6. Follow safety measures in the filter installation.
• Ensure that the protective earth terminal (PE) of the filter is properly connected to the PE
terminal of the adjustable frequency inverter. An HF ground connection via metal
contact between the housings of the filter and the adjustable frequency inverter, or solely
via cable shield, is not permitted as a protective conductor connection. The filter must be
solidly and permanently connected with the ground potential so as to preclude the danger
of electric shock upon touching the filter if a fault occurs.
To achieve a protective ground connection for the filter:
• Ground the filter with a conductor of at least 10 mm
• Connect a second grounding conductor, using a separate grounding terminal parallel to
the protective conductor. (The cross section of each single protective conductor terminal
must be sized for the required nominal load.)
