2 Introduction
This instruction manual contains important information on safe operation of
the device. Make sure you read and follow the safety instructions provided.
The operating instructions should always be kept in the vehicle. All safety in-
formation must be passed on to other users.
3 Operation
The electroblock is operated solely via the IT ... / LT ... control and switch
panel connected. .
For daily use, no operation is needed on the EBL 30 electroblock (excep-
tion: the battery cut-off switch should be disabled when the vehicle is not in
use, see Section 3.4).
One-off adjustments only have to be made if the battery type is changed
(lead-gel or AGM), during initial start-up or when retrofitting accessories (see
Section 3.2 and the installation instructions for the EBL 30).
The EBL 30 with OVP electroblock is suitable for all applications in which the
risk of overvoltage is particularly high. For example, lightning strikes on the
national grid, generator operation and poor electronic installations at cam-
ping sites.
For this, an overvoltage protection unit is fitted in the electroblock between
the mains connection and the charge module. In the event of over or under-
voltage, this overvoltage protector isolates the electroblock from the 230V
supply within just a few milliseconds. It remains cut off until the main voltage
has normal values again.
3.1 Starting up the system
YATTENTION!
Incorrect electroblock settings.
Damage to connected devices. Therefore prior to starting:
FEnsure the leisure area battery is connected.
FEnsure that the battery selector switch (Fig. 4, Pos. 10) is set to the
correct position for the battery installed.
"Move the battery cut-off switch (see Fig. 4, Pos. 12) to the ”Battery ON”
position.
"Use the main 12V switch (see instruction manual of relevant control and
switch panel) to switch on/off all the consumers and the control and
switch panel.
The following outputs are exceptions:
FFloor light/step
FHeater
FFrost protection valve
FAES/compressor refrigerator
FFloor light 4A
FFloor light 4B
These outputs are not disabled from the main switch of the IT ... / LT ... con-
trol and display panel.
Please refer to the operating instructions of the IT ... / LT ... control and
switch panel for further information. .

3.2 Changing the battery
YATTENTION!
Use of incorrect battery types or incorrectly rated batteries.
Damage to the battery or devices connected to the electroblock:
FBatteries may only be changed by qualified personnel.
FFollow the battery manufacturer’s instructions.
FOnly use the electroblock to connect to 12V power supplies with re-
chargeable 6-cell lead-gel or AGM batteries. Do not use any unsuita-
ble battery types.
YNormally only batteries of the same type and capacity should be used,
i.e. the same as those installed by the manufacturer.
"Electrically isolate the battery from the electroblock. For this, switch off
the battery separation switch on the EBL 30 electroblock (refer also to
Section 3.4).
"Replace the battery.
"After changing the battery, recheck which type of battery has been inser-
ted.
YDANGER!
Incorrect setting of the battery selector switch.
Risk of explosion due to build up of explosive gases:
FMove the battery selector switch to the correct position.
"Disconnect the electroblock from the mains before adjusting the battery
selector switch.

"Move the battery selector switch (Fig. 1, Pos. 1) to the correct position
using a thin object (e.g. a ballpoint pen):
FLead-gel battery: Move the battery selector switch to ”Gel”.
FAGM battery: Move the battery selector switch to ”AGM”.
"Start up the system as described in Section 3.1.

3.3 Faults
A flat battery or defective fuse is the cause of most faults in the power sup-
ply system.
If the battery is discharged, consumers can always be powered by starting
the engine of the base vehicle.
Please contact our customer service address 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
warranty is not invalidated by incorrect repairs being carried out. Schaudt
GmbH will not accept any liability for damage resulting from such repairs.

YThe 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.
YIf the automatic shutdown mechanism of the battery monitor is triggered,
fully charge the living area battery.
3.4 Closing down the system
The battery is isolated by switching off the battery cut-off switch.
YATTENTION!
Total discharge.
Damage to the leisure area battery:
FFully 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).
Disconnect the living area battery from the 12V power supply if the motor-
home is not used for a longer period (during the winter for example).
"Fully charge the living area battery before closing down the system.
"Switch off the main switch on the IT ... / LT ... control and display panel.
"Move the battery cut-off switch (see Fig. 4, Pos. 12) to the ”Battery OFF”
position. The following connections are isolated from the living area bat-
tery:
FAll 12V consumers
FFrost protection valve
FOperator and control panel
The living area battery is then protected against total discharge. This only
applies if the battery is intact. Follow the battery manufacturer’s instructions.
YIf the living area battery is isolated from the electroblock with the battery
cut-off, the frost protection valve of the combination heater opens. A loss
of water is possible (see the operating instructions for the combination
heater).

4 Application and functions in detail
The EBL 30 electroblock is the central power supply unit for all 12V consu-
mers in the vehicle’s electrical system. It is usually located in a cupboard or
storage area and is accessible from the front in order to change fuses.

Fcontrol and monitoring functions
An IT ... or LT ... control and switch panel must be connected for operation.
These devices control the electrical functions in the vehicle’s living area, inc-
luding accessories.
There is also an option to connect an additional charger and a solar loading
regulator.
Flat vehicle fuses protect the various circuits. The D+ output is an exception.

4.1 Battery functions
6-cell lead-gel or AGM batteries, 55 Ah and above
Simultaneous charging of the starter battery and the living area battery via
the alternator, parallel connection of the batteries via a cut-off relay
Maximum permitted charge current 14 A, fused with 15 A (for leisure area
battery), simultaneous charging of the starter battery
The battery is isolated with the battery cut-off switch.
This prevents the living area battery from slowly discharging due to closed
circuit current while the vehicle is not in use.
The switching option provided by the battery selector switch ensures opti-
mum charging of the battery types, lead-gel and AGM, for mains supply.
The battery monitor compares the current of the living area battery with a
reference current. As soon as the battery current drops below 10.5V, all 12V
consumers are switched off via main switch relays 1 and 2.
Only the frost protection valve continues to be powered.
The automatic disconnector is not triggered by short-term low voltage (shor-
ter than 2 seconds), caused by high current when switching on consumers.
If an overload or an insufficiently charged living area battery causes the vol-
tage to fall so low that the automatic disconnector is triggered, any non-es-
sential consumers should be switched off.
If need be, the 12V supply can begin operation for a short time. For this,
switch on the 12V main switch on the control and switch panel.
However, if the battery current remains below 11.0V, the 12V supply can not
be switched on again. Fully charge the living area battery as soon as possi-
ble. For more information, see the description of ”battery voltages”.

4.2 Additional functions
This relay supplies the AES/compressor refrigerator with power from the
starter battery when the vehicle engine is running and the D+ connection is
live. An AES refrigerator is powered by the living area battery when the vehi-
cle engine is not running.
This feature provides an automatic max. 6 A float charge for the starter bat-
tery when the 230V mains is connected to the electroblock.
The electroblock is isolated from the mains within 10ms in the event of a
voltage greater than 265 V eff. The electroblock switches itself back on
again by itself after the mains voltage has attained the normal value.
