Risk of fire due to ground fault / short-circuit
Inadequate installation of the cables to the Power Module or 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:
Note
Maximum cable lengths
The connections should be kept as short as possible.
The maximum cable length for the specified connections is 5 m in each case.
