Work on electrical systems or equipment may only be carried out by an
electrical specialist or by instructed persons under the direction and supervision
of an electrical specialist in accordance with the electrotechnical rules.
•
People with pacemakers are not allowed to enter the control cabinet areas!
•
Plant components on which inspection, maintenance and repair work is carried
out must - if prescribed - be switched voltage-free. First check the unlocked
parts for freedom from tension, then ground and short-circuit as well as isolate
adjacent parts under tension!
•
Use only original fuses with prescribed current! In the event of disturbances in
the electrical power supply, switch off the system immediately!
•
Inspect or check the electrical equipment of the system regularly. Eliminate
defects, such as loose connections, damaged or brittle cables, etc. immediately.
•
If work on voltage-carrying parts is necessary, then call in a second person
who, in an emergency, operates the emergency stop or the main switch with
voltage release. Lock off the work area with a red and white safety chain and a
warning sign. Use only voltage-insulated tools!
NOTE:
Please note the special safety instructions in the individual chapters!
