General safety instructions
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 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
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
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
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational readiness in the inverse sequence.
Electric shock due to connection to an unsuitable power supply
When equipment is connected to an unsuitable power supply, exposed components may carry
a hazardous voltage. Contact with hazardous voltage can result in severe injury or death.
• Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV- (Protective
