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
