"Active ventilation" option: The drive battery
can be charged using an external battery
charger even when the battery hood is closed,
via a battery female connector (1) and a
venting device (2) fitted in the rear area.
Active ventilation ensur
es that the gases
produced during the charg
ing process when
the battery hood is closed
are extracted from
the truck.
DANGER
Risk of explosion! The escaping gases are flamma-
ble.
Only charge the battery in well-ventilated areas.
There must be no objects or obstructions in the
immediate vicinity of the fans. During charging,
ensure sufficient ventilation for the charge gases to
escape.
CAUTION
Battery still releases gas once charging is complete
The rear cover must be kept open during the char-
ging process and also during the fan run-on time to
ensure that all remaining gases can escape from
the battery compartment.
NOTE
Check fan for contamination and clean as
required. The function of the fan must be
checked during each charging process.
Malfunctioning or faulty fans must be replaced
immediately. Contact your service partner.
NOTE
The plug for the external battery charger must
be equipped with auxiliary contacts that are
connected to each other via a jumper. This
is required to start the charging process.
Contact your service partner.
