Condenser operation on improper line voltage or exces-

sive phase imbalance may be considered abuse and any re-

sulting damage may not be covered by Carrier warranty.

All wiring must be in accordance with local or NEC

(National Electrical Code) regulations. Refer to Fig. 13 for

national and applicable local codes.

For ﬁeld power connections, all main power wiring enters

the unit control box using ﬁeld-supplied wirenuts. Be sure to

install a ground wire. See Fig. 13.

CONTROL CIRCUIT POWER WIRING — Connect 24-v

control wires to the 2 low-voltage connections at the com-

pressor contactor. Use ﬁeld-supplied wirenuts to make the

connections in the control box low-voltage section.
