2 Introduction
This instruction manual contains important information on safe operation of
the device. Make sure you read and follow the safety instructions provided.
The instruction manual should always be kept in the vehicle. All safety infor-
mation must be passed on to other users.
3 Operation
A 12V main switch and a pump switch are available as a control on a shared
switch panel (ST02HS+PU).
3.1 Connect the 12V supply voltage
YATTENTION!
Battery discharge when towing vehicle is hitched
Towing vehicle cannot be started:
FSwitch off the ignition when the towing vehicle engine is not running
(depending on model).
FDisconnect the connector on the towing vehicle (depending on mo-
del).

"Press rocker switch (12V main switch) so that it is briefly in the ”I” po-
sition or touch the sensor (LT151).
FThe power supply is connected to all the consumers.
FSupply is provided via the battery of the towing vehicle when connec-
ted up. Circuit 5 (awning light) is disabled so that it cannot be swit-
ched on whilst the vehicle is moving (a legal regulation in some coun-
tries). For mains or battery operation, power is supplied from the
caravan battery (also circuit 5).
"Refer to the documentation of the vehicle manufacturer for more details
about and operation of the 230V power cut-out.
"Press 12V main switch so that it is briefly in the ”O” position or touch
the sensor (LT151).
3.2 Connect the pump
For the pump to be switched on, the 12V supply voltage must first be swit-
ched on (see Section 3.1 for the main supply).
"Move the switch with the pump symbol upwards or touch the sensor
(LT151).
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 or touch the sen-
sor (LT151)..
3.3 Faults
A fault in the power supply system is usually caused by a blown fuse.
Please contact our customer service team 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 distri-
butor 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.

YThis device is intended for permanent installation in a caravan.
The CV 304 caravan distributor is the central power distribution unit for all
consumers (12V and 230V) in the caravan’s electrical system. It is usually
located inside a cupboard or storage area, and is accessible from the front in
order to change fuses and to access the main switch.
The caravan distributor is only designed for connection to the 12 V power
supply.
Connected devices can be supplied via a battery installed in the caravan or
via the towing vehicle’s battery. Switchover is automatic on connecting the
plug to the towing vehicle (requirement: 13-pole connector, connected in ac-
cordance with EN 1648-1 -- voltage at pin 10 with ignition switched on).

The CV 304 caravan distributor contains:
Fthe complete 12V distribution unit
Fthe fuses for the 12V circuits
Fthe 230V distribution unit
FSpace for an optional dual power cut-out is provided (for 230V distribu-
tion).
The device does not have its own power supply or charger.
Connections are provided for:
FThree circuits each with 10 A max.
FOne circuit (max. 5 A) for a water pump. This circuit is enabled/disabled
with the pump switch.
FAnother circuit (max. 5 A) for the potential connection of an awning light
(does not illuminate if towing vehicle is connected or ignition is switched
on, installation dependent, also see ”Automatic shutdown for awning
light”)
F230V supply and 230V consumers
The flat vehicle fuses protect the various circuits (12V).
The effectiveness of this function depends on the socket assignment on the
towing vehicle:
FOption 1: Control via the ignition
If the caravan is connected to the towing vehicle, and as soon as the
ignition is switched on (voltage on terminal 10 and tow-bar (AHK)),
circuit 5 provided for the awning light is disabled.
FOption 2: Control with connection to the towing vehicle
As soon as the caravan is connected to the towing vehicle (voltage on
terminal 10 and tow-bar (AHK)), circuit 5 provided for the awning light
is disabled.
This always prevents the awning light from being switched on whilst the ve-
hicle is moving.
All consumers together may not exceed the following load:
FBattery mode: 30 A
FOperation with towing vehicle, ignition ON: 15 A (also see fuse in the
vehicle)
Any 12V battery or rechargeable 12V battery (depending on charger used)
The main 12V switch (rocker switch with centre position) disconnects all of
the 12V consumers from the caravan battery.
This prevents the battery from slowly discharging due to closed circuit cur-
rents.

A closed circuit current of approx. 0.15 A flows for consumers that are swit-
ched off.
No closed circuit current for switched off consumers.
5Maintenance
The CV 304 caravan distributor requires no maintenance.
Clean the caravan distributor with a soft, slightly damp cloth and a mild de-
tergent. Never use spirit, thinners or similar substances. Do not allow liquids
to enter the caravan distributor.
