Smart Line Modules
When the device is operated on an isolated line supply (IT line supply), the connection bar to
the interference suppression capacitor must be removed (e.g.: "1" in figure below).
With frame sizes HX and JX, you must remove the left-hand fan before removing the
connection bar (see chapter "Replacing components").
