If a neutral conductor is used together with a three-phase connection, it can‐
not be installed unfiltered in areas B and C in order to keep interference off
the mains.
Single-phase or three-phase supply lines for motor fans that are usually rout‐
ed parallel to motor power cables or lines prone to interference must be fil‐
tered:
● In drive systems with regenerative supply units through a separate sin‐
gle-phase (NFE type) or three-phase filter (NFD type) near the mains
connection of the control cabinet
● In drive systems with only feeding supply units through the available
three-phase filter of the drive system
On the load side of the mains filter, voltage against ground with a high
rise of voltage dv/dt can be present and interfere with the additional
loads connected there.
When switching power off, make sure the fan is not switched off.
Only operate allowed loads at the mains filter of the drive system!
At the three-phase filter for the power connection of regenerative
supply units, it is only allowed to operate the following loads:
● HMV supply unit with mains choke and, if necessary, mains
contactor
Do not operate any motor fans, power supply units etc. at the
mains filter of the drive system.
If there is still a high degree of interference injection on the mains supply line
in the control cabinet although you have observed the above instructions (de‐
termine using EMC measurement to standard), proceed as follows:
● Only use shielded lines in area A
● Connect shields to the mounting plate at the beginning and end of the
line with clips
The same procedure may be required for cables longer than 2 m between the
point of power supply connection for the control cabinet and the filter in the
control cabinet.
Ideally, mount the mains filter on the parting line between areas A and B.
Make sure the ground connection between filter housing and drive controller
housing is electrically highly conductive.
If single-phase loads are connected on the load side of the filter, their current
may be a maximum of 10% of the three-phase operating current. A highly im‐
balanced load on the filter would reduce its interference suppression capaci‐
ty.
If the mains voltage is more than 480 V, connect the filter to the output side of
the transformer and not to the supply side of the transformer.
In the case of bad ground connections in the system, the distance between
the lines to grounding points E1 and E2 in area A and the other grounding
points of the drive system should be at least d4 = 400 mm in order to mini‐
mize interference injection from ground and ground cables to the mains sup‐
ply lines.

The equipment grounding conductor of the power cable for the machine, sys‐
tem or control cabinet has to be permanently connected at point PE and have
a cross section of at least 10 mm
ment grounding conductor using separate terminal connectors (according to
