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 communication line. If connected,
electrical parts will be burnt out.
6) Use 2-core shield cable for communication line.(O mark in the figure below) If communication
lines of different systems are wired with the same multiplecore cable, the resultant poor transmit-
ting and receiving will cause erroneous operations. ( mark in the figure below)

1. Caution
1) Follow ordinance of your governmental organization for technical standard related to electrical
equipment, wiring regulations and guidance of each electric power company.
2) Install the Outdoor Unit communication 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.
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 sup-
ply circuit has a lack of capacity or electric work deficiency, it may cause an elec-
tric shock or fire.
