Electrical wiring & Application control
Warning
Electrical installation should be entrusted with qualified servicemen and done in accordance with the
installation manual. Special return circuit must be used. Insufficient capacity return circuit and
inappropriate installation may lead to fire accidents.
Specific cables should be used for the wiring. To avoid external tension of the cables, the terminals
should be firmly fixed. Inappropriate connection and fixture may lead to fire accidents.
The unit must be earthed.
The unit should be earthed properly. Poor earth may lead to shocks. The earth wire should not be
connected to gas pipes, water pipes, lightning rods or telephone wires.
Caution
Electric leak breaker should be installed. Without it, shock accidents may occur.
To avoid danger, damaged cable must be replaced by professionals of cable makers or the like. Wires
used by the indoor unit should be selected according to the installation manual.
Never connect the block terminal in the control circuit (A, B, C, P, Q, X and Y) to a 220-230V or a
380-400V power line. Otherwise, it may lead to mechanical damage or personal injury.
Avoid contact of electric wires with high temperature pipes to prevent melting of the outer isolation.
Wires should be made into a ì Uî shape after connected to the block terminal, and fixed with clips.
Controlling wires may be laid and fixed together with the refrigerant tubes.
If the supply cord is damaged,it must be replaced by the manufaturer or its service agent or a similar
qualified person.
The wiring method should be in line with the local wiring standard.
All the cables shall have got the European authentication certificate.
The breaker of the air conditioner should be all-pole switch,and the distance between its two contacts
should be no less 3mm.Such means for disconnection must be incorporation in the fixed wiring.
The power cable and connecting cable are self-provided.
Power specifications
The specifications of the power circuit are listed in the table below. Smaller capacity may cause
overheat or burnout.

Electrical wiring & Application control
Indoor power wiring
The indoor and outdoor units should use separate special power lines.
If several indoor units connect the same outdoor unit, the leak breakers and
switches of the indoor units should use the same power.
Centralized controller communication wiring
The centralized controller communication wire are
non-polarity 2-core wires. (Fig. 1)
To prevent electromagnetic disturbance, please use shielded wires.
Remote controller wiring
The remote controller remote is polarized 3-core wires.
The grouped wire controller wire (between the indoor and indoor
units) is polarized 2-core wires. (Fig. 2)
