Power supply specifications

Power supply wiring and communication wiring are to be procured locally.

For the power supply specification, follow the table below. Ensure power supply is adequate. An insufficient power supply could result in unit failure.

For specification of the power capacity of the outdoor unit and the power supply wires, refer to the Installation Manual supplied with the outdoor unit.

Indoor unit power supply (*1)

Indoor unit power supply, must have a dedicated supply and be separate to that of the outdoor unit.

Arrange the power supplies to the indoor and outdoor units, so that a common earth leakage breaker and main switch can be used.

Power supply cable specification : Cable 3-core 2.5 mm², in conformity with Design 60245 IEC 57.

Indoor/Outdoor inter-unit wiring, Central controller wiring

(*2) (*3)

Use a 2 core non polarity cable.

To prevent any possible noise issues, use a shielded 2 core wire.

The total stated length of communication wiring is determined by the interconnecting length of indoor to outdoor cable plus the length of the central control communication cable.

Remote controller wiring (*4)

Cable connection

REQUIREMENT

Be sure to locate the cable through the cable connection port of the indoor unit.

Ensure additional wire length of approximately 100 mm at the indoor unit electric parts box. This is to enable ease of any service work in the future.

The low-voltage circuit is provided for the remote controller.

Remove the cover of the electric parts box by removing the mounting screws (3 pcs.) and push the hooking section. (The cover of the electric parts box remains hanged to the hinge.)

Tighten the screws on the terminal block and secure the cables with cord clamp fitted to the electric parts box. (Do not apply tension to the connecting section of the terminal block.)

Using the supplied thermal insulation for the sealing of the cable connecting port, seal the cable connecting port. (Otherwise dew condensation may be caused.)

Mount the cover of the electric parts box ensuring the cables are not pinched. (Mount the cover after the ceiling panel has been wired to the electric box.)
