Carefully read through the Operating Instructions before starting any work!
This particularly applies to the General Safety Instructions section
and the safety instructions in the various chapters.
6.7.4 Alternators
For charging the starter batteries, each engine has
an alternator
1 available.
The alternator has been completely wired at the
factory.
This alternator may not be used to charge other
batteries used to power other consumers.
If batteries for supplying other consumers are to be
charged independently of this, a second
alternator
2 (optional) can be mounted.
The two alternators are not double-pole insulated.
In order to ensure isolated (potential-free) wiring,
the entire mounting of the alternators on the en­
gine is isolated. The housing for the alternators is
therefore connected to the negative terminal of the
relevant battery
