into the electric installation (con-
nection of other electric appli-
ances) are permissible due to its
possible overloading!
54. The values of the electric installation
are:
Nominal voltage 12 V =

Using starting trucks or auxiliary power
supplies with a different voltage or polar-

pay increased attention and avoid short-

a battery disconnector. Switch it off when
handling the battery.
