*) 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 may
not exceed the clamp voltage of the varistor. The varistor limits the voltage to approx. 36 V.
Following this, 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.
