Only for the 3Ph power supplied units this equipment
complies with IEC 61000-3-12 provided that the short
circuit power Ssc is greater than or equal to 1,32 MVA 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 1,32 MV.
Remove the front panel, the electric parts appear at the
front side.
The power supply cables can be inserted into the pipe
holes. Enlarge the pipe holes if they are too small. Be sure

do not make contact with the compressor and the hot
pipes. To ensure good tensile strength, the electric cables
must be fastened using the cable-holder on the plate (See
