Before installing any connecting wiring, see drawings
Dimensions and Weights chapter for the electrical
access locations provided on the unit. Install
appropriately sized control wiring for the 115 volt
electrical components as required by the application.
Since the unit-mounted 115V control power
transformer (1T1) is provided on all units, it is not
necessary to run a separate 115 volt control power
source to the unit.
N No otte e:: All 200/230V units are shipped with transformer
1T1 wired for 200 volt operation. If the unit is to
be operated on a 230V power supply, rewire the
transformer as shown on the unit schematic.
When the 115 volt control circuit is properly connected
to the field provided interlock contacts 5K1 for circuit #1
and 5K2 for circuit #2 (if applicable), proper condenser
fan cycling and ambient control for the remaining fans
is achieved with corresponding compressor operation.
N No otte e:: All field wiring must conform to NEC guidelines
as well as state and local codes.

If night setback operation is desired, connect a set of
normally open contacts (field provided) to the
appropriate terminals on the terminal board (7TB7), in
the unit’s control panel. Remove the factory installed
jumper at the terminal board when making the final
wiring termination. Refer to the field connection
diagram, numbers 2307-9122 (for 20 to 60 ton units)
and 2307-9144 (for 80 to 120 ton units) for details.
