For all
installations above 30V high-voltage, adaptors must be used. We have now
recommend a second 24V, 1W protection zener in the Hi-V adaptation (see Fig. 6
of Technical Data). This diode should be placed from the input of the Music
Rail to J1. This is in addition to the diode connected from the input to
J12.
