• 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 fullls 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).

NOTE
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.
• Specication 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 dierent 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 re.
