The air conditioner rating plate lists pertinent electrical data
necessary for proper electrical service and overcurrent protec-
tion. Wires should be sized to limit voltage drop to 2% (max.)
from the main breaker or fuse panel to the air conditioner.
Consult 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.
o p
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.

• Make sure to apply the rated voltage of 208/230V for the
unit.
• A power circuit (see the following table) must be provided
for connection of the unit. This circuit must be protected
with the required safety devices.
• When using residual current operated circuit breakers, be
sure to use a high-speed type (0.1 seconds or less) 200
mA rated residual operating current.
• Use copper conductors only.
• Use insulated wire for the power cord.
• Select the power supply cable type and size in accor-
dance with relevant local and national regulations.
