POWER AND CONTROL WIRING

Field wiring to the unit must conform to provisions of the current N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordinances. The unit must be electrically grounded in accordance with local codes or, in their absence, with the N.E.C./C.E.C. Voltage toler- ances which must be maintained at the compressor terminals during starting and running conditions are indicated on the unit Rating Plate and Table 3.

Electrical line must be sized properly to carry the load. Each unit must be wired with a separate branch circuit fed directly from the meter panel and properly fused.

Refer to Figure 2 for typical field wiring and to the appropriate unit wiring diagram for control circuit and power wiring information.

The wiring entering the cabinet must be provided with me- chanical strain relief.

A fused or HACR breaker disconnect switch should be field pro- vided for the unit. If any of the wire supplied with the unit must be replaced, replacement wire must be of the type shown on the wir- ing diagram.

COMPRESSORS

Units are shipped with compressor mountings factory-adjusted for shipping. CAUTION: Loosen compressor mounting bolts half turn before operating unit.
