1.10 Special hazards
In the following section the residual risks are listed. Regard the listed safety warnings
here and the notes in the whole manual to reduce health hazards and to avoid dangerous
situations.
DANGER
Risk of death by electric current!
Contact with live parts is immediate danger to life. Damage of the insulation or
of components can be danger to life.
Therefore: Immediately turn off the power supply when the insulation is damaged. Work
on the electrical system only by qualified personnel. Always power-of
f and secure the
electrical system during the work on it.
DANGER
Risk of death by electric current!
After disconnecting a device from main voltage, parts such as power con-
nections should only be touched when the capacitors are discharged in the
device.
Therefore: Regard discharge time of the capacitors, do not touch live parts before.
Regard corresponding instructions on the device. If you have connected additional capac-
itors on the link, the discharge of the link can last considerably longer
. In this case you
have to determine the required waiting period or even to measure whether the device is
free of voltage.
WARNING
Risk of injury from moving parts!
Rotary respectively linear moved parts can cause serious injuries.
Therefore: Do not touch moving parts during operation. Do not open the cover during
operation. The mechanical residual energy depends on the application. Driven compo-
nents rotate respectively move for a certain time even after switching of
f the power
supply. Here serve for suited safety devices.
