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 name Ssc (*1) (kVA)

This unit complies with EN 61000-3-11.
However, the impedance of the power supply system to be connected to the unit at the incoming power
point must be less than the Zmax given below.
In order to meet this condition, consult with the supply authority as required.

In addition, it is recommended that voltage drops occurring during the unit’s operation in the area at the
power input shall be around 3.3% of the nominal power-supply voltage or less.
