Requirements for flawless operation of the rectifier-regulator
-
body of regulator must be grounded with no restance allowed
-
the rectifier-regulator has to be protected by a slow blowing 25A
fuse.
-
wire size of the main circuit of at least 2,5 mm
2
(14 AWG)
-
a capacitor (Fig. 67 Pos. (25)) of at least 22 000 μF / 25 V is
necessary to protect the correct function of regulator and to flatten
voltage. The regulator is not designed to store any electrical charge.
If for any reason the battery or bus system is disconnected from the
regulator while the engine is running (i.e. the master switch is shut
off) the capacitor will safely absorb and dissipate the electrical
charge produced by the generator. Otherwise the regulator would
be damaged.
■
CAUTION:
The voltage difference between battery and terminal
C
of regulator should be less than 0,2 V.
Use cables in this area as short as possible and with
adequate cross section.
■
CAUTION:
Never sever connection between terminal
C
and
+B
of
regulator (e.g. by removal of a fuse) while the engine
is running. Overvoltage and regulator damage can
occur.
