Safety notes

1.1

Electric shock and danger to life due to other energy sources

Touching live components can result in death or serious injury.

• Only work on electrical equipment if you are appropriately qualified.

• Always observe the country-specific safety rules for all work.

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 that every auxiliary circuit is 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 by following the

above steps in the reverse order.
