4.5 Installation of Wired Controller
Please refer to User Manual of Wired Controller for the installation details.
Note:
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 Wire Connection
Warning!
Before obtaining access to terminals, all supply circuits must be disconnected.
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
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 connecting wire of IDU and
ODU.
12
If the project needs higher static pressure, you can set it through the wired controller.
