3) The air-conditioning unit shall have special power supply line which shall be equipped with
electricity leakage switch and air switch, so as to deal with overload conditions.
4) The air-conditioning unit must have grounding to avoid hazard owing to insulation failure.
5) All fitting lines must use crimp terminals or single wire. If multiple twisted wires are connected to
terminal board, arc may arise.
6) All line connections must conform to the schematic diagram of lines. Wrong connection may
cause abnormal operation or damage of the air-conditioning unit.
7) Do not let any cable contact the refrigerant pipe, the compressor and moving parts such as fan.
8) Do not change the internal line connections inside the air-conditioning unit. The manufacturer
shall not be liable for any loss or abnormal operation arising from wrong line connections.
10.5.13 Connection of the Power Cable
1. Air-conditioning unit with single-phase power supply
1) Remove the front-side panel of the outdoor unit.
2) Pass the cable though rubber ring.
3) Connect the power supply cable to the "L, N"
terminals and the grounding screw.
4) Use cable fastener to bundle and fix the cable.
2. Air-conditioning unit with 3-phase power supply
1) Remove the front-side panel of the outdoor unit.
2) Attach rubber ring to the cable-cross hole of the
outdoor unit.
3) Pass the cable though rubber ring.
4) Connect the power cable to the terminal and
earthing screws marked "L1, L2, L3 & N".
5) Use cable fastener to bundle and fix the cable.
10.6 Products Electric Installation
The unit should be reliably earthed, if it is improperly earthed that may cause electric
shock or fire.
Wiring layout
☆ 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,
Take great care when carrying
out the following connections, so
as to avoid malfunction of the
air-conditioning unit because of
electromagnetic interference:
In case the unit is installed in a
place vulnerable by
electromagnetic interference, it
is better to use shielded cable or
double-twisted cable as the
signal wire.
