incorrect wiring could cause malfunction or even damage the unit.
2)
The capacity of power supply must be sufficient and the sectional area of wires in the room
should be above 2.5mm
2
(AWG 26).
3)
The unit should be powered by independent circuit and specific socket.
4)
The wiring should be in accordance with related regulations in order to ensure the units
operate reliably.
5)
Install circuit breaker for branch circuit according to related regulations and electrical
standards.
6)
All wiring must use pressure terminal or single wire. Multi-twisted wire that connects directly
to the wiring board may cause fire hazard.
7)
Keep cable away from refrigerant piping, compressor and fan motor.
8)
Do not alter the inner wires of air conditioner. Manufacturer does not assume responsibility
for damage or abnormal operation due to this reason.
9)
If the unit is installed in places with strong electromagnetic interference, it's recommended
to use twin-twisted shield wire. During wire connection, please pay attention that the metal
shield layer of the twin-twisted wire must be grounded (outer case) in order to prevent the
unit from electromagnetic interference.
10)
The communication wires should be separated from power cord and connection
wire
between indoor unit and outdoor unit.
11)
If the project needs higher static pressure, you can set it through the wired controller.
12)
The appliance must be fitted with means for disconnection from the supply mains
having
a contact separation in all poles that provide full disconnection under overvoltage
category
III conditions, and these means must be incorporated in the fixed wiring in
accordance with
the wiring rules.
5.1 Connection of Wire and Patch Board Terminal
(1)
Connection of single branch wire (as shown in Fig 5.1.1).
1)
Use a stripper to strip away about 25mm
(1in)
of the insulation layer at the end of
single
branch line so that the single-core wire can be exposed.
2)
Remove the wiring screws on the terminal board.
3)
Shape the tail of wire into ring by needle nose plier, and keep the gauge of ring in
accordance with screw.
4)
Lead the screw across the circle of the single branch line and fix it on the wiring board.
(2)
Connection of multi-twisted wire (as shown in Fig 5.1.2).
1)
Use a wired stripper to strip away about 10mm
(3/8in)
of the insulation layer at the end
of multi-twisted wire.
2)
Loosen the wiring screws on patch board.
3)
Use a round terminal fastener or a plier to securely fasten the round terminal with each
core wire of the multi-core wire.
4)
Confirm the position of each core wire on the round terminal and then use a screwdriver
