Caution
1. Follow ordinance of your governmental organization for technical standard related to electrical equipment, wiring
regulations and guidance of each electric power company.
WARNING
Be sure to have authorized electrical engineers do the electric work using special circuits in
accordance with regulations and this installation manual. If power supply circuit has a lack of
capacity or electric work deficiency, it may cause an electric shock or fire.
2. Install the Outdoor Unit transmission line away from the power source wiring so that it is not affected by electric
noise from the power source. (Do not run it through the same conduit.)
3. Be sure to provide designated grounding work to Outdoor Unit.
CAUTION
Be sure to correct the outdoor unit to earth. Do not connect earth line to any gas pipe, liquid pipe,
lightening rod or telephone earth line. If earth is incomplete, it may cause an electric shock.
4. 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.
5. Never connect the main power source to terminal block of transmission line. If connected, electrical parts will
be burnt out.
6. Use 2-core shield cable for transmission line.(O mark in the figure below) If transmission lines of different sys-
tems are wired with the same multiplecore cable, the resultant poor transmitting and receiving will cause erro-
neous operations. (
7. Only the transmission line specified should be connected to the terminal block for Outdoor Unit transmission.
