X524 Electronics Power Supply; X530 Neutral Point Grounding - Siemens SINAMICS S120 Manual

Voltage Sensing Module VSM10
8.3 Interface description
8.3.6

X524 Electronics power supply

Table 8-6
Type: Spring-loaded terminal 6 (Page 320)
The maximum cable length is 30 m.
Note
The two "+" and "M" terminals are jumpered in the connector. This ensures that the supply
voltage is looped through.
8.3.7

X530 neutral point grounding

Table 8-7
Type: Spring-loaded terminal 5 (Page 320)
The Voltage Sensing Module is supplied with inserted jumper. When delivered, the neutral point
is connected to ground potential via the connector jumper. Current can flow to ground. This
connection is removed by removing the connector jumper. The measurement is then electrically
isolated.
