terminal board.
Warning:
If the power supply flexible line or the signal line of the equipment is damaged, only use special
flexible line to replace it.
1、Before connecting lines, read the voltages of the relevant parts on the nameplate. Then carry out
line connection according to the schematic diagram.
2、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.
3、The air-conditioning unit must have grounding to avoid hazard owing to insulation failure.
4、All fitting lines must use crimp terminals or single wire. If multiple twisted wires are connected
to terminal board, arc may arise.
5、All line connections must conform to the schematic diagram of lines. Wrong connection may
cause abnormal operation or damage of the air-conditioning unit.
6、Do not let any cable contact the refrigerant pipe, the compressor and moving parts such as fan.
7、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.
8、shall not be liable for any loss or abnormal operation arising from wrong line connections.
H、Power Cable Connection
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".
Caution:
For
air-conditioner
heater, it is required to connect the
power cable to the "L1, L2 L3
" terminals and the grounding screw.
Caution:
Take great care when carrying out the
following
connections,
so

of
the
air-conditioning
because of electromagnetic interference.
(1) The signal line of the wire controller must
be separated from the power line and the
connecting line between the indoor unit and
the outdoor unit.
(2) In case the unit is installed in a place
vulnerable by electromagnetic interference, it
is
better
to
use
shielded
double-twisted cable as the signal line of the
wire controller.
