Instruction manual caravan distributor CV 304 with switch panel
6
Stand: 24.06.2016 8120065 BA / EN
The CV 304 caravan distributor contains:
F the complete 12V distribution unit
F the fuses for the 12V circuits
F the 230V distribution unit
F Space 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:
F Three circuits each with 10 A max.
F One circuit (max. 5 A) for a water pump. This circuit is enabled/disabled
with the pump switch.
F Another 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”)
F 230V 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:
F Option 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.
F Option 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:
F Battery mode: 30 A
F Operation 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.
