VLT® Servo Drive System ISD 510/DSD 510
Operating Guide
-
The PSM 510, DAM 510, and ACM 510 (optional) must be mounted in a control cabinet.

5.3 EMC-Compliant Installation

To achieve an EMC-compliant installation, follow the instructions provided in
the steps defined for connecting the ISD 510/DSD 510 servo drives, PSM 510, DAM 510, and ACM 510.

5.4 Grounding

5.4.1 Grounding for Electrical Safety

• Ground the DSD 510 servo drives with the PE wire of the feed-in cable. There is a dedicated PE screw on the front and another
on the back of the DSD 510 servo drive.

• Ensure that the machine frame has a proper electrical connection to the ISD 510 and DSD 510 servo drives:
- For ISD 510: Use the flange surface on the front side. Ensure PE connection on that part of the machine.
- For DSD 510: Use the PE screw shown in
• For the ISD 510/DSD 510 servo drives, ensure a minimum ground wire cross-section of at least 10 mm
separate ground wires both complying with the dimensioning rules. See EN/IEC 61800-5-1 for further information.
• Use a dedicated ground wire for input power and control wiring.
• Do not ground the modules in daisy-chain format.
• Keep the ground wire connections as short as possible.
• Follow the wiring requirements in this manual.
• For system modules:
To comply with CE requirements, ensure a minimum ground wire cross-section of at least 16 mm2 (minimum 70 °C, Cu).
To comply with UL requirements, ensure a minimum ground wire cross-section of at least 6 AWG (minimum 60 °C, Cu).
If a PSM 510 module with 10 kW is used, the cable cross-section can be reduced to:
- 10 mm2 (minimum 70 °C, Cu) to comply with CE requirements
- 8 AWG (minimum 60 °C, Cu) to comply with UL requirements

5.4.2 Grounding for EMC-Compliant Installation

• Establish electrical contact between the cable shield and the enclosure using the I/O shielding plate on each module.
