no longer refers to "classes", but to so-called environments. The first environment includes mains supply networks that supply
residential buildings. The second environment includes mains supply networks that exclusively supply industrial buildings.
The following applies to the item Servo Positioning Controller C 3-Series without external filter measures:
Table 48:
EMC requirements: first and second environment
EMC type Area Compliance with the EMC requirements
Interference emission First environment (residential environment) Motor cable length up to 50 m,
C‘
≤ 200 pF/m
Second environment (industrial environment)
Interference immunity First environment (residential environment) Motor cable length up to 50 m,
C‘
≤ 200 pF/m
Second environment (industrial environment)
8.14.4 EMC-compliant cabling
The following must be considered for the EMC-compliant set-up of the drive system (see also
chapter 8 Electrical installation,
page 74
):

In order to keep the leakage currents and losses in the motor connecting cable as small as possible, the item Servo
Positioning Controller C 3-Series should be located as close to the motor as possible (see also
chapter 8.14.5 Operation
with long motor cables, page 111
).

The motor cable and angle encoder cable must be shielded.

The shield of the motor cable must be connected to the housing of the item Servo Positioning Controller C 3-Series
(shield connection terminals). The cable shield must also be connected to the associated servo positioning controller so
that the leakage currents can flow back into the controller causing the leakage.

The mains-end PE connector must be connected to the PE connection point of the supply connector [X9].

The inner PE conductor of the motor cable must be connected to the PE connection point of the 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 (i.e. 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.

Even shielded cables will inevitably have short unshielded ends (unless shielded connector housings are used). In
general, the following applies:

Connect the inner shields to the associated pins of the connectors. Maximum length: 40 mm.

Maximum length of the unshielded cores: 35 mm.

Connect the overall shield on the controller side to the PE terminal over a large contact area. Maximum length:
40 mm.

Connect the overall shield on the motor side to the connector or motor housing over a large contact area. Maximum
length: 40 mm.
