comply with UL requirements, ensure a minimum ground wire cross-section of 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 mm
with CE requirements and 8 AWG (minimum 60 °C, Cu) to comply with UL requirements.
• Keep the ground wire connections as short as possible.
• Follow the wiring requirements in the VLT® Multiaxis Servo Drive System MSD 510 Operating Guide.
