9.11 Electric Installation
CAUTION
Before installing the electrical equipment, please pay attention to the following matters which have been
specially pointed out by our designers:
Check if the power supply conforms to the rated power supply specifi ed on the nameplate.
1.
The capacity of the power supply must be large enough.
2.
The cables must be installed by professional personnel.
3.
An electricity leakage protection switch and an air switch with gap between electrode heads larger than 3mm
shall be installed in the fi xed line.
Connection of single wire
1.
Use wire stripper to strip the insulation layer (25mm long) from the end of the single wire.
(1)
Remove the screw at the terminal board of the air-conditioning unit.
(2)
User pliers to bend the end of the single wire so that a loop matching the screw size is formed.
(3)
Put the screw through the loop of the single wire and fi x the loop at the terminal board.
(4)
Connection of multiple twisted wires
2.
Use wire stripper to strip the insulation layer (10mm long) from the end of the multiple twisted wires.
(1)
Remove the screw at the terminal board of the air-conditioning unit.
(2)
Use crimping pliers to connect a terminal (matching the size of the screw) at the end of the multiple
(3)
twisted wires.
Put the screw through the terminal of the multiple twisted wires and fi x the terminal at the terminal
(4)
board.
WARNING
If the power supply fl exible line or the signal cable of the equipment is damaged, use only special fl exible line
to replace it.
Before connecting cables, read the voltages of the relevant parts on the nameplate. Then carry out line
1.
connection according to the schematic diagram.
The air-conditioning unit shall have special power supply cable which shall be equipped with electricity
2.
leakage switch and air switch, so as to deal with overload conditions.
The air-conditioning unit must have grounding to avoid hazard owing to insulation failure.
3.
All fi tting cables must use crimp terminals or single cable. If multiple twisted wires are connected to termi-
4.
nal board, arc may arise.
All cable connections must conform to the schematic diagram of lines. Wrong connection may cause
5.
abnormal operation or damage of the air-conditioning unit.
Do not let any cable contact the refrigerant pipe, the compressor and moving parts such as fan.
6.
Do not change the internal cable connections inside the air-conditioning unit. The manufacturer shall not
7.
be liable for any loss or abnormal operation arising from wrong cable connections.
