8. 8. 8. 8. Follow safety measures in the filter installation.
• • • • If using external EMC filter, ensure that the ground terminal (PE) of the filter
is properly connected to the ground 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.)
