Also a 230 volts on-board supply with several sockets can be obtained in camping
caravans, commercial vehicles or motor and sailing yachts, whereby the valid regulations
for electrical safety must be adhered to. With its low weight and the compact design, the
inverter can be easily installed also in small vehicles. With consumer units with high
starting current, the starting capacity of the device to be connected has to be calculated
when dimensioning the inverter capacity.
General installation instructions!
The inverter has to be installed in a dry and clean place not exposed to humidity. Make
sure that the place is well ventilated. If installed into housing, ensure proper ventilation. At
least, keep a free space of 10 cm around the inverter. The air intake at the bottom of the
inverter and the air outlet on the back may not be blocked. With ambient temperatures
higher than 40 °C (e.g. motor- or heating rooms, direct solar radiation), the continuous
output reduces as specified in the technical specifications. The installation surface must
be level and of sufficient strength. In case of drilling, leave enough space for out-coming
bits.
The priority circuit differentiates between two voltage sources:
1. External mains voltage e.g. from the camping site
2. 230 volts voltage generated out of the battery.
The inverter has an input socket for 230 V and an output socketfor 230 V. The inverter
generates out of the battery voltage a 230 V alternating voltage which is switched at the
output socket even when no external voltage is connected or is available. The external
voltage is always switched to the output socket as priority. Only if an external voltage is
not anymore present, then the socket will be disconnected from the external voltage
circuit and connected with the voltage circuit of the inverter. Thus it is ensured that a 230
V voltage is always applied to the output socket. A wiring of the external voltage with the
inverter-voltage can be excluded.
