X522 three-phase line supply voltage sensing up to 690 V (phase-to-phase)

Table 4- 5
Max. connectable cross-section: 6 mm²
NOTICE
Destruction of the VSM10 as a result of a terminal assignment which is not permissible
The VSM10 has two terminal strips, X521 and X522, to sense the three-phase line supply
voltage. A terminal assignment which is not permissible results in the module being
destroyed.
• Use just one of the two terminal strips.
• Only connect voltages to terminal strip X521 up to a maximum 100 V (phase-to-phase)
• Only connect voltages to terminal strip X522 up to a maximum 690 V (phase-to-phase)
Note
Connection sequence
The phases must be connected to the VSM10 with the same sequence as that of the Power
Module.

X530 neutral point grounding

Table 4- 6
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.
