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 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.
4.7 Ex areas
The device may only be used according to the specifications in the
operating instructions; see Chapter 3. Intended use.
Zone classification
The zones describe how long an explosive atmosphere may be present.
Zones 1 and 2 permit only gases, vapors and mist (no dust) which
occur occasionally to seldom in normal operation.
