FIGURE 1.9
VAC Supply Wiring Landing Points
NOTE: Right-hand access model wiring landing points
are shown here; left-hand access models will
mirror this image.
The electrical data lists fuse and wire sizes (75°C
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 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.
Route all field wires to the right of the wire shield as
shown in the circuit routing label found in Figure 1.8
(and also on the wall-mount units).
IMPORTANT
277/380/575 1-phase and 3-phase equipment
use dual primary voltage transformers. All
equipment leaves the factory wired on 575V tap.
It is very important that the correct voltage tap
is used.

See Figure 1.9 to reference VAC landing points.
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.
