3 Harmonics situation of each model regarding IEC 61000-3-2 and IEC 61000-3-12 is as follows:
Equipment complying with IEC 61000-3-2
(*) professional use
Equipment complying with IEC 61000-3-12
This equipment complies with IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or
equal to xx (see Ssc column) 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 xx (see Ssc column)
Installation restrictions may be applied by supply authorities in relation to harmonics
D A N G E R
• Never connect the earth cable to the refrigerant pipes. The gas in the pipes could cause a fire.
• Do not connect the earth cable to the lighting arrest system. The electrical potential of earth would increase
abnormally.
5 Check to ensure that the power supply voltage is within +/-10% of the rated voltage.
6 Check to ensure that power supply has an impedance low enough to warranty not reduce the starting voltage more
than 85% of the rated voltage.
7 Check to ensure that the ground wire is connected.
8 Connect a fuse of specified capacity.
