Risk of fire and damage to equipment due to short-circuit / ground fault
The cables to the filter module must be routed so that a ground fault or short-circuit can be
ruled out. A ground fault can result in fire with associated 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, e.g. using spacers.
• Route the cables in separate cable ducts or pipes.
Operating an Active Interface Module on a non-grounded line supply (IT system)
When the device is operated on a non-grounded line supply (IT system), the integrated basic
interference suppression modules must be deactivated by removing a connection clip.
Note
Warning label on the connection clip
A yellow warning label is attached to each connection clip so that it is easier to find.
• The warning label must be removed from the connection clip (by pulling it off) if the
connection clip is to remain in the unit (operation on a grounded line supply).
• The warning label must be removed together with the connection clip if the unit is
operated on a non-grounded line supply (IT system).
