8.11.2 Mains Synchronization HMV01
The synchronizing voltage has to be picked off before the mains choke and
after the mains filter. Power voltage and synchronizing voltage connection have
to be in phase (see figure).
The synchronizing voltage has to be connected to the input for mains voltage
synchronization (X14) of the supply unit.
