ELECTRICAL WIRING
Precaution
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 transmission cable 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
Follow ordinance of your governmental organization for technical standard related to electrical
equipment, wiring regulations and guidance of each electric power company.
4
Give some allowance to wiring for electrical part box of the indoor and outdoor units. The box
is sometimes removed at the time of service work.
5
Never connect the main power source to the terminal block of transmission cable. If connect-
ed, electrical parts will be burnt out.
6
Use 2-core shield cable for transmission cable.
If transmission cables of different systems are wired with the same multiple core cable, the
poor transmitting and receiving will cause erroneous operation.
7
Only the specified transmission cable should be used in the terminal block for the outdoor
unit transmission.
8
For the grounding power cables for the indoor unit, use the cables as below.
- A corrosive-resistant metal cable with equivalent or higher strength/size of annealed copper
wire with 1.6mm in diameter
- A single cord or a single cap-tire cable with more than 1.25mm
2
cross section
- A double-conductor cable with more than 0.75mm
2
cross section which is a cable com-
pressed or twisted by two conductors from each side.
• Only licensed electricians should do the electrical work using special circuits in accor-
dance with regulations and this installation manual. Insufficient capacity or any defects of
the power supply circuit may cause fire or electric shock.
WARNING
!
• Be sure to ground the outdoor unit. Do not connect the ground wire to any gas pipes, liquid pipes,
lightening rod or telephone ground wire. Incomplete grounding may cause electric shock.
WARNING
!
• Use round pressure terminals for connections to the power cable. It may cause fire or
flame damages on the electrical parts.
• Make sure that the power unbalance ratio is not greater than 5%. If it is greater the unit's
lifespan will be reduced.
• Use the 2-core shield cables.
• Do not use them together with power cables.
• Do not use the multi-core cables.
