Regulation of harmonic currents
This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to Ssc
(*1) 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 (*1)
Furthermore, when similar equipment or other equipment which may cause harmonic current emissions are to be
connected to the same interface point with this equipment, to reduce the risk of possible problems which may be
caused from addition of those harmonic current emissions, it is recommended to make sure that the short-circuit power
Ssc at the interface point is greater than the sum of the minimum Ssc required by all the equipment which will be
connected to the interface point.
Ssc (*1) :
Model Ssc (kW)
