4 ELECTRIC WIRING WORK
4.1 Wiring Principle
4.1.1General
Perform wiring of the power supply in conformance with the regulations of the local electric
company.
For the control wires connecting indoor units, and between indoor and outdoor units, use of
double-core shield wires is recommended to prevent noise trouble.
Be sure to set the earth leakage breaker and the switches to the power supply section of the
indoor unit.
Supply power to each outdoor unit and provide an earth leakage breaker or hand switch for
each outdoor unit.
Store wiring system for control and refrigerant piping system in the same line.
Arrange the cables so that the electric wires do not come to contact with high-temperature
part of the refrigerant pipe; otherwise coating melts and an accident may be caused.
Do not turn on power of the indoor unit until vacuuming of the refrigerant pipe will finish.
Installation should be conducted by National Wiring Regulation.
The rated voltage and exclusive power supply must be adopted for the air conditioners.
The power cable should be reliable and fixed, in order to avoid the wiring terminal be
suffered from force. And do not drag the power cable forcibly.
The wire diameter of power cable should be large enough, if power cable and connection
wire be damaged, it should be replaced by the exclusive cable.
All electric installation must be done by professional personnel according to local law,
regulation and this manual.
It should be reliably earthed, and it should be connected to the special earth device, the
installation work should be operated by the professional.
The creepage protect switch and air switch must be installed.
Air switch should have the thermal dropout and magnetic dropout function, in order to avoid
the short circuit and overload.
The on spot connection should refer to the circuit diagram, which is stuck on the unit body.
The unit should be reliably earth, if it is improperly earthed that may cause electric shock or
fire.
Air conditioner is the "I" class electric appliance, thus please do conduct reliable grounding
measure.
The yellow-green two-color wiring of air conditioner is grounding wire and cannot be used
for other purposes. It cannot be cut off and be fixed by screw, otherwise it would cause
electric shock.
The user must offer the reliable grounding terminal. Please don't connect the grounding wire
