Caution
If the operating voltage is switched off while the com-
pressed air supply is still switched on, the actuators may
be triggered, resulting in unexpected movements which
may cause damage. Switch off the operating voltage and
the compressed air supply at the same time or in the fol-
lowing sequence:
1. compressed air supply
2. operating voltage
Please note
Make sure that the compressed air supply and the operat-
ing voltage are switched off before starting installation and
maintenance work.
General rules for building up the system can be found in the
