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.
