ENGLISH Electrical Wiring Electrical Wiring 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 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. CAUTION Be sure to correct the outdoor 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 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 transmitting and receiving will cause erroneous operations. ( mark in the figure below) 7. Only the communication line specified should be connected to the terminal block for Outdoor Unit communication.

CAUTION
Be sure to correct the outdoor 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.
