2Introduction
Y This device is intended solely for use in vehicles.
This instruction manual contains important information for safe operation of
the device. Ensure you read and follow the safety instructions provided.
The instruction manual should be kept in the vehicle at all times. Ensure that
other users are made aware of the safety regulations.
Y This device is not intended to be used by persons (including children)
with limited physical, sensory or mental aptitude or lack of experience
and/or knowledge unless they are supervised by a person responsible for
their safety or have received instruction from this person as to how the
device is used.
Children are to be supervised so as to ensure they do not play with the
device.
3Operation
The electrobloc is operated solely via the IT ... / LT ... control and switch panel connected. .
Overvoltage protection
OVP
3.1 Starting up the system
No operation of the EBL 99 K or EBL 99K with OVP electrobloc is required
for daily use (exception: the battery cut-off switch should be disabled when
the vehicle is not in use, see Section 3.4).
One-off settings only have to be configured 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 assembly instructions).
The EBL 99 K with OVP electrobloc is suitable for all applications in which
the danger of overvoltage is especially large. For example, lightning strikes
to the national grid, generator operation, poor electronic installations or trips
to distance countries.
For this, an overvoltage protection unit is fitted in the electrobloc between
the mains connection and the charge module.
Y AT T E NTION!
Incorrect electrobloc settings.
Damage to connected devices. Therefore prior to starting:
F Ensure the leisure area battery is connected.
F Ensure that the battery selector switch (Fig. 3, Pos. 10) is set to the
correct position for the battery installed.
811.419 BA / EN
Turn the battery cut-off switch (see Fig. 3, Pos. 12) to ”On”.
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.

Outputs are exceptions:
F Floor light/step
F Heater
F Frost protection valve
These outputs are not disabled via the main switch of the IT .. . /LT control
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
Y AT T E NTION!
Use of incorrect battery types or incorrectly rated batteries.
Damage to the battery or devices connected to the electrobloc:
F Batteries should only be changed by qualified personnel.
F Follow the battery manufacturer’s instructions.
F Only connect the electrobloc to 12V power supplies with rechargeable
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. 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.
F AES/compressor refrigerator
F Spare 4
Changing the battery
Electrically isolate the battery from the electrobloc by disabling the bat-
tery cut-off switch on the electrobloc (also see Section 3.4).
Replace battery.
After changing the battery, recheck which type of battery has been inser-
ted.
Y DANGER!
Incorrect setting of the battery selector switch.
Risk of explosion due to build up of explosive gases:
F Set the battery selector switch to the correct position.
Disconnect the electrobloc from the mains before adjusting the battery
selector switch.

Starting up
the system
3.3 System faults
Set the battery selector switch (Fig. 1, Pos. 1) to the correct position
using a thin object (e.g. a ballpoint pen):
F Lead gel battery: Set the battery selector switch to ”Lead-gel”.
F Lead acid battery: Set the battery selector switch to ”Lead-acid”.
Start up the system as described in Section 3.1.
Flat vehicle fuses
Discharged battery --
start motor
In most cases of a fault in the energy supply system, a flat battery or a faulty
fuse is the cause.
If the battery is discharged, consumers can always be supplied by starting
the motor of the base vehicle.
Please contact our customer service department if you can not rectify the
fault using the following table.
If this is not possible, e.g. if you are abroad, you can have the electrobloc
repaired at a specialist workshop. Please note that the warranty becomes
void if incorrect repair work is carried out. Schaudt GmbH can not accept
liability for any damages resulting from such repairs.

Y AT T E NTION!
Total discharge.
Damage to the living area battery:
F Fully charge the living area battery before and after closing down the
system. (Connect vehicle tothemainswithan80Ahbatteryatleast
12 hours and with a 160Ah battery at least 24 hours).
Disconnect the living area battery from the 12V power supply if the motorhome 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 from the main switch of the IT ... /LT... control and switch pa-
nel.
Turn the battery cut-off switch (see Fig. 3, Pos. 12) to ”Off”. The following
connections are isolated from the living area battery:
F All 12V consumers
F Frost protection valve
F Control and switch 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.
Y If the living area battery is isolated from the electrobloc with the battery
cut-off, the frost protection valve of the combination heating opens. A
loss of water is possible (see operating instructions of the combination
heating).

Battery charging via
Mains connector
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 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.
With the switching option with the battery selector switch, the optimal charging of the two types of batteries, lead-gel and lead -acid, is guaranteed (approx. 5 -- 20mA)
With control and switch panel: approx. 5 -- 20mA
(depending on the control and switch panel used) under the following conditions:
F No mains connection
F Living area battery voltage 12.6V
F 12V main switch ”OFF”

Characteristic charging curve IUoU
End of charge voltage 14.3V
Charging current 18A
Voltage for float charge 13.8V with automatic switch function
Automatic disconnector
Starter battery
Charging current float charge max. 2A
The battery monitor compares the current of the living area battery to 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 (shorter than 2 seconds), caused by high current when switching on consumers.
If an overload or an insufficiently charged living area battery causes the voltage to fall so low that the automatic disconnector is triggered, any non-essential 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 possible. For more information, see the description of ”battery voltages”.
