Safety instructions
To protect you from electrical shocks, injury or burns
the following basic safety principles must be observed
when using electrical devices. Please read and follow these
instructions before using the device.
Installation
Ensure that the devices are positioned safely and cannot fall
down or over. Always position the cables to ensure they do
not pose a tripping hazard. Do not expose electrical devices to
rain. Do not operate electrical devices in damp or wet environ-
ments. Do not operate electrical devices close to flammable
liquids or gases.
Protection against an electrical shock
Only operate devices whose casings and cables are undam-
aged. Ensure the cables are installed safely. Do not pull on
the cables.
Only operate the device if it has been secured with a
30 mA fault-current circuit breaker. The valid local
installation regulations must be observed.
Use
During use, please observe the regulations of EN 60335-1: 2010,
according to which this device has not been designed for use
by people (including children) who have restricted physical,
sensory or mental abilities or a lack of experience and / or
knowledge, unless they are supervised by a person respon-
sible for their safety or have received instructions from that
person as to how the device is to be used.
Children should be supervised to ensure they do not play with
the device.
Do not use electrical devices for purposes other than those
stated by the manufacturer. The ventilation slits in the housing
must be free and may not be covered by luggage, towels or
clothing etc.
Before connecting or disconnecting cables, ensure that the
power supply has been interrupted! Pull out the mains plug
and disconnect the batteries.
Mains supply mode on ferries
The main supply voltage on ferries can be prone to heavy
fluctuations. Therefore, do not connect this device with this
voltage without adequate protection.

Generator mode
Please observe the handling instructions in the manufacturer's
operating instructions. The generator must satisfy the 230 V
mains power connection values. The generator must comply
with the 230 V mains connection values. Only operate the
device on a generator that runs steady. The voltage peaks that
occur during the start-up and shut-down phase (e.g. due to a
lack of fuel) can damage the device.
Repairs
Do not repair or modify the device. Please contact your dealer
or the Truma Service (see service manual or www.truma.com).
Accessories
Only use accessories and additional devices that are supplied
or recommended by the manufacturer.
Application purpose
The charging device only serves to charge 12 V lead
accumulators comprising 6 single cells (e.g. car battery) with
a capacity of 70 – 200 Ah – Smart Charge 20 (100 – 300 Ah –
Smart Charge 30). It can be used universally and is designed
for continuous use or parallel mode. This automatic charger
has been designed to work best with gel, AGM or liquid elec-
trolyte batteries. The device is designed for installation in cara-
vans, campers and boats.
Improper use
The device is not suitable for charging
– 6 V batteries or 6 V lead accumulators
– non-chargeable batteries
– nickel-cadmium batteries.
If batteries with a rated voltage of 6 V are charged with the
device, gassing occurs immediately. An explosive gas can
be created.
Battery care
(also maintenance-free batteries)
The following points should be observed to extend the
battery life:
– Batteries should be fully charged before and after they have
been used,
– disconnect from the power circuit in the case of longer
standstills (e.g. with a circuit-breaker or by disconnecting
the battery terminal),
– in the case of longer standstill periods, the battery must be
disconnected and charged for 24 hours at the latest every
12 weeks.
Store fully charged batteries in a cool but frost-free place
during the winter and recharge regularly (every 12 weeks).
Description
The automatic charger contains state-of-the-art microproces-
sor-controlled charging technology. The automatic charging
process is gentle to the battery and prevents damaging over-
charging, which in turn significantly extends the service life of
the battery. After the battery and mains supply have been con-
nected, the automatic charger is ready for use.
The automatic charger is designed for continuous operation
and parallel mode. Consumers can be continuously connect-
ed, switched on or disconnected. Consumers are supplied and
the battery charged at the same time. The consumer current
here should be smaller than the maximum charging current as
otherwise the battery will not charge.
The device may not be left connected to the battery with-
out solar or mains power for longer than two weeks.
