When installation is finished, the unit must be tested and debugged before operation. Please
refer to Instruction Manual of ODU for auto addressing and debugging details.
5 Wiring Work
Notes:
①
For personal safety, the air conditioner must be properly grounded.
②
Read carefully the voltage indicated on the nameplate before connecting wires. Then connect
wires according to the wiring diagram. Improper wiring will lead to abnormal operation or damage the unit.
③
Power capacity should be large enough. Sectional area of room wires should be above
2.5mm
2
.
④
For unit's power supply, please use specialized branch circuit and specialized power socket.
⑤
All wiring must comply with standards to ensure safe and correct operation.
⑥
Install specialized branch circuit breaker according to related laws and regulations and
electrical standards.
⑦
All wiring must use pressure terminal or single wire. Multi-twisted wire that connects directly
to the wiring board may cause fire hazard.
⑧
Keep the wires away from refrigerant pipe, compressor and fan.
⑨
Do not alter the inner wires of air conditioner. Manufacturer does not assume responsibility
for damage or abnormal operation due to this reason.
⑩
If the unit is installed in places with strong electromagnetic interference, it's recommended
to use twin-twisted shield wire. During wire connection, please pay attention that the metal shield
layer of the twin-twisted wire must be grounded(outer case) in order to prevent the unit from
electromagnetic interference.
11
Communication line should be separated from the power cord and the connection wire of IDU
and ODU.
12
If the project needs higher static pressure, you can set it through the wired controller.
13
The appliance must be fitted with means for disconnection from the supply mains having
a contact separation in all poles that provide full disconnection under overvoltage category III
conditions, and these means must be incorporated in the fixed wiring in accordance with the wiring
rules.
