8.3 POWER SUPPLY
This board supplies all other boards taking energy from A08 board and from DC voltage when rectifier is on. So it can
supply the boards in case of input line black out.

8.5 FUSES BOARD
REPLACING THE FUSES
CAUTION! : ALL CONNECTING PROCEDURES DESCRIBED IN THIS CHAPTER MUST
BE CARRIED OUT BY AUTHORIZED ELECTRICIANS OR BY QUALIFIED
TECHNICIANS
.
CAUTION! : BEFORE REPLACING THE FUSES YOU MUST CARRY OUT THE MANUAL
BY-PASS PROCEDURE WITH THE U.P.S. DISCONNECTED (CHAPTER 5)
A nut screw fastens each fuse. When replacing a fuse you must unscrew the two knurled nuts corresponding to the
fuse, which must be replaced, remove the washers, replace the fuse and put back the washers and the knurled nut in this
order. The fuses used are extra-fast fuses for the current specified in charts 9a and 9b.
If you replace fuses with models different to the above described the guarantee will no longer be valid
.
8.6 STATIC DRIVER
Static switch is made by SCR, this board drives them.
