2. Electrical Wiring
WARNING!
● Before obtaining access to terminals, all supply circuits must be disconnected.
● The rated voltage of the unit is as shown as table 3
● Before turning on, verify that the voltage is within the 198~264V range (for single phrase
unit) or 342~457V range (for three-phrase unit).
● Always use a special branch circuit and install a special receptacle to supply power to the
air conditioner.
● Use a special branch circuit breaker and receptacle matched to the capacity of the air
conditioner.
● The special branch circuit breaker is installed in the permanent wiring. Always use a circuit
that can trip all the poles of the wiring and has an isolation distance of at least 3mm
between the contacts of each pole.
● Perform wiring work in accordance with standards so that the air conditioner can be
operated safely and positively.
● Install a leakage special branch circuit breaker in accordance with the related laws and
regulations and electric company standards.
CAUTION!
● The power source capacity must be the sum of the air conditioner current and the current
of other electrical appliances. When the current contracted capacity is insufficient, change
the contracted capacity.
● When the voltage is low and the air conditioner is difficult to start, contact the power
company to raise the voltage.
(1). For solid core wiring (Fig.41)
1). Cut the wire end with a wire cutter or wire-cutting pliers, then strip the insulation about
25mm (15/16") .
2). Using a screwdriver, remove the terminal screw(s) on the terminal board.
3). Using pliers, bend the solid wire to form a loop suitable for the terminal screw.
4). Shape the loop wire properly, place it on the terminal board and tighten securely with
the terminal screw using a screwdriver.
(2). For strand wiring (Fig.41)
1). Cut the wire end with a wire cutter or wire-cutting pliers, then strip the insulation about
10mm (3/8") .
