Systems that are still running! Risk of injury! The work
WARNING
steps described in this chapter may only be performed
on shut down systems. IMPORTANT: Even after the
servo-hydraulic actuator was disconnected from the elec-
trical power supply the system is still under pressure!
Before beginning work:
−
Make sure that the drive motor cannot be switched
on.
−
Ensure that all force-transmitting components and
connections are (electrically) switched off and
secured against restarting according to the manufac-
turer's instructions. If possible, remove the main fuse
of the system. Verify with the help of inspected meas-
uring equipment that there is no voltage applied.

of injury! Severe injury when working on systems that
have not been shut down! Damage to property!
−
Observe the specifications of the system manufac-
turer and the system end-user.
−
Do not disconnect line connections, ports or compo-
nents as long as the servo-hydraulic actuator is pres-
surized.
−
The hydraulic circuit may only be opened by specifi-
cally trained personnel.

avoid injuries when working on electrical systems you
should take the following precautions in the order listed:
−
Disconnect completely
−
Secure against re-connection. Observe the discharge
time of the converters!
−
Verify that the installation is dead
−
Carry out earthing and short-circuiting
−
Cover or shield against adjacent live parts
