For assembling and maintaining the system, the relevant DIN, VDE, EN and IEC regulations
, as well as all national and local safety and accident prevention regulations must always
be observed. The system manufacturer or the user is responsible for ensuring that these

Warning
Vertical axes must be additionally secured against falling or
sliding down when the motor is switched off with e.g.
- mechanical locking of the vertical axis,
- external braking, safety catch or clamping devices or
- sufficient weight compensation of the axis.
Warning
The series-supplied motor holding brake or an external motor-
holding brake controlled by the drive controller alone is not
suitable for protecting human beings.
Warning
Switch the electrical equipment free of voltage via the main switch
and make sure that it cannot be switched on again. Wait until the
intermediate circuit is discharged after
- maintenance work and repairs
- cleaning
- long periods out of use.
