All field wiring must comply with local and national fire,
safety and electrical codes. Power to the unit must be within the
operating voltage range indicated on the unit's nameplate. On
three phase units, phases must be balanced within 2%.
Properly sized fuse or HACR (heating, air-conditioning,
and refrigeration) circuit breakers must be installed for branch
circuit protection. See equipment rating plate for maximum
size.
The unit is supplied with an opening for attaching conduit.
Be certain to connect the ground lead to the ground lug in the
