3.6 Electromagnetic compatibility
EMC immunity to
interference
According to EN 61000-6-2
(industrial environment)
EMC interference emission According to EN 61000-6-4
(industrial environment)
If several devices are switched in parallel on the
supply side so that the line current of the
arrangement is in the range of 16 – 75 A, then this
arrangement conforms to IEC 61000-3-12 provided
that the short-circuit power S
sc
at the connection point
of the customer system to the public power system is
greater than or equal to 120 times the rated output of
the arrangement. It is the responsibility of the
installation engineer or operator/owner of the device
to ensure, if necessary after a consultation with the
network operator, that this device is only connected to
a connection point with a S
sc
value that is greater
than or equal to 120 times the rated output of the
arrangement.
