RFI Filter Grounding
!
ATTENTION: Using an optional RFI filter may result in relatively high
ground leakage currents. Therefore, the filter must only be used in
installations with grounded AC supply systems and 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. Failure to observe this
precaution could result in damage to equipment, severe bodily injury or
loss of life.
