• 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
NOTE
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 distri-
bution 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).
