All wiring and disconnects must comply with local and
National Electrical Codes™ (NEC). The installer must
provide properly sized system interconnection and
power supply wiring with appropriate fused disconnect
switches.
Electrical connection types, sizes, and locations are
shown in Figure 5, p. 10. Refer
electrical data (MCA, MFS). This information is also
provided on the unit nameplate. Sample wiring
diagrams are provided in this manual.

Power Supply Wiring

Run appropriately sized power wiring and field-
supplied conduit through the line voltage access
opening provided on the front of the unit. Refer to
Figure 1, p. 7 for electrical connection locations. Run
wire and field supplied conduit up to the conduit
connection point located in the bottom of the control
panel. Make appropriate connections to the power
terminal block in the control panel. Install fused
disconnects as required by local codes. Provide proper
equipment ground to the ground connections in the
control panel.
CXRC-SVX01J-EN
toTable 5, p. 20 for

System Interconnection Wiring

Run appropriately sized field supplied conduits, 115
and 24 volt control wiring through the 115 and 24 volt
access openings provided on the front of the unit. Refer
to Figure 5, p. 10 for electrical connection locations.
Run wire and field supplied conduit to the conduit
connection points provided on the bottom of the
control panel. Make appropriate connections to the
terminal blocks in the control panel. Install safety
devices if required by local code. Provide proper
equipment ground to the ground connections in the
control panel. Refer to Table 5, p. 20

Unit Wiring Diagrams

Specific unit wiring diagrams are provided on the
inside of the control panel door. Use these diagrams
for connections or trouble analysis. Refer to the
section, "Wiring Diagrams," p.
wiring diagrams.

Unit Voltage

Electrical power to the unit must meet stringent
requirements for the unit to operate properly. Total
voltage supply and voltage imbalance between phases
must be within the following tolerances as stated
below in the section, "V V o o l l t t a a g g e e I I m m b b a a l l a a n n c c e e " .

Measure each leg of supply voltage at the line voltage
disconnect switch. Readings must fall within voltage
utilization range shown on the unit nameplate. If
voltage of any leg does not fall within tolerance, notify
the power company to correct this situation before
operating the unit. Inadequate voltage to the unit can
for electrical data.
