8.15.3 EMC areas: first and second environment
Proper installation and wiring of all connecting cables provided, the ARS 2300 servo drives fulfil the
requirements of product standard EN 61800-3. This standard no longer refers to “classes”, but to so-
called environments. The first environment includes mains supply networks supplying residential
buildings. The second environment includes mains supply networks exclusively supplying industrial
buildings.
The following applies to the ARS 2300 servo drives without external filter measures:

8.15.4 EMC-compliant cabling
The following information has to be complied with for an EMC-compliant set-up of the drive system
(see also
chapter
8
Electrical installation, page 89
):
 In order to keep leakage currents and losses in the motor connecting cable as small as possible,
the ARS 2300 servo drive should be located as close to the motor as possible (see also
chapter
8.15.5 Operation with long motor cables, page 130
).
 The motor cable and the angle encoder cable have to be shielded.
 The shield of the motor cable has to be connected to the housing of the ARS 2300 servo drive
(shield connection terminals). The cable shield also has to be connected to the associated servo
drive so that the leakage currents can flow back into the servo drive causing the leakage.
 The mains-end PE connection has to be connected to the PE connection point of supply
connector [X9].
 The inner PE conductor of the motor cable has to be connected to the PE connection point of
motor connector [X6].
 The signal lines must be as far away from the power cables as possible. They should not be laid in
parallel. If intersections cannot be avoided, they should be perpendicular (that is at a 90° angle) if
possible.
 Unshielded signal and control lines should not be used. If their use is inevitable, they should at
least be twisted.
