Dometic B2200
Other installations are not permitted and may destroy the inverter or the con-
nected device.
6 Technical description
The ECW-012VS inverter consists of two function units:
Inverter switch: generates 230 V power supply from a 12 V battery
Mains priority circuit: switches automatically between 230 V of external
mains voltage (e.g. on a camping site) and a battery generated 230 V
power supply.
The external supply has priority. If no more external voltage is available,
the output socket is disconnected from the external power supply and
connected to the inverter voltage. This ensures that the output socket
always has a power supply of 230 V.
The inverter is equipped with protection against thermal and electrical over-
loading, as well as excess and insufficient voltage. The inverter switches off:
If its internal temperature is too high
If the load exceeds the values listed in the technical data
If the input voltage is too high or too low
