The outdoor unit rating plate lists pertinent electrical data neces-
sary for proper electrical service and overcurrent protection. Wires
should be sized to limit voltage drop to 2% (max.) from the main
breaker or fuse panel to the outdoor unit. Refer the NEC, CEC,
and all local codes to determine the correct wire gauge and length.
Local codes often require a disconnect switch located near
the unit; do not install the switch on the unit.

vercurrent rOtectiOn
The inverter control system software provides sufficient time
delay to protect from overcurrent conditions and permit the
compressor and fan motors to adjust their rotational speed.
