DC Inverter Cassette Type Air Conditioner Installation and Operation Manual
57
Caution:
During the installation of the bottom plate of the wired controller, pay attention to the direction of the
bottom plate. The plate’s side with two notches must be at the lower position, otherwise the panel of the wired
controller cannot be correctly installed.
Caution:
1. The communication distance between the main board and the wired controller can be as far as 20m (The
standard distance is 8m).
2. The wired controller shall not be installed in a place where there is water drop or large amount of water
vapor.
8.5.13 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 specied on the nameplate.
②
The capacity of the power supply must be large enough. The section area of tting line in the room shall
be larger than that of Table 6 shows.
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 xed line.
1. Connection of single wire
● Use wire stripper to strip the insulation layer (25mm long) from the end of the single wire.
● Remove the screw at the terminal board of the air-conditioning unit.
● User pliers to bend the end of the single wire so that a loop matching the screw size is formed.
● Put the screw through the loop of the single wire and x 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 x the terminal at the terminal board.
Warning:
● If the power supply exible line or the signal line of the equipment is damaged, only use special exible
line to replace it.
● Before connecting lines, read the voltages of the relevant parts on the nameplate. Then carry out line
connection according to the schematic diagram.
● 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.
● The air-conditioning unit must have grounding to avoid hazard owing to insulation failure.
● All fitting lines must use crimp terminals or single wire. If multiple twisted wires are connected to
terminal board, arc may arise.
