* Equipment complies with IEC 61000-3-12.
** Equipment complies with IEC 61000-3-12 provided that the short-circuit power S
sc
is greater than or equal to
692 KVA 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 S
sc
greater than or equal to 692 KVA.
