11. WIRING
Attaching wiring
●
The air conditioner should use separate power supply with rated
voltage.
●
The external power supply to the air conditioner should have
ground wiring, which is linked to the ground wiring of the indoor
and outdoor unit.
●
The wiring work should be done by qualified persons according
to circuit drawing.
●
A leakage protector should be installed according to the National
Standard concerning electrical appliance.
●
Be sure to locate the power wiring and the signal wring well to
avoid cross-disturbance and their contact with connecting pipe
or stop value body.
●
The wiring attached to this air conditioner is 10m long. Be sure
to prolong it with wiring of the same type and proper length if
necessary. Generally, do not twist two wiring together unless
the joint is soldered well and covered with insulator tape.
●
Do not turn on the power until you have checked carefully after
wiring.

Terminal board diagram
Please refer to the indoor unit wiring diagram for the detailed
wiring. In accord with the communication wiring, terminal board
wiring is different according to the horsepower of air-conditioners.
The wiring of 71T1 to 160T1 indoor unit, please refer to Fig.11-3,
and Fig.11-4 is the wiring for 200T1, 250T1 and 280T1 indoor unit.

Communication Wiring Chart
Communication wiring will be different according to the horse-
power of air-conditioners. The wiring of 71T1 to 160T1 indoor
unit, please refer to Fig.11-1, and Fig.11-2 is the communication
wiring for 200T1, 250T1 and 280T1 indoor unit.
The air-conditioners can connect with Central Control Monitor
(CCM). Before operation, please wiring correctly and set
system address and network address of indoor units.
Please use 3-core shielding wire, and ground the shielding layer.
