(2) Do not connect the power source cables to
the control line. It will cause a burnout of the
printed circuit board.
(3) Connect the control cables between the
indoor unit and the outdoor unit, as shown in
Fig. 7.2 to 7.4.
Check to ensure that the terminal for power
source cable (Terminals “L1” to “L1” and “N”
to “N” of each terminal board: AC220-240V)
between the indoor unit and the outdoor unit
coincide correctly. If not, some component
will be damaged.
(4) Use the shielded twist pair cable for control
between the outdoor unit and the indoor
units. They are connected to the terminals
1 and 2 of the terminal boards. The remote
control switch cable is connected to the
terminals A and B of each indoor unit
terminal board.
(5) When installing the unit in Australia, connect
the both ends of shielded twist pair cable
(remote control switch cable and control
cable) to the earth as shown below.
O
Connect correctly the power source line phases.
3-Phase 4 Wires: L1, N
3-Phase 3 Wires: L1, L2
O
In the case of 3-Phases 4 Wires type
The power source must be applied from L1 line
and N line. If applied from L1-L2, L1-L3, the
electrical parts will be damaged.
O
The control cable between the indoor unit and
the outdoor unit does not have any polarity.
Do not apply an excessively high voltage to the
cable (Rated Voltage 5V). It may cause failure.
O
The remote control switch cable (Field-Supplied)
does not have any polarity. Do not apply an
excessively high voltage to the cable (Rated
Voltage 5V). It may cause failure.
NOTES:
1. When the total wiring length for control
cable between the outdoor unit and the
indoor unit and between indoor units is
less than 100m, the normal wiring (more
than 0.75mm
2
) except the twist pair cable
is available. (Except for Australia)
2. The total wiring length for the remote
control switch can be extended up to
500m. If the total wiring length less than
30m, the normal wiring (0.3mm
2
) except
the twist pair cable is available. (Except
for Australia)
O
Install an ELB in the power source.
If ELB is not used, it will cause electric shock

O
The tightening torque of each screw shall be
as follows. Keep the tightening torque below
when wiring work.
M4:
1.0 to 1.3 N-m
M5:
2.0 to 2.5 N-m
M6:
4.0 to 5.0 N-m
M8:
9.0 to 11.0 N-m
M10: 18.0 to 23.0 N-m
O
Connect earth wires for the outdoor / indoor
unit to prevent an electrical shock or an
unexpected accident. The earth resistance
must be less than 1 megohm. The earth work
must be performed by authorized installers.
O
Turn completely OFF the power source to
prevent an electrical shock when opening the
service cover to perform the electrical work
or the maintenance.
O
Pay attention not to bite electrical wirings
when attaching the service cover. It may

O
Maintain the rated voltage for the power source.
It may be harmful to the unit if the voltage is
either too high or too low.
O
Take enough capacity for the power source.
If not, the operation can not be started by the
wide voltage reduction.
(1) Connect the power source cables (L1 and L2
(N) phases) to the terminal board correctly.
