Troubleshooting
Error
Rectification
The battery does not charge. Check all connections from
the automatic charger to
the battery, ensure that they
are connected to the right
terminals. Unplug the cold
device plug on the device
then plug in again. Check all
fuses and the mains supply
connection.
The maximum charging
current is not reached.
The device is too warm,
ensure better ventilation of
the device.
If these measures do not solve the problem, please
contact the Truma Service Centre.
Maintenance
The power supply must always be disconnected before
performing any maintenance work on the device.
Clean the device and the ventilation slits with a dry and fluff-
free cloth.
Disposal
The device must be disposed of in line with the administra-
tive regulations of the respective land in which it is used.
National regulations and laws (in Germany, for example,
the Altfahrzeug-Verordnung [old vehicle directive]) must be
observed.
Technical Data
Power supply
AC voltage 230 V / 50 Hz, single-phase
Range approx. 97 V – 250 V / 50 – 60 Hz
Output current (charging current battery)
Charging current max. 60 A, arithmetic mean value, electroni-
cally controlled according to the IUoU charging reference line.
Distributed over outputs 1…3, depending on the charge sta-
tus of the connected batteries.
Output voltage
DC voltage 12 V
Charging process
Automatic
Automatic switching (main charging process)
OFF at a battery voltage of 14.4 V, charging current < 54 A
Automatic switching (afterloading phase)
10 hours constant 14.4 V for gel batteries / AGM.
4 hours constant 14.4 V for liquid electrolyte batteries.
Automatic switching (trickle charging)
Trickle charging constant 13.8 V
Temperature-dependent control (optional)
The values of the automatic switching device refer to a battery
temperature of 20 °C. If a temperature sensor is used with the
battery I, these values will vary in accordance with the battery
temperature.
High temperature –> reduction of the threshold values.
Lower temperature –> higher threshold values.
Application
Parallel mode, general charging mode.
Temperature
Ambient temperature from -25 °C to +50 °C.
During operation, the casing may heat up to around 75 °C.
Cooling
By temperature-controlled ventilator.
Configuration
In accordance with the VDE provisions and the device
safety law.
Use
To charge the batteries with 12 V rated voltage and a capacity
of 200 – 600 Ah.
