Permitted voltage supply systems
- INFORMATION
- Voltage supply systems with grounded star point
- MOVITRAC® B is intended for operation on TN and TT systems with directly grounded star point.
- Voltage supply systems with non-grounded star point
- For operation on voltage supply systems with non-grounded star point (IT system), SEW-EURODRIVE recommends using an insulation monitoring device that can drive capacitive loads. Using such devices prevents the earth-leakage monitor from mis-tripping due to the ground capacitance of the inverter.
- Supply systems grounded via an outer conductor
- Operate the inverters only on supply systems with a maximum line-to-ground voltage of AC 300 V.
