Electrical Wiring

1. Follow ordinance of your governmental organization for technical standard related to electrical equipment,
wiring regulations and guidance of each electric power company.
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 Outside Unit transmission line away from the power source wiring so that it is not affected by elec-
tric noise from the power source. (Do not run it through the same conduit.)
3. Be sure to provide designated grounding work to Outside Unit.
Be sure to correct the outside unit to earth. Do not connect earth line to any gas pipe, water 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 Outside Units, because the box is some-
times 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. ( mark in the figure below)
7. Only the transmission line specified should be connected to the terminal block for Outside Unit transmission.
