Risk of fire and damage to equipment due to short-circuit / ground fault
The cables to the DC link of the Motor Modules must be routed so that a ground fault or
short-circuit can be ruled out. A ground fault can result in fire with smoke.
• Protect the cables from mechanical damage.
• Comply with local installation regulations that enable this fault to be ruled out.
In addition, apply one of the following measures:
• Use cables with double insulation.
• Maintain adequate clearance, using spacers, for example.
• Route the cables in separate cable ducts or pipes.
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.
