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 cable) shall be (50mm[1-5/8in.] or more) apart from power source
wiring so that it is not influenced by electric noise from power source wiring. (Do not insert transmission cable and power
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 380~415V(220~240V) power source to terminal block of transmission cable. If connected,electrical parts
will be burnt out.
Use 2-core shield cable for transmission cable. If transmission cables of different systems are wired with the same
multiple-core cable, the resultant poor transmitting and receiving will cause erroneous operations.
