RFI Filter Grounding
Important: Using the optional RFI filter may result in relatively
high ground leakage currents. Surge suppression
devices are also incorporated into the filter. Therefore,
the filter must be permanently installed and solidly
grounded (bonded) to the building power distribution
ground. Ensure that the incoming supply neutral is
solidly connected (bonded) to the same building power
distribution ground.
Grounding must not rely on flexible cables and should
not include any form of plug or socket that would
permit inadvertent disconnection. Some local codes
may require redundant ground connections. The
integrity of all connections should be periodically
checked.
