Risk of fire due to ground fault/short-circuit

Inadequate installation of the cables to the Power Module DC link can result in a ground

fault/short-circuit and place persons at risk as a result of the associated smoke and fire.

• Comply with local installation regulations that enable this fault to be ruled out.

• Protect the cables from mechanical damage.

• In addition, apply one of the following measures:

Damage to the dv/dt filter compact due to mechanical load on connections

The connections on the dv/dt filter compact have not been designed for the direct

mechanical connection of the motor cables.

• Take line-side measures to ensure that the connections cannot be deformed by the
