16.2.3 Details of electrical wiring connection
The electrical wiring capacity of the outdoor unit should be
referred according to "Installation & Operation Manual" of the
outdoor unit. Setting dip switch may be required depending on
the combination with the outdoor unit.
1 Connect the power source cables (L1 and N (L2) phases
(1~ 220-240V 50/60Hz)) to the terminal board correctly.

2 Connect the control cables between the indoor unit and the
outdoor unit correctly.
3 Check to ensure that the terminal for power source cable
(Terminals "L1" to "L1" and "N(L2)" to "N(L2)" of each
terminal board (1~ 220-240V 50/60Hz)) between the indoor
unit and the outdoor unit coincide correctly. If not, some
component will be damaged.
4 Use shielded twisted pair cable for the control cable between
the outdoor unit and the indoor unit, between indoor units.
They are connected to the terminals 1 and 2 of the terminal
boards. The total cable length should be less than 1000m.
5 Use shielded twisted pair cable for the remote control switch
cable. The total cable length should be less than 500m. If the
total length of the cable is less than 30m, other cables can
be used (0.3 to 0.75mm2 ) if comply with local regulations.

The remote control shielded twisted pair cable is connected
to the terminals A and B of each indoor unit terminal board.
6 Check to ensure that the communication cable between
outdoor unit and indoor units (H-Link), comply with Local
regulations and it is not affected by any electromagnetic
noise. It must be a shielded twisted pair cable (≥0.75mm2)
with a total H-Link length <1000m.
7 Control cable: connect the both ends of shielded twisted pair
cable to the earth as shown.

8 Remote control switch cable: Connect the one end of
shielded twisted pair cable to the earth as shown.

9 When installing the unit in Australia, a lockable isolator
shall be mounted adjacent to but not on the units and will
TB1
disconnect all active conductors to the unit from the supply
circuit.

•
Tightly secure wirings to the terminal board according to the
specified torque. If tightening the terminals is not completed,
heat generation, an electric shock or a fire will occur at the
terminal connection.
•
Make sure that the wires are securely fixed in order not to apply
an external force to the terminal connections of the wirings. If
fixing is not completed, heat generation or a fire will occur.
•
Fix the terminals that do not touch to the electrical box surface. If
the terminals are closed to the surface, it may cause activation of
ELB, heat generation at terminal connection, a fire or an electric
shock.
•
Select the wiring size, ELB (Earth Leakage Breaker) and isolating
switch according to each regulation of region and "Installation &
Operation Manual", and the dedicated electrical circuit must be
used.
