*1): The above wiring line length shows the case that the indoor units are connected in series. (The voltage drop is within 2%.) When the power
source wiring is longer than the above value, select the minimum wiring size which the voltage drop is within 2%.

Check the recommended size of the ELB-CB shown in table. Select
high-sensitive high speed ELB when the rated sensitive current is
less than 30mA. (The motion time should be within 0.1 second.)
•
Use 2 core cable or 2 core twist pair cable (Shielded twist pair cable
for the total wiring length more than 100m) for the control cable
between the outdoor unit and the indoor unit. The total cable length
should be less than 1000m.

Use 2 core twist pair cable for the remote control switch cable and the
control cable between indoor units. 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 (the cable size is 0.3mm
•
Select the wiring size, ELB (Earth Leakage Breaker) and isolating
switch (CB) according to each regulation of region and Installation
and Operation Manual, and the dedicated electrical circuit must be
used.
•
On the outside indoor unit, the power source cable, control cable and
remote control cable shall be installed separately as possible.
2 When installing the optional air panel, connect the connector
for the auto swing motor and the connector for the indoor
unit. Refer to the technical documentation of the optional air
panel for details.
