wire sizing (See Tables 4 and 5 for electrical data).

The field-supplied disconnect switch box may be mounted on the

unit over the high-voltage inlet hole when the standard power and

tow-voltage entIy points are used (See Fig. 2 and 3 fbr acceptable

location).

See unit wiring label and Fig. 11 fbr refhrence when making high

voltage connections. Proceed as follows to complete the high-

voltage connections to the unit.

Fig. 11--High= and Control=Voltage Connections

Single phase units:

1. Run the high-voltage (LI_ L2) and ground leads into the

control box.

2. Connect ground lead to chassis ground connection.

3. Connect L! to pressure tug connection 11 of the compressor

contactor,

4. Connect L2 to pressure tug connection 23 of the compressor

contactor.

Three-phase units:

1. Run the high-voltage (L!, L2, L3) and ground leads into the

control box.
