.
4.
When supplied from an isolated line power
source (IT line power or floating delta) or TT/TN-S
line power with a grounded leg (grounded delta),
ensure that the RFI filter screw is removed to
avoid damage to the intermediate circuit and
reduce ground capacity currents in accordance
with IEC 61800-3.
