DANGER
Danger to life from stored charges!
Electric charges may be stored in electrical components even after the system has
been switched off and disconnected from the power supply. Contact with these com-
ponents may result in serious or fatal injury.

pletely disconnected from the power supply. Allow 10 minutes to elapse in order to
ensure that the internal capacitors have been fully discharged.
WARNING
Danger of injury due to movements caused by stored pneumatic forces!
Pneumatically driven components may move unexpectedly due to stored residual
forces, causing serious injuries.
f Work on the pneumatics system must only be carried out by trained pneumatics
technicians.
f Before starting work on the pneumatics system, ensure that it has been com-
pletely depressurized. The pressure accumulator must be completely relieved.
