The CSV 409 A caravan charging system is the central power supply unit for
all 12 V consumers connected to the caravan’s electrical system. It is nor-
mally fitted inside a cabinet or a stowage space and can be accessed from
the front to change a fuse.
The caravan charging system has been designed solely for connecting up to
a 12 V onboard supply.
Connected units can be supplied from the caravan battery or the towing
vehicle’s battery if a mains supply is not available.
Since the device provides a hum-free, stabilised output voltage, it is also
possible to connect and supply power to sensitive consumers (e.g. transistor
lamps or radios).
The CSV 409 A caravan charging system consists of:
FA charging module for recharging all of the connected batteries
FThe complete 12 V distribution system
FThe fuses for the 12 V power circuits
FA battery booster
At least one switch panel ST ... has to be connected for operation.
Connection options are available for:
FSolar charger
F12 V indicator
FMains indicator
F12 V supply to a control and display panel
Flat vehicle fuses are used to protect the various circuits.
FOvertemperature
FOverload
FShort circuit
230 V AC voltage 10 %, 47 -- 63 Hz sinewave, protection class I
12 V outputs shall only be loaded up to a maximum of 90 % of the rated
current of the associated fuse (see block diagram or nameplate).
All of the consumers must not exceed the following loads when combined:

3.1 Battery functions
6-cell lead-acid or lead-gel batteries from 80 Ah upwards
Charging the caravan battery whilst driving; increasing the supply voltage
coming from the towing vehicle via the battery booster
The 12V main switch (rocker switch with neutral position on the control and
switch panel) disconnects all 12V consumers from the caravan battery
(except: the control electronics of a refrigerator).
This prevents the caravan battery from being slowly discharged by closed-
circuit current.
The batteries can still be charged using the caravan charging system, the
towing vehicle or the solar charger, even when the main battery-switch is
switched off.
The switching option provided by the battery selector switch ensures opti-
mum charging of the two different types of battery, lead-acid and lead-gel.
The consumers are switched off (except for the refrigerator) when the
caravan is hitched to the towing vehicle and the ignition is switched on
(power at terminal 10 and trailer hitch TH). The consumers can be switched
back on at any time. (The automatic disconnector does not prevent swit-
ching back on).
No closed circuit current when the ignition of the towing vehicle is switched
off; additional current consumption by the fridge’s control electronics (see
documentation supplied by the fridge manufacturer);
measured when all of the consumers inside the caravan are switched off

3.2 Additional functions
This output supplies the control electronics in a fridge:
FFrom the caravan battery
FFrom the towing vehicle’s battery when the ignition is switched on
FFrom the mains supply when it is connected up
Y12V operation of the refrigerator only works if the caravan is connected to
a towing vehicle with the engine running.

5 Operation
Operation of the caravan power supply occurs exclusively via the connected
control and switch panel.
The CSV 409 A caravan charging system does not require daily operation.
Settings only have to be carried out once if the battery type is changed
(lead-acid or lead-gel), during initial start-up or when retrofitting accessories
(see chapter 5.3 and the CSV 409 A installation instructions).
5.1 Switching on and off
5.1.1 Control and switch panels of type LT ...
The control and switch panels of type LT ... are supplied with individual ope-
rating instructions included with the vehicle. Please refer to these instruc-
tions for operating information.
5.1.2 Switch panel ST 05
Fig. 3 Switch panel ST 05
In the simplest case, the switch panel ST 05 is connected to the caravan
power supply. It simply has a rocker switch with neutral position.
The 12 V supply to the living area is switched on via the switch. Exception:
FCompressor/AES refrigerator control
YWhen starting these consumers for the first time after switching off the
CSV 409 A caravan power supply, replacing the battery or reconnecting
the leisure battery after a longer period, the 12 V main switch on the
switch panel must be switched on briefly.
Press the left-hand button briefly.
The 12 V power supply to the living area is switched on.
Press the right-hand button briefly.
The 12 V power supply to the living area is switched off.

5.2 Starting the system
YATTENTION!
Caravan charging system can be set up incorrectly!
The connected devices will be damaged. Therefore prior to starting:
FYou must ensure that the battery selector switch (Fig. 2, Pos. 21) is
set to the correct position for the type of battery being used.
Press the rocker switch so that it is briefly in the “ON” position.
The 12 V main switch switches all consumers on and off (exception: a
fridge’s control electronics).
YATTENTION!
Violation of 230 V mains voltage limit!
Will damage the caravan charging system, 12 V consumers or other con-
nected devices:
FThe generator must not be switched in until it is running smoothly.
FIt is essential that the generator complies with the mains supply speci-
fications.
FDo not connect the caravan charging system to the onboard mains
voltage on car ferries (a non-problematic mains voltage cannot always
be guaranteed on car ferries).
Utilisation of an upstream overvoltage protection device (OVP) is
recommended.
YATTENTION!
Battery buffer function missing!
The connected devices will be damaged:
FNever run the solar charger without a battery being connected.
YATTENTION!
Battery discharge!
Towing vehicle cannot be started:
FSwitch off the ignition when the towing vehicle is at a standstill.

5.3 Changing the battery
YATTENTION!
Wrong battery type or incorrectly connected battery!
Will damage the battery or the devices connected up to the caravan
charging system:
FBatteries shall only be changed by qualified personnel.
FFollow the instructions of the battery manufacturer.
FThe caravan charging system is to be used solely for connecting the
12 V power supply to 6-cell lead-gel or lead-acid batteries. Never use
unapproved types of battery (e.g. NiMH batteries).
YOnly batteries of the same type and capacity should normally be used,
i.e. same as those installed by the manufacturer.
YYou can change over from lead-acid to lead-gel batteries. You cannot
change over from lead-gel to lead-acid batteries! Your vehicle manufactu-
rer will provide you with information about this.
Disconnect the battery from the caravan charging system by switching
the 12 V main switch off.
Unhitch the caravan from the towing vehicle.
Replace the battery.
Check once more to ensure that you have fitted the correct type of bat-
tery afterwards.
YDANGER!
Battery selector switch set incorrectly!
Danger of explosion caused by the build up of oxyhydrogen gas.
FSet the battery selector switch to the correct position.
YATTENTION!
Battery selector switch set incorrectly!
The battery will be damaged.
FSet the battery selector switch to the correct position.
Disconnect the caravan charging system from the mains before resetting
the battery selector switch.
Move the battery selector switch (Fig. 2, Pos. 21) into the relevant posi-
tion using a thin object (e. g. ball-point pen):
FLead-gel battery: Set the battery selector switch to “Lead-gel” (Gel).
FLead-acid battery: Set the battery selector switch to “Lead-acid”
(Säure).
Start the system as instructed in Chapter 5.2.

5.4 Operating faults
The majority of power supply system faults are caused by blown fuses.
Please contact our customer service address if you cannot eliminate the
fault using the following table.
If this is not possible, e.g. if you are abroad, you can have the caravan char-
ging system repaired at a specialist workshop. In this case you must ensure
that the warranty is not invalidated by incorrect repairs being carried out and
Schaudt GmbH will not accept any liability for damage resulting from such
repairs.

tery is going to be changed or removed.
Press the rocker switch (12 V main switch) so that it is briefly in the
“OFF” position.
The caravan battery must be fully charged before closing the system
down.
The caravan battery is then protected against total discharge. This applies
only if the battery is intact. Follow the instructions of the battery manufactu-
rer.
The caravan battery must be fully charged before closing the system
down.
