3 Refer to the data plate on the bottom of the plasma power supply for more information about duty cycle and for International Electrotechnical Commission (IEC) ratings.
4 NOTICE: This Class A equipment is not intended for use in residential locations where the public low voltage supply system supplies the electrical power. It is not always easy to supply electromagnetic compatibility in those locations, because of conducted and radiated disturbances.
5 This product meets the technical requirements of IEC 61000-3-3 and is not subject to conditional connection.
6 Equipment complies with IEC 61000-3-12.
7 Equipment complies with IEC 61000-3-12 if the Short-circuit power (Ssc) is greater than or equal to 1003 KVA at the interface point between the operator’s supply and the public system. The installer or user of the equipment must consult with the distribution network operator, if necessary, to ensure that the equipment is connected only to an electric power source with a Ssc greater than or equal to 1003 KVA.
8 F5 is only recommended to cut stainless steel.
