2 Introduction
This instruction manual contains important information for safe operation of
the device. Make sure you read and follow the safety instructions provided.
The instruction manual should always be kept in the vehicle. All safety infor-
mation must be passed on to other users.
3 Operation
The electroblock is operated solely via the IT ... / LT ... control and switch
panel connected. .
Operation of the EBL 271 electroblock is not required in daily use.
Settings only have to be configured once when the battery type is changed
(lead-acid or lead-gel), during initial start-up or when retrofitting accessories
(see Section 3.2 and the installation instructions for the EBL 271).
3.1 Starting up the system
Y ATTENTION!
Incorrect electroblock settings can result in damage to connected devices.
Therefore prior to starting:
F Ensure the living area battery is connected.
F Ensure that the battery selector switch (Fig. 3, Pos. 9) is set to the
correct position for the battery installed.
Use the main 12V switch (see instruction manual for relevant control and
switch panel) to switch on/off all the consumers and the control and switch
panel.
Outputs are exceptions:
F Car radio
F Heater
F Refrigerator controller
F Step
F Awning light
F TV
These outputs are not disabled via the main switch of the IT ... /LT ... control
and display panel.
Please refer to the operating instructions for the IT ... /LT... control and
switch panel for further information. .

Y ATTENTION!
The electroblock, 12V consumers and the connected devices can be da-
maged if the thresholds for the 230V supply are exceeded. Note therefore
the following:
F It is essential that the generator conforms to the specifications of the
mains supply.
F Do not connect the generator until it is running smoothly.
F Do not connect the electroblock to the mains supply on board passen-
ger vehicle ferries (a correct mains supply is not always guaranteed
on board these ferries).
3.2 Changing the battery
Y ATTENTION!
Using incorrect battery types or incorrectly designed batteries results in
damage to the battery or devices connected to the electroblock. So there-
fore:
F Batteries should only be changed by qualified personnel.
F Follow the battery manufacturer’s instructions.
F Only connect the electroblock to 12V power supplies with rechargea-
ble 6-cell lead gel or lead acid batteries. Do not use any unsuitable
battery types.
Y Normally only batteries of the same type and capacity should be used,
i.e. the same as those installed by the manufacturer.
Y It is possible to swap lead acid batteries with lead gel batteries. However,
swapping from lead-gel batteries to lead-acid batteries is only possible in
certain cases. Contact the vehicle manufacturer for more information.
" Electrically disconnect the battery from the electroblock. To do this, ena-
ble battery isolation on the IT .../LT .... control and switch panel (see also
Section 3.1).
" Replace battery.
" After changing the battery, recheck which type of battery has been inser-
ted.
Y DANGER!
Incorrectly setting the battery selector switch poses a risk of explosion due
to the formation of detonating gas. So therefore:
F Move the battery selector switch to the correct position.
" Disconnect the electroblock from the mains before adjusting the battery
selector switch.

Fig. 1 Battery selector switch
"
Move the battery selector switch (Fig. 1, Pos. 1) into the correct position:
F Lead gel battery: Move the battery selector switch to ”Lead-gel”.
F Lead acid battery: Move the battery selector switch to ”Lead-acid”.
F AGM battery: Schaudt GmbH recommends charging AGM batteries
with their chargers in switch position ”Lead-gel battery”.
We believe that AGM batteries can be charged perfectly this way. Ho-
wever, suitability must be checked using information from the battery
supplier and the charging parameters of Schaudt equipment. The
charging parameters are specified in the operating and installation
instructions.
" Start up the system as described in Section 3.1.
3.3 Faults
A fault in the power supply system is usually caused by a blown fuse.
Please contact our customer service department if you cannot rectify the
fault using the following table.
If this is not possible, e.g. if you are abroad, you can have the electroblock
repaired at a specialist workshop. In this case you must ensure that the war-
ranty is not invalidated by incorrect repairs being carried out and Schaudt
GmbH will not accept any liability for damage resulting from such repairs.
The following functions are protected by a polyswitch fuse:
F 12V indicator
F Battery 1
F Output D+
F Marker lights
If there is a fault here, the cause of the overload must be rectified. After-
wards, the relevant supply circuit must be interrupted for a period of about 1
minute (e.g. by removing the relevant connector, see block diagram on Page
14). The polyswitch fuses are reset automatically during this period.

Y The charging current is reduced automatically if the device becomes too
hot due to excessive ambient temperature or lack of ventilation. Always
prevent the device from overheating nevertheless.
Y If the automatic shutdown mechanism of the battery monitor is triggered,
fully charge the living area battery.
3.4 Closing down the system
A battery is isolated by switching off the main switch on the IT .../LT ... con-
trol and switch panel and by disconnecting a plug connector.
Y ATTENTION!
Damage to the living area battery as a result of total discharge. So therefore:
F Fully charge the living area battery before and after closing down the
system. (Connect vehicle to the mains with an 80Ah battery at least
12 hours and with a 160Ah battery at least 24 hours).
When the motorhome is not used for a long time, consumers with a perma-
nent supply should be disconnected from the battery.
" 12V supply on the IT ... / LT control and switch panel must be switched
off.
" Fully charge the living area battery before closing down the system.
" Remove the MNL connector on block 4 of the electroblock.
The living area battery now only supplies the permanent positive input of the
radio (e.g. to prevent the code from having to be re-entered every time after
closing down).
Follow the instructions of the battery manufacturer.

4.2 Additional functions
This output can be used to continually supply an existing refrigerator control-
ler.
The power supply to this consumer is automatically interrupted as soon as
the engine starts running (the D+ connection is live in this case or switched
to ground, depending on the type of vehicle). The awning light can still be
used even if the 12V power supply is switched off.
The conventional D+ signal (D+ connection is live when the engine is run-
ning) is evaluated directly.
An integrated D+ converter enables the connection of vehicles for which the
D+ signal is provided as an active ground signal (e.g. FIAT).
A changeover switch on the electroblock specifies which D+ signal is to be
evaluated.
This feature provides an automatic max. 2 A float charge for the starter bat-
tery when the 230V mains is connected to the electroblock.
This output is suitable for supplying the side marker lights of the motorhome.
The associated voltage output is switched on as soon as control signal ”Ve-
hicle lighting ON” of the basic vehicle is applied at the relevant control input
of the EBL 271.
This output provides a supply voltage to operate an electric fold-away bed.
The voltage is only applied when switch AUX ON of the control and switch
panel is ON AND D+ is not applied, i.e. the vehicle engine is not running.
This prevents unintentional operation of the bed whilst the vehicle is moving.
5Maintenance
The EBL 271 electroblock is maintenance free.
Clean the electroblock with a soft, slightly damp cloth and mild detergent.
Never use spirit, thinners or similar substances. Do not allow liquids to enter
the electroblock.
