1-1. General cautions

Follow ordinance of your governmental organization for technical standard related to electrical equipment, wiring

regulations, and guidance of each electric power company.

Wiring for control (hereinafter referred to as transmission ) shall be (50mm[1-5/8in] or more) apart from power source

source wire in the same conduit.)

Be sure to provide designated grounding work to outdoor unit.

Give some allowance to wiring for electrical part box of indoor and outdoor units, because the box is sometimes removed

at the time of service work.

Never connect 100V, 208~230V power source to terminal block of transmission . If connected,electrical parts will be
burnt out.

Use 2-core shield cable for transmission .

If transmission

of different systems are wired with the same

multiplecore cable, the resultant poor transmitting and receiving will cause erroneous operations.
