* Due to the direct connection to the output, the demagnetizing varistor is also effective at the
input (see figure) above. This is why the difference between UPx and the input signal must not
exceed the clamp voltage of the varistor. The varistor limits the clamp voltage to approx. 36 V.
Consequently, the input voltage must range from -12 V to +30 V when UPx = 24 V and from
-6 V to +30 V when UPx = 30 V.
