This Class A equipment is not intended for use in residential locations where the electrical power is provided by the public
low-voltage supply system. There may be potential difficulties in ensuring electromagnetic compatibility in those locations due to
conducted or radiated disturbances.
3
This product meets the technical requirements of IEC 61000-3-3 and is not subject to conditional connection.
4
Equipment complies with IEC 61000-3-12 provided that the short-circuit power S
sc
is greater than or equal to 5363 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 5363 KVA.
