Step 6 — Make Electrical Connections —
wiring must be installed in accordance with job wiring dia-
grams and all applicable electrical codes.
Do not run 120-v wiring into the control cabinet. The con-
trol cabinet should only be used for additional extra-low
voltage wiring (50 v maximum). Damage to machine could
result.

erence only and are not intended for use during actual installa-
tion; follow job specific wiring diagrams.
Do not attempt to start compressor or oil pump (even for a
rotation check) or apply test voltage of any kind while
either chiller module is under dehydration vacuum. Motor
insulation breakdown and serious damage may result.
CONNECT CONTROL INPUTS — Wiring may be speci-
fied for a spare safety switch, and a remote start/stop contact
can be wired to the VFD terminal strip. Additional spare sen-
sors and Carrier Comfort Network
as well.
CONNECT CONTROL OUTPUTS — Connect auxiliary
equipment, chilled and condenser water pumps, and spare
