To ensure that all 12V electronic devices work without external power, the camping battery voltage should never fall below 12V (50%).
The light in the Couple Cottage (Bürstner Lineo/Signeo) only works when the camper battery is charged or when an external power supply is connected.
Switch on the Camper Unit at the sliding door to be able to use light and power:
The light switches for the interior are located at the kitchen counter and in the bathroom:
The light switch for the awning light is located on the back of the passenger seat, next to the switch for the step:
The LED reading spots and LED strip below the cupboards can be operated via buttons directly on the light:
There are numerous power sockets and USB ports throughout the vehicle:
- 230V sockets can be found underneath the table and at the kitchen unit
- USB ports (USB Type-B) and 12V sockets can be found in the cockpit (in the centre console and in the compartment above the steering wheel), on the kitchen block and in the shelf next to the door to the bathroom. These also work without an external power connection.
Please note the following:
- When stationary, do not charge any device in the driver's cab via USB. The starter battery will discharge and the engine may not start!
- 230V sockets: only work with an external power connection
- USB ports and 12V sockets: work without an external power connection, with a charged camping battery (always keep it above 50% or 12V).
- With a full battery, you can be self-sufficient for 1-2 days without a power connection, depending on usage. Then you need to drive for a while to recharge the battery or connect your camper to an external power source.
- 🚗 Slow driving & short distances → hardly any battery charge
- 🛣️ Long drives on motorways → better charge, but takes several hours
- 🔋 The starter battery is charged first, then the camping battery.
- ⚠️ Driving alone is often not enough to fully charge the camping battery.
- 🔌 Recommendation: charge externally every 48 hours to avoid energy shortages (especially at night 💤).
- Don't forget to unplug the power cable before driving off! For some models, you need to press the blue lever next to the plug downwards.
Troubleshooting
If the power or light does not work, you can test several things:
- Check whether the camper unit is switched on.
- Check the charge level of the camper battery.
- If there is no power at all in the camper, check whether the "Batterie-Trenn-Schalter" is set to "EIN = On". You will find this under the mattress at the foot end, under a wooden cover:
- Check the main fuse of the camping battery. It is located in the luggage compartment in the rear left cupboard. It is the 40A fuse here:
Before any fuse is pulled, following safety measures is required:
- Turn off the engine and remove the key from the contact.
- Unplug the car from any external power supply.
- Pull carefully on the fuse by pulling from the sides.
- A damaged fuse can be burnt or have the connector broken (see picture). If so, please replace it. You can find them at petrol stations and hardware stores.
When connected to shore power
- The motorhome indicates that the battery is being charged via external power by a light coming on at the top left of the Camper unit (van symbol).
- If you are connected to the outside current (230V) and have problems, check whether the RCD or another of the 230V fuses has jumped out. They must be tilted up for them to work. The small windows must light up red.
You will find them behind a flap on the side of the rear seat, in a white plastic box: - If everything is OK, check if the cable or the socket at the other end (which is plugged in at the campsite) is defective. Maybe a nice fellow camper will let you check with his cable and his working socket?
