● Only use shielded lines in area A
● Connect shields to the mounting plate at the beginning and the end of
the line by means of clips
The same procedure may be required for long cables of more than 2 m be‐
tween the point of power supply connection of the control cabinet and the fil‐
ter within the control cabinet.
Mains Filters for AC Drives
Ideally, mount the external mains filter on the parting line between area A and
B. Make sure the ground connection between filter housing and housing of
the drive controllers has good electrically conductive properties.
If single-phase loads are connected on the load side of the external filter,
their current may be a maximum of 10 % of the three-phase operating cur‐
rent. A highly imbalanced load of the external filter would deteriorate its inter‐
ference suppression capacity.
If the mains voltage is higher than 480 V, connect the external filter to the
output side of the transformer and not to the supply side of the transformer.
Grounding
In the case of bad ground connections in the installation, the distance be‐
tween the lines to the grounding points E1, E2 in area A and the other
grounding points of the drive system should be at least d4 = 400 mm, in order
to minimize interference injection from ground and ground cables to the pow‐
er input lines.

Point of Connection for Environ‐
ment Grounding Conductor at Ma‐
chine, Installation, Control Cabinet
The equipment grounding conductor of the power cable of the machine, in‐
stallation or control cabinet has to be permanently connected at point PE and
have a cross section of at least 10 mm
2
or to be complemented by a second
equipment grounding conductor via separate terminal connectors (according
to EN 61800-5-1: 2007, section 4.3.5.4). If the cross section of the outer con‐
ductor is bigger, the cross section of the equipment grounding conductor
must be accordingly bigger.
