Power supply
CAUTION
An excessive charging current poses a
cable fire hazard!
If the tail lift is operated while the vehicle
motor is running, the charging current may
be too high and cause the cable to catch
fire.
► Turn off the tractor unit's motor while
operating the tail lift.
NOTE
Unsuitable charging cables pose a fire
hazard and may cause material dam-
age!
Unsuitable charging cables may tear or
break and cause fires.
► Only use coiled flex cables.
► Also observe the enclosed supplier
documentation.
The tail lift is supplied with power either
○
via an auxiliary battery or
○
via direct supply from the tractor unit.
Auxiliary battery
Two 12V batteries in the trailer supply the
tail lift with power. The electric charging
cable is connected to the tractor unit's plug
and must remain connected while driving.
The battery is charged when the motor of
the tractor unit is running and the voltage is
greater than 26.4 V. The battery is not
charged when the motor of the tractor unit
is not running and the voltage falls below
25.6 V. The battery is not charged when
the tail lift is actuated.
Direct supply
The tractor unit's batteries directly supply
the tail lift with current. The electric char-
ging cable is connected to the tractor unit's
plug and must remain connected while
driving.
