8.1.8 Dimensional criteria of the power supply cables
For the supply cables respect the following
provisions:
• Cables from the battery to engine starter
(both positive and negative poles) must
have a minimum cross section of 50 mm
2
, if
it is not specified a higher cross section by
the engine supplier.
• The GND of the actuator must be connected
directly to the negative pole of the battery.
Minimum cross section is 2,5 mm
2
.
• In case electronic throttle, it is very impor-
tant to connect to a common GND point
(either GND bus bar or common bonding
conductor or hull) all the negative poles of
each electronic device.
