All electrical work must be done as outlined in this
manual and in accordance with this manual.
Substandard work can result in fire and damage to the
unit.
Use specified cables between units and choose the
cables correctly. If not, an electrical shock or fire may
occur.
Do not open the service cover or access panel for the
indoor or outdoor units without turning OFF the main
power supply. It can result in an electrical shock.
Turn OFF the main power switch of the indoor unit and
the outdoor unit before attempting any electrical wiring
work or a periodical check is performed. If not, it will
result in an electric shock or a fire.
Check to ensure that the indoor fan and the outdoor fan
have stopped before attempting any electrical wiring
work or for any scheduled electrical work that is being
performed.
The wires must be firmly secured. External force applied
to terminals may cause a fire.
It is forbidden to connect a plurality of power lines into
one power terminal block. At the indoor unit side of air
conditioner, power wiring can be extended through a
power distribution box. Be sure to calculate the wiring
capacity carefully, since excessively low wiring capacity
may frequently cause fire.
Do not start the system before all check points are
thoroughly checked.
Wrap the accessory packing around the wires, and plug
the wiring connection hole with the seal material to
protect the product from any condensate or insects.
Tightly secure the wires with the cord clamp inside the
indoor unit.
Secure the cable of wired control using the cord clamp
inside the electric box.But North American products,
Local safety standards are adopted for power wiring.
Tighten screws to the following torques.

This equipment can be installed with a Ground Fault Circuit
Interrupter (GFCI), which is a recognized measure for added
protection to a properly grounded unit. Install appropriate sized
breakers /fuses / overcurrent protection switches and wiring in
accordance to local, state and NEC codes and requirements.
The equipment installer is responsible for understanding and
abiding by applicable codes and requirements. Failure to use a
GFCI can result in electrical shock or fire.
Select wiring capacity according to the table 10.1. Install a GFCI
(Ground Fault Circuit Interrupter) and main switch as shown in
each of the system diagrams below.
