Specification of the circuit breaker and power cable
Power Supply cords of parts of appliances for outdoor use shall not be lighter than polychloroprene sheathed
flexible cord. (Code designation IEC:60245 IEC 66 / CENELEC: H07RN-F)
※ 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)
ex) Outdoor unit installation (AM100MXW∗ + AM120MXW∗)

• This device is intended for the connection to a power supply system with a maximum permissible
NOTE
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).
