2.2 Meaning of Safety Signs
The operating instructions use the following safety signs which you will also find on equipment. Their
meaning is described shortly in order to give you an idea of the importance and the specific aspects to
be aware of.
HIGH VOLTAGE!
In case that the equipment is in use, dangerous voltages are present. Touching
live parts of devices energised with these voltages will result severe injuries or
even death. Appropriate actions must be taken. Before starting to work, observe
the following safety rules:
1. Switch off the equipment, disconnect the equipment from the mains
supply.
2. Take precautions against inadvertent re-connection.
3. To verify that circuits are dead and no voltage is present perform the
appropriate measurements.
4. Ground and short-circuit.
5. Cover live parts in the proximity or otherwise protect them against
touching.
The dangerous voltages are no longer present.
Voltage may only be applied to components being worked on when this is
expressly prescribed (e.g. during troubleshooting). Mains switches are live even
when the equipment is switched off. During work always observe the relevant
regulations for the prevention of accidents, e.g. German VBG 4, or EN 292. Only
use suitable, intact tools and measuring instruments!
DANGER! WORK IN PROGRESS! DO NOT SWITCH!
The switch(es) marked with this sign must never be operated.
Severe injuries or even death can occur as consequence of disregard.
The sign will have amendments like the name of the person who has marked the
switch(es) and time/date of mounting of the sign.
Only the person stated on the sign may remove the sign and operate the
switch(es).
TURNING DEVICES!
Marked devices or devices in the vicinity of this sign may start turning automati-
cally if the equipment is in use. Always switch off the respective equipment or
drives of the devices. Take precautions to prevent inadvertent reactivation of the
devices before you start to work on the devices.
