Fire and device damage as a result of ground fault/short-circuit
Inadequate installation of the cables to the Motor 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:
NOTICE
Damage to the dV/dt filter compact due to mechanical load on connections
The connections at the dV/dt filter compact are not designed for direct mechanical
connection to the motor cables.
• Take measures on the plant or system side to ensure that the connections cannot be
