according to ETS 300132-2, version 4.3 (40IMX4).
Inrush Current
The inrush current has been kept as low as possible by
choosing a very small input capacitance. A series resistor may
be inserted in the input line to further limit this current.

Filter to Comply with EN 55011/55022
Electromagnetic emission requirements according to table
Electrical Input Data can be achieved by adding an external
capacitor as close as possible to the input terminals (see fig. 7
and table 3).
