4.3 VSM pre-selection module
The VSM pre-selection module electrically isolates the mains voltage
signals of the drive circuit and the safety circuit from the control signals of
the FST-Controller. The control signals of the drive are isolated by the pre-
selection relays. The control signals of the safety circuit are isolated by the
opto-coupler.
The zero conductor of the drive contactors must be routed via the
circuit board (see terminals X1.8 and X2.9 on page 52 for connecting the
zero conductor).
A valid type verification certificate from the TÜV-Rheinland is available for
the VSM pre-selection module.
