ELECTRICITY WIRING
Cautions
• Regard to the regulations about electric facility and electric lines, follow the policy of technical
standard governmental organizations and directions of an electric companies.
• Separate the communication lines with outdoor units and sensor signal lines from power lines
so that they are not affected by the electric noise caused by communication lines and power
lines (Don’t let them pass through the same electric lines).
• Be sure to do the grounding for an inverter drive kit.
• Never connect the main line with communication lines and the terminal sockets of sensor sig-
nal lines. If connected, electric components and sensors are damaged.
• Do not use 2-line shield as a communication line.
If one shield cable is connected to the other system, receiving and sending communication will
be deteriorated and an abnormal operation will occur.
WARNING
• Following the relevant regulations and current installation manual, use an electric techni-
cian for the electric works which require special circuits. When there is an insufficient elec-
tric supply circuit capacity or a defect, an electric shock or fire could occur.

WARNING
• In accordance with the relevant regulations and current installation manual, let a qualified
electricity engineer do the electric works which uses special circuits. When there is an
insufficient electric supply circuit capacity or a defect, an electric shock or fire could occur.
!
WARNING
• Be sure to ground an inverter drive kit. Do not connect the ground lines with gas pipes,
water pipes, a lightning rod, or telephone line ground lines. Incomplete ground causes an
electric shock.
