Reverse Polarity Protection
The built-in suppressor diode also provides for reverse polarity
protection at the input by conducting current in the reverse
direction. An external fuse is required to limit this current.

Inrush Current
The inrush current has been kept as low as possible by
choosing a very small input capacitance. A series resistor may
be installed in the input line in order to further reduce this
current.

Example for external circuitry to comply with IEC/EN 61000-
4-5; the diode D is only necessary for 20IMX35 models.
For very high energy transients as for example to achieve
IEC/EN 61000-4-5 compliance (as per table Electromagnetic
Immunity) an external inductor and capacitor are required. The
components should have similar characteristics as listed in
table below.

Input Transient Voltage Protection
A built-in suppressor diode provides effective protection
against input transients, which may be generated for example
by short-circuits across the input lines, where the network
inductance may cause high energy pulses.
