2. Safety Information
*The electrical installation of the motorhome has to be in accordance with current DIN-, VDE- and
ISO-regulations. Alterations will endanger the safety of persons and the vehicle.
Due to the above mentioned regulations and safety rules, alterations are therefore prohibited.
*The connection of the EBL to the mains supply has to be in accordance to national installation rules.
*The energy system EBL 208 S must not be modified.
*The connection of the energy system has to be done by qualified personnel only and must be
conform to specifications mentioned in this operating instruction manual:
see instruction manual section 4.2 'Installation'
section 5 'Electrical Installation'
and in enclosure schematic diagram of EBL 208 S
*In the following text special notice should be paid to the signs shown below:
CAUTION !
Electrical current hazard warning.
CAUTION !
General hazard warning.
3. Operating Instructions
3.1 Controls
12V fuses Pluggable FK2 automotive fuses
battery-type selector switch The mains plug of the energy system has to be taken off prior to
actuating the battery-type selector switch on the frontside of the device.
Eg Seperate vehicle from mains supply.
Before power-up of the energy system this switch has to be selected
according to the type of battery used (lead-acid or lead-gel).
The switch ensures an optimum charge of the connected battery type.
To actuate use a thin tool (eg a pencil tip).
Caution !
An incorrect selected battery-type switch may damage the batteries and there may be an
explosion-hazard caused by detonating gas.
battery cut-off switch The battery cut-off switch 'Battery' seperates the control and switch board
and the anti-freeze valve of the heater system from the living-area battery,
to inhibit stand-by currents while vehicle is non-operative.
See detail 6.2 'Shut-Down'
Attention !
Please note if anti-freeze valve is deactivated by the battery cut-off switch 'Battery', in
position 'off', the safety-valve of the boiler opens automatically.
note: To reactivate all load after being cut-off by battery cut-off switch 'Battery' or after a battery
change, please actuate 12V main switch on the instrument panel.
12V main switch With push-button switch '12V EIN/AUS' all load, except automatic step
on instrument panel and AES-refrigerator, is being switched on and off.
Please refer to instruction manual of the instrument panel.

3.2 Relay Functions
battery cut-off relay This relay seperates the starter and living-area battery when the engine is
not running and if there is no voltage on terminal 'D+'.
Both batteries are connected in parallel and therefore simultaneously char-
ged while engine is running.
main-switch relay This relay is controlled by the push-button switch on the instrument panel
bistable '12V EIN/AUS'. It switches off all 12V load, except the automatic step and
the AES-refrigerator.
awning-light relay The awning-light is operational only with turned on main-switch and if the
engine is not running with no voltage on terminal 'D+'.
refrigerator cut-off relay This relay controls the power supply of the refrigerator.
The refrigerator gets its power from the starter battery only if the engine is
running and if there is a voltage on terminal 'D+'.
An AES refrigerator is provided from the living-area battery when the
engine is not running.
charging relay battery 1 This relay automatically provides a 2A trickle-charge to
(starter battery) the starter battery if mains supply is on.
3.3 Battery Monitor Module
The battery monitor compares the voltage of the living-area battery with a reference voltage.
As soon as the battery voltage is lower than 10.5V all 12V load will be switched off.
Only the automatic step and a AES-refrigerator are still provided with power. Short falls (< 2 sec )
below the threshold voltage, due to high inrush currents of connected load do not affect the
automatic cut-off function.
If the automatic shut-down has been triggered due to overload or an insufficiently charged battery
all non-essential load should be switched off.
By actuating the '12V on/off' push-button switch on the instrument panel it may be possible to
reactivate the 12V system for a short period of time.
However, the 12V System can not be switched on if the battery voltage stays under 11.0V.
In any case the living-area battery should be fully recharged as soon as possible.
4. Transport, Storage, Installation

*The energy system EBL 208 S is maintenance-free.
*For cleaning use a soft moisturized cloth with a mild detergent. Do not use methylated spirit,
paint thinner, etc. Liquids must not be allowed to get into the cabinet.
7. Malfunctions
*If due to high surrounding temperature or bad ventilation the EBL gets too hot, the charging current will
be decreased automatically. However, overheating should in any case be prevented.
*Should repairs be necessary, please contact the service department of Schaudt GmbH,
ph. 0049-(0)7544-9577-16, eMail: [email protected]
*If it is not possible to see the manufacturer for service (eg being overseas), necessary repairs can be
carried out by a qualified workshop.
*Unqualified repairs enforce expiration of warranty. The manufacturer Schaudt GmbH disclaims it's
liability and is therefore not liable to resulting damages.
