* The external power pack at this interface is connected in parallel to the internal 24V power supply. The
internal isolating diode ensures that with equally high supply voltages (internal = external), the internal
power supply bears the load. The power pack must be stabilized and protected against short circuits and
overloads. Maximum ripple voltage 240 mV

.
More boundary conditions for emergency stop on the user side:
• When an emergency OFF is triggered (mains supply interrupted), the external 24V supply must not
be switched off as otherwise data may be lost.
• The external 24V supply may not be generally switched in order to avoid high starting currents (on
the secondary side).
• When an emergency OFF is triggered (mains supply interrupted), no CW/CCW should be set, as
this can lead to system errors.
• The maximum line length between power pack and VM350 must not exceed 5 m.
• Triggering the emergency OFF (mains switching) is subject to the same time intervals as switching
on the mains. After the return of the mains power supply, wait approx. 10 s before setting CW/ CCW.

Shutdown is effected via
the mains lead and must be
realized by the customer.
The user must ensure that the boundary conditions for emergency stop according to EN ISO 13849 are
satisfied.
