Test the GFCI receptacle by pressing the TEST button on the
face of the receptacle to trip and open the receptacle. Check for
proper grounding wires and power line phasing if the GFCI re-
ceptacle does not trip as required. Press the RESET button to
clear the tripped condition.
FACTORY-OPTION THRU-BASE CONNECTIONS
This service connection kit consists of a
1
/
2
-in. electrical bulk-
head connector and a
3
/
4
-in. electrical bulkhead connector, all
factory-installed in the embossed (raised) section of the unit
basepan in the condenser section. The
1
/
2
-in. bulkhead connec-
tor enables the low-voltage control wires to pass through the
basepan. The
3
/
4
-in. electrical bulkhead connector allows the
high-voltage power wires to pass through the basepan. See
Fig. 35 for size 08-09 units and Fig. 36 for size 12 units.

Check tightness of connector lock nuts before connecting elec-
trical conduits.
Field-supplied and field-installed liquid tight conduit connec-
tors and conduit may be attached to the connectors on the base-
pan. Pull correctly rated high voltage and low voltage through
appropriate conduits. Connect the power conduit to the internal
disconnect (if unit is so equipped) or to the external disconnect
(through unit side panel). A hole must be field cut in the main
control box bottom on the left side so the 24-v control connec-
tions can be made. Connect the control power conduit to the
unit control box at this hole.
UNITS WITHOUT THRU-BASE CONNECTIONS
1. Install power wiring conduit through side panel openings.
Install conduit between disconnect and control box.
2. Install power lines to terminal connections as shown in
Fig. 24.
ALL UNITS
Voltage to compressor terminals during operation must be
within voltage range indicated on unit nameplate. On 3-phase
units, voltages between phases must be balanced within 2%
and the current within 10%. Use the formula shown below to
determine the percent of voltage imbalance. Operation on im-
proper line voltage or excessive phase imbalance constitutes
abuse and may cause damage to electrical components. Such
operation would invalidate any applicable Carrier warranty.
Example: Supply voltage is 230-3-60
