Remark:
De-nude cable ends only:
- Signal cable 0.75 – 1.5 mm

: 9 mm
- Charging cables – 12 mm
Don’t use bootlace ferrules!
Option:
Cable length and cross-
sections see table 1
Cable length 50 cm each
and cross-sections**
NOTE:
Fusing protects cabling
against fire! Therefore allways
install close to battery.

Adapt cross-section on biggest load
(e.g. inverter) as well
F I and F II > 100 A
Optionally use cherging cable set 2 – 6 m
with cable lugs and 250 A fusing.

Installation type 4 – Special case: power consumption while driving more important
than charging capacity of the BCB
For operating conditions when sometimes higher currents are drawn than the BCB can supply will
need to flow to the board battery.
