4.1.2
To protect the Module, we recommend using an external circuit breaker, a TVS diode, and a capacitor in
the voltage supply cable. In this regard, please note the following recommendations:

NPUT
An input fuse (FU1) is necessary in order to provide reverse polarity protection. Together with an unipo-
lar TVS diode (D1), this prevents current from flowing in the wrong direction.
TVS D
To protect against overvoltage resulting from voltage transients or brake energy feedback, we recom-
mend connecting a TVS (transient voltage suppressor) diode (D1) to the voltage supply line.
C
APACITOR
The function of the Module does not necessarily require the use of an external capacitor. Nevertheless,
to further reduce voltage ripple and feedback currents, an electrolytic capacitor (C1) can be connected
to the voltage supply line. Use of an electrolytic capacitor is also recommended to avoid oscillations
caused by supply cable inductance or Module's built-in capacitors that could lead to a voltage overshoot
at power plug-in.
