X530 neutral point grounding

Table 2- 25
The Voltage Sensing Module is supplied with inserted jumper. When delivered, the neutral
point is connected to the protective conductor via the connector jumper. A current flows to
PE as a result of the voltage to be measured. This connection is removed by removing the
connector jumper. The measurement is then electrically isolated.
