Siemens SINAMICS - X530 Neutral Point Grounding

The maximum cable length that can be connected is 30 m.
Note
The two "+" and "M" terminals are jumpered in the connector. This ensures that the supply
voltage is looped through.

Terminal Designation Technical data
1 Neutral point of the voltage
sensing
Jumper inserted: Grounded measure‐
ment
Jumper not inserted: isolated measure‐
ment
2 Ground potential
Type: Spring-loaded terminal 5
The Voltage Sensing Module is supplied with inserted jumper. When delivered, the neutral
point is connected to the protective conductor via the connector jumper. Current can flow to PE.
This connection is removed by removing the connector jumper. The measurement is then
electrically isolated.
