Maintenance information

The supplied power unit is free of maintenance.

Prohibition of unauthorized modifications

For safety reasons, you must not modify or add components on/to the drive.

WARNING

This power unit carries dangerous voltage and contains dangerous rotating parts (fans). Ignoring the
safety and warning information may result in death, severe personal injury or damage to material
assets.

All maintenance and service work must only be carried out when the unit is de-energized.

Do not begin work on the DC link of the power unit until you have made sure that neither potential nor
voltage (residual charge) is applied.

When dismantling safety equipment during commissioning, repair and maintenance, ensure that the
machine is take out of commission in accordance with applicable regulations. Remount and check the
safety equipment immediately after completing commissioning, repair and maintenance work.

After carrying out any work on the machine –regardless of whether this involves the motor, the actual
value detection or the power unit – the owner must carry out acceptance testing of the entire drive and
document this chronologically in the machine log.

Failure to do this may result in the owner being faced with consequences relating to liability.
