• 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
• 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
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).

Caution for electrical work
• You must install ELCB or MCCB + ELB
Caution
-
ELCB: Earth leakage 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
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.
