Risk of electric shock if the unit is opened.
BSS Audio accepts no responsibility for injury
subsequent to opening of the unit.
The primary of the mains transformer within the FDS-388 is protected against
high voltage spike interference by two voltage dependent resistors. These
provide a short circuit to voltage peaks in excess of their maximum rating.
Should the FDS-388 be inadvertently connected to 3 phase line/line voltages,
or to 240V when selected to 120V, or any other incorrect voltage, these
suppressors are likely to fail in a protective short circuit mode. This will be
demonstrated by repeated mains fuse failure when powering up the unit.
Figure 22.1 indicates the location and specification for the suppressors.
