Y If the device becomes too hot due to excessive ambient temperature or
lack of ventilation, the charging current is automatically reduced. Nevert-
heless, always prevent the device from overheating.
Y If the automatic shutdown mechanism of the battery monitor is triggered,
fully charge the living area battery.
3.4 Closing down the System
Y ATTENTION!
Total discharge.
Damage to the living area battery:
F Fully charge the living area battery before and after closing down the
system. (Connect a vehicle with an 80 Ah battery and a vehicle with a
160 Ah battery to the mains for at least 12 and 24 hours respectively).
Y ATTENTION!
Permitted input voltages exceeded.
Damage to connected consumers:
F Do not operate any connected Schaudt solar charge regulator without
battery.
F If the battery is going to be changed or removed, first remove ”+ solar
cell” connector on the solar charge regulator.
³Fully charge the living area battery before closing down the system.
The living area battery is then protected against total discharge. This only
applies if the battery is intact. Follow the instructions of the battery manufac-
turer. The shut down system requires approx. 4 Ah per month.
Disconnect the living area battery from the 12 V power supply if you are not
going to use the motorhome for a longer period (during the winter for exam-
ple). For this, the system has a battery cut-off mechanism that isolates the
living area battery from the vehicle. The battery cut-off is enabled on the
DT/LT ... control and switch panel (see operating manual of DT/LT ... control
and switch panel).
³Switch off the main switch on the DT/LT ... control and switch panel.
³Enable the battery cut-off on the DT/LT ... control and switch panel (see
operating manual of DT/LT ... control and switch panel).
Y The living area battery can also be charged using the internal charger
module, an auxiliary battery charging unit, the solar charge regulator and
the alternator when the battery cut-off switch is switched off.
³Fully charge the living area battery before closing down the system.
³Remove the ”+ solar cell” connector on the solar charge regulator.
³Remove the clamps from the battery poles.
Y The battery alarm is no longer active.
Y The frost protection valve opens for certain heater systems when the li-
ving area battery is isolated from the Electroblock via the battery cut-off.
The boiler and water tank empty when the frost protection valve is open.
For more information, see the instruction manual of the heater system.

4 Application and Functions in Detail
Y This device is intended solely for installation in a vehicle.
The EBL 226 C +OVP Electroblock is the central energy supply device for all
12 V consumers in the electrical system on board the motorhome/caravan. It
is normally located inside a cupboard or storage area and is accessible from
the front for fuse changes.
The electronic block is suitable for applications in which the risk of overvol-
tage is especially high. For example, lightning strikes in the public mains net-
work, generator operation, poor electronic installations or trips to foreign
countries.
For this, overvoltage protection is fitted in the electronic block between the
mains connection and the charge module.

230 V AC ±10 %, 47 to 63 Hz sinusoidal, protection class I
12 V outputs may be loaded with max. 90% of the rated current of the re-
spective fuse (see also assembly instructions or front panel).
4.1 Battery functions
6-cell lead acid or lead gel 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
the battery cut-off (enabled on the DT/LT ... control and switch panel) isola-
tes the following connections from the living area battery:
F all 12 V consumers
F the frost protection valve
This prevents slow discharge of the living area battery by the standby cur-
rent during shutdown of the vehicle (discharge with approx. 4 Ah in month).
The batteries can still be charged using the Electrobloc, the alternator, an
auxiliary charging unit or the solar charge regulator, even when the battery
cut-off switch is switched off.
The switching option provided by the battery selector switch ensures opti-
mum charging of the two battery types, lead gel and lead acid.
The battery monitor of the DT/LT ... control and switch panel constantly mo-
nitors the living area battery with dynamic voltage threshold. Lower di-
scharge currents cut off ”earlier” than with larger currents. This provides im-
proved total discharge protection. Monitoring is also performed in the
switched-off state. A warning message is displayed below 12.0 V (,depen-
ding on current drain).
If the voltage of the living area battery sinks further, falling below 10.5 V, the
battery monitor immediately switches off all 12 V consumers. The control
and switch panel also switches itself off. Only the frost protection valve con-
tinues to be powered (so it stays closed). Before switch-off, all switch states
are the value of the battery capacity are stored and restored after power-on.

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 12 V supply can begin operation for a short time. To do this,
switch on the 12 V main switch on the DT/LT ... control and switch panel.
However, if the battery voltage remains below 11.0 V, the 12 V power supply
can not be turned back on.
Fully charge the living area battery as soon as possible. For further informa-
tion, see ”Battery voltages” in the instruction manual of the relevant DT/LT ...
control and switch panel .
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/compressor refrigerator is powered by the living area battery
when the vehicle engine is not running.
The step output is protected by a self-resetting 15A fuse.
If a fault occurs, such as overcurrent, the self-resetting fuse interrupts the
relevant circuit.
After rectification of the fault, the fuse automatically resets after approx. 1
minute.
Maximum permitted charge current 14 A, protected with 15 A
Depending on the solar charge regulator used, either only the living area
battery is charged or the living area battery and the starter battery.
The power supply to the awning light is automatically interrupted as soon as
the engine is started and the D+ connection is live. The awning light can still
be used even if the 12 V power supply is switched off.
The tank heater is enabled via the DT/LT ... control and switch panel. The
tank heater can still be used even if the 12 V power supply is switched off.
The side marking lights are switch on via the integrated relay. They are po-
wered from the start battery. The relay is activated via terminal 58.
5Maintenance
The Electrobloc requires no maintenance.
Clean the electronic block with a soft, slightly damp cloth and mild detergent.
Never use spirit, thinners or similar substances. Do not allow liquids to enter
the electronic block.
