I. Power Cable Connection
Caution:
Before installing the electrical equipment, please pay attention to the following
matters which have been specially pointed out by our designers:
（ 1 ） Check that if the power supply used conforms to the rated power supply specified on the
nameplate.
（
2
）
The capacity of the power supply must be large enough. The section area of fitting line in
the room shall be larger than 2.5 mm
2
.
（ 3 ） The lines must be installed by professional personnel.
An electricity leakage protection switch and an air switch with gap between electrode heads
larger than 3 mm shall be installed in the fixed line.
1.Connection of single wire
（ 1 ） Use wire stripper to strip the insulation layer (25mm long) from the end of the single wire.
（
2
）
Remove the screw at the terminal board of the air-conditioning unit.
（ 3 ） User pliers to bend the end of the single wire so that a loop matching the screw size is
formed.
（
4
）
Put the screw through the loop of the single wire and fix the loop at the terminal board.
2. Connection of multiple twisted wires
（
1
）
Use wire stripper to strip the insulation layer (10mm long) from the end of the multiple
twisted wires.
（ 2 ） Remove the screw at the terminal board of the air-conditioning unit.
（
3
）
Use crimping pliers to connect a terminal (matching the size of the screw) at the end of the
multiple twisted wires.
（ 4 ） Put the screw through the terminal of the multiple twisted wires and fix the terminal at the
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.
