The CSV 410 caravan charging system is the central power supply unit for
all 12 V consumers connected to the caravan’s electrical system. It is usually
located in a cupboard or storage area and is accessible from the front in or-
der to change fuses.
The caravan charging system has been designed solely for connecting to a
12 V onboard supply.
Connected units can be supplied from the caravan battery or the towing ve-
hicle’s battery if a mains supply is not available.
Because the device provides a hum-free, stabilised output voltage, sensitive
consumers such as transistor lights and radios can be connected and powe-
red.
The CSV 410 caravan charging system consists of:
Fa charge module for charging all connected batteries
Fthe complete 12V distribution system
Ffuses for the 12V circuits
Fa battery booster
An ST ... switch panel must be installed as a minimum to run the system.
Connections are provided for:
FSolar charge regulator
FControl and display panel
Flat vehicle fuses protect the various circuits.

3.1 Battery functions
6-cell lead acid or lead gel batteries, 80 Ah and above
Charging the caravan battery whilst driving; increasing the supply voltage
coming from the towing vehicle via the battery booster
The 12 V main switch (rocker switch with centre position on the control and
switch panel) disconnects all the 12 V consumers from the caravan battery
(exception: the fridge controller electronics).
This prevents the caravan battery from being slowly discharged by standby
currents.
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
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 consumers are switched off (except for the refrigerator) when the cara-
van is hitched to the towing vehicle and the ignition is switched on (power on
terminal 10 and trailer hitch TH). Consumers can be switched on again at
any time (the automatic disconnector does not prevent this).
No standby current when towing vehicle ignition is off; additional current con-
sumption by the fridge’s control electronics (see documentation supplied by
the fridge manufacturer);
Measured when all the consumers inside the caravan are switched off.

5 Operation
The caravan charging system is operated solely from the control and switch
panel connected.
The CSV 410 caravan charging system does not require daily operation.
Initial setting is only needed after the type of battery (lead-acid or lead-gel)
has been changed or during commissioning or when upgrading with acces-
sories (see Section 5.3 and CSV 410 installation instructions).
5.1 Switching on and off
5.1.1 Control and switch panels of type LT ...
Control and switch panels of type LT ... are supplied with a separate opera-
ting manual (kept with the vehicle). Please refer to this manual for instruc-
tions on operation.
5.1.2 Switch panel ST02 or ST05HS+PU
ST05 ST02HS+PU (option)
Fig. 3 Switch panels ST05 and ST02HS+PU
In the simplest case, an ST05 switch panel is connected to the caravan
charging system. It only has one rocker switch with a centre position. The
optional ST02HS+PU also has a pump switch.
The 12V supply of the living area is switched on using the button. Excep-
tions:
FCompressor/AES-refrigerator-control unit
These consumers are still operable even when the 12V power supply is swit-
ched off.
Press rocker switch (12V main switch) so that it is briefly in the ”I” po-
sition (ON).
F
The 12V supply to the living area is now switched on.
Press 12V main switch so that it is briefly in the ”O” position (OFF).
The 12V supply to the living area is now switched off.

5.1.3 Connect pump (option)
For the pump to be switched on, the 12V supply voltage must first be swit-
ched on (see Section 5.1.2 for the main supply).
Move the switch with the pump symbol upwards.
The supply voltage for the water pump is enabled:
FThe pump may switch on briefly (e.g. in a pressure system).
FIn other systems, the pump is enabled by the water tap contacts.
Move the switch with the pump symbol downwards.
5.2 Starting up the system
YCAUTION!
Incorrect settings on the caravan charging system.
Damage to connected devices. Therefore prior to starting:
FEnsure that the battery selector switch (Fig. 2, Pos. 21) is set to the
correct position for the battery installed.
Press rocker switch (12V main switch) so that it is briefly in the ”I” po-
sition (ON).
The 12 V main switch switches all consumers on and off (exception: the
fridge controller electronics).
YCAUTION!
Exceeding the thresholds of the 230V mains supply.
Will damage the caravan charging system, 12 V consumers or other con-
nected devices:
FDo not connect a generator until it is running smoothly.
FIt is essential that the generator conforms to the specifications of the
mains supply.
FDo not connect the caravan charging system to the onboard mains
voltage on car ferries (non-problematic mains voltage cannot always
be guaranteed on car ferries).
The use of an upstream overvoltage protection device is recommen-
ded.
YCAUTION!
No battery buffer function
Damage to connected devices:
FDo not operate solar regulator without battery connected.

YCAUTION!
Battery discharge
Towing vehicle can no longer start:
FSwitch off the ignition when the towing vehicle is stationary.
5.3 Changing the battery
YCAUTION!
Use of incorrect battery types or incorrectly rated batteries.
Will damage the battery or the devices connected up to the caravan char-
ging system:
FBatteries should only be changed by qualified personnel.
FFollow the battery manufacturer’s instructions.
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
non-approved battery types such as NiMH batteries.
YNormally only batteries of the same type and capacity should be used,
i.e. the same as those installed by the manufacturer.
YIt is possible to swap lead acid batteries with lead gel batteries. You can-
not change over from lead-gel to lead-acid batteries. Contact the vehicle
manufacturer for more information.
Disconnect the battery from the caravan charging system by switching
the 12 V main switch off.
Unhitch the caravan from the towing vehicle.
Replace 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.
YCAUTION!
Incorrect setting of the battery selector switch.
Damage to the battery.
FMove 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) to the correct position
using a thin object (e.g. a ballpoint pen):
FLead gel battery: Set the battery selector switch to ”Lead-gel”.
FLead acid battery: Set the battery selector switch to ”Lead-acid”.
Start up the system as described in Section 5.2.

5.4 Faults
A fault in the power supply system is usually caused by a blown fuse.
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 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.
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.
5.5 Shutting down the system
Press the rocker switch (12 V main switch) so that it is briefly in the
”OFF” position.
5.6 Closing down the system
YCAUTION!

Damages the caravan battery:
FFully charge the caravan 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 24 and 36 hours respectively.
YCAUTION!
Permitted input voltages exceeded.
Damage to connected consumers:
FDo not operate any connected Schaudt solar charge regulator without
battery.
FWhen the battery is changed or removed, first unplug the ”+ solar cell”
connector on the solar charge regulator.
Fully charge the caravan battery before closing down the system.
The caravan battery is then protected against total discharge. This only ap-
plies if the battery is intact. Follow the battery manufacturer’s instructions.
Fully charge the caravan battery before closing down the system.
Remove the clamps from the battery terminals.
Remove the ”+ solar cell” connector on the solar charge regulator.
