FIG. 5 - TYPICAL FIELD WIRING

The internal wiring harness furnished with this unit is an integral part of a ETL and CGA design certified unit. Field alteration to comply with electrical codes should not be required.

A fused disconnect switch should be field provided for the unit. The switch must be separate from all other circuits. Wire entry at knockout openings require conduit fittings to comply with CEC (in Canada), NEC (in U.S.A.) and/or local codes. Refer to the Dimensions and Clearances Figure for installation location. If any of the wire supplied with the unit must be replaced, replacement wire must be of the type shown on the wiring diagram and the same minimum gauge as the replaced wire.

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.

CAUTION: When connecting electrical power and control wiring to the unit, waterproof type connectors

MUST BE USED so that water or moisture cannot be drawn into the unit during normal operation. The above waterproofing conditions will also apply when installing a field-supplied disconnect switch.
