WIRING — LOW VOLTAGE WIRING

230/208V, 1 phase and 3 phase equipment dual primary
voltage transformers. All equipment leaves the factory
wired on 240V tap. For 208V operation, reconnect from
240V to 208V tap. The acceptable operating voltage
range for the 240 and 208V taps are:

The electrical data lists fuse and wire sizes (75ºC
copper) for all models, including the most commonly
used heater sizes. Also shown are the number of field
power circuits required for the various models with
heaters.

The unit rating plate lists a “Maximum Time Delay
Relay Fuse” or “HACR Type” circuit breaker that is to
be used with the equipment. The correct size must be
used for proper circuit protection and also to assure that
there will be no nuisance tripping due to the momentary
high starting current of the compressor motor.

The disconnect access door on this unit may be locked
to prevent unauthorized access to the disconnect. To
convert for the locking capability, bend the tab located
in the bottom left hand corner of the disconnect opening
under the disconnect access panel straight out. This tab
will now line up with the slot in the door. When shut, a
padlock may be placed through the hole in the tab
preventing entry.

Five (5) wires should be run from thermostat subbase to
the 24V terminal board in the unit. A five conductor, 18
gauge copper, color-coded thermostat cable is
recommended. The connection points are shown in
Figure 10.
