• When installing outdoor units in module, select the power
supply cable according to the sum of outdoor unit capacity.
(Refer to the table for each model)
• Power Supply cords of parts of appliances for outdoor use shall
not be lighter than polychloroprene sheathed flexible cord.

CAUTION
• Caution for electrical work
– You must install ELCB or MCCB + ELB
– ELCB: Earth leakage breaker
– MCCB: Molded case circuit breaker
– ELB: Earth leakage breaker
– Do not operate the outdoor unit before completing the
refrigerant pipe work.
– Do not disconnect or change the cable inside the product. It
may cause damage to the product.
– Specification of the power cable is selected based on
following installation condition; culvert installation/ ambient
temperature 30 °C/ single multi conductor cables. If the
condition is different from the ones stated, please consult an
electrical installation expert and re-select the power cable.
– If the length of power cable exceed 50m, re-select the
power cable considering the voltage drop.
– Use a power cable made out of incombustible material for
the insulator (inner cover) and the sheath (outer cover).
– Do not use the power cable with the core wire exposed
due to insulator damage occurred during removal of the
sheath. When the core wire is exposed, it may cause fire.

NOTE
• This device is intended for the connection to a power supply
system with a maximum permissible system impedance shown
in the table (on the left page) at the interface point (power
service box) of the user’s supply.
• The user must ensure that this device is connected only to a
power supply system which fulfills the requirement above. If
necessary, the user can ask the public power supply company for
the system impedance at the interface point.
• This equipment complies with IEC 61000-3-12 provided that the
short-circuit power Ssc is greater than or equal to Ssc(*2) at the
interface point between the user’s supply and the public system.
It is the responsibility of the installer or user of the equipment to
ensure, by consultation with the distribution network operator if
necessary, that the equipment is connected only to a supply with
a short-circuit power Ssc greater than or equal to Ssc(*2).

Power and communication cable
configuration
• Main power and the ground cable must be withdrawn through
the knock-out hole on the bottom-right or right side of the
cabinet.
• Withdraw the communication cable from the designated
knock-out hole on the bottom-right side of the front part.
• Install the power and communication cable using separate
cable protection tube.
• Fix a protection tube to the knock-out hole on the outdoor
unit by using a CD connector or bushing. Make sure to use
insulating bushing.
