To use a single protection with three fuses on the input line to a system consisting of several
DM2020, the size required will be the one that is the next size larger than the sum of the currents of
the individual systems.
Safety switches for fault currents
According to the EN 60204-1 standard for electrical equipment of machinery, a safety switch for fault
currents can be used provided it meets all applicable regulations and provisions. To protect against
direct accidental contact, a fault currents (leakage) safety switch with 30 mA sensitivity needs to be
installed on each power supply system/modules-axis.
5.3.5.3 Ground Connection
In the electrical panels, there are normally two types of grounds:
l
EMC Ground (high frequency) using unpainted areas of the metal panel, where the drives and
the filters are positioned, to create an adequate electrical contact for the mitigation of high
frequency noise.
l
Safety Ground (PE = protective earth) according to standard EN 60204-1, to be performed with
a minimum wire cross section of 10 mm
2
.
The length of the individual cables that connect to the ground should be minimal, so it is advisable to
place a grounding bar as close as possible to the drives.
