3.4 EMC-compliant Installation

To obtain an EMC-compliant installation, follow the instructions provided in the drive-specific design guide and the installation
guide included in the shipment.

3.4.1 Grounding

• Ensure that all stations connected to the fieldbus network are connected to the same ground potential. When distances be-
tween the stations in a fieldbus network are long, connect the individual station to the same ground potential. Install equalizing
cables between the system components.
• Establish a grounding connection with low HF impedance, for example, by mounting the drive on a conductive backplate.
• Keep the ground wire connections as short as possible.

3.4.2 Cable Routing

EMC INTERFERENCE
Failure to isolate fieldbus communication, motor, and brake resistor cables can result in unintended behavior or reduced per-
formance.
-
Use shielded cables for motor and control wiring, and separate cables for fieldbus communication, motor wiring, and brake
resistor.
-
Minimum 200 mm (7.9 in) clearance between power, motor, and control cables is required. For power sizes above 315 kW
(450 hp), increase the minimum distance to 500 mm (20 in).
