Tables 1:
Recommended Cable Cross-Sections, Cable Lengths and +Fuse Capacities
Configuration of the 3 large capacity terminals
"Com. –", "OUT Board +", "IN Start +":
The central connection point of all minus cables for units
and
batteries
is the
– pole
of the
board
battery
!
As indicated, a
cable "– Batt."
is to be laid separately
between the two negative poles of the battery
–START
and
–Board:
In case of
insulated bodies!
If required, for
relief
of the (lightweight) vehicle chassis for the most powerful unit types.
If a
current measuring shunt
in the minus cable (for instance, of the battery computer) is used, the
central
point
of all minus cables is at the
measuring shunt, but not at the board battery
!
Full charging capacity is ensured, if the
cable cross-sections and cable lengths
are observed according to
the below-mentioned
tables
!
Option: The sensor cables Start IN "
Vs-
and
Vs+
" are often not required, if the below mentioned maximum values for
"
Cable START"
are only used to approx. 3/4 during operating mode
4
according to table 4, page 15.
Option: The sensor cables board OUT "
Vb-
and
Vb+
" are often not required, if the below mentioned maximum values
for "
Cable BOARD"
are only used to approx. 2/3.
