General safety instructions
WARNING
Electric shock and danger to life due to other energy sources
Touching live components can result in death or severe injury.
• Only work on electrical devices when you are qualified for this job.
• Always observe the country-specific safety rules.
Generally, the following six steps apply when establishing safety:
1. Prepare for disconnection. Notify all those who will be affected by the procedure.
2. Isolate the drive system from the power supply and take measures to prevent it being
switched back on again.
3. Wait until the discharge time specified on the warning labels has elapsed.
4. Check that there is no voltage between any of the power connections, and between any
of the power connections and the protective conductor connection.
5. Check whether the existing auxiliary supply circuits are de-energized.
6. Ensure that the motors cannot move.
7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or
water. Switch the energy sources to a safe state.
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational readiness in the inverse
sequence.
WARNING
Electric shock due to damaged motors or devices
Improper handling of motors or devices can damage them.
Hazardous voltages can be present at the enclosure or at exposed components on
