General safety instructions
DANGER
Danger to life due to live parts and other energy sources
Death or serious injury can result when live parts are touched.
•
Only work on electrical devices when you are qualified for this job.
•
Always observe the country-specific safety rules.
Generally, six steps apply when establishing safety:
1.
Prepare for shutdown and notify all those who will be affected by the procedure.
2.
Disconnect the machine from the supply.
–
Switch off the machine.
–
Wait until the discharge time specified on the warning labels has elapsed.
–
Check that it really is in a no-voltage condition, from phase conductor to phase
conductor and phase conductor to protective conductor.
–
Check whether the existing auxiliary supply circuits are de-energized.
–
Ensure that the motors cannot move.
3.
Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or
water.
4.
Isolate or neutralize all hazardous energy sources by closing switches, grounding or
short-circuiting or closing valves, for example.
5.
Secure the energy sources against switching on again.
6.
Ensure that the correct machine is completely interlocked.
After you have completed the work, restore the operational readiness in the inverse
sequence.
WARNING
Danger to life through a hazardous voltage when connecting an unsuitable power supply
Touching live components can result in death or severe injury.
•
Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV-
(Protective Extra Low Voltage) output voltages for all connections and terminals of the
electronics modules.
