7.Electrical Wiring

● Turn OFF the main power switch to the indoor unit and the outdoor unit before electrical wiring work
or a periodical check is performed.
● Check to ensure that the indoor fan and the outdoor fan have stopped before electrical wiring work or
a periodical check is performed.
● Protect the wires, drain pipe, electrical parts , etc. from rats or other small animals. If not protected,
rats may gnaw at unprotected parts and at the worst, a fire will occur.
● Check the item below before turning ON the main switch .
● Tighten screws according to the following torque
M3.5: 1.2N-m
M5: 2.0～2.4 N-m
● Wrap the accessory packing around the wires, and plug the wiring connection hole with the seal
material to protect the product from any condensate water or insects.
● Tightly secure the wires with the cord clamp inside the indoor unit.
● Secure the cable of the remote control switch using the cord clamp inside the electrical box.

7.1 General Check

(1) Make sure that the field-selected electrical components (main power switches, circuit breakers,
wires, conduit connectors and wire terminals) have been properly selected according to the electrical
data given in "9.Common".Make sure that the components comply with National Electrical Code(NEC).
(2) Check to ensure that the power supply voltage is within ±10% of the rated voltage.
(3) Check the capacity of the electrical wires. If the power source capacity is too low, the system
cannot be started due to the voltage drop.
(4) Check to ensure that the ground wire is connected.
(5) Power Source Main Switch Install a multi-pole main switch with a space of 3.5mm or more between
each phase.

7.2 Electrical Wiring Connection

The intermediate connection between the indoor unit and the air panel should be referred to in the
"Installation Manual for Air Panel".
(1) Connect the power supply and earth wires to the terminals in the electrical box.
(2) Connect the wires between the indoor unit and the outdoor unit to the terminals in the electrical box.
