Connection To The Battery - Victron energy 12 250 Mode D'emploi

Remote on/off connector
A remote on/off switch can be connected to a two pole connector or between battery plus and the
left hand contact of the two pole connector.
LED diagnosis
A red and a green LED indicate inverter operation and status of the different protections.
To transfer the load to another AC source: the automatic transfer switch
For our low power inverters we recommend our Filax Automatic Transfer Switch. The Filax
features a very short switchover time (less than 20 milliseconds) so that computers and other
electronic equipment will continue to operate without disruption.
Available with different output sockets
Schuko, UK (BS-1363), AU/NZ (3112) or IEC-320 (male plug included)
3. Installation

3.1 Connection to the battery

In order to utilize the full capacity of the product, batteries with sufficient capacity and battery
cables with sufficient cross section should be used. See table:
Minimum battery cap.
Internal DC fuse
Recommended DC cable cross-section (mm
0 – 1,5 m
1,5 – 3 m
Minimum battery cap.
Internal DC fuse
Recommended DC cable cross-section (mm
0 – 1,5 m
1,5 -3 m
The inverters are fitted with an internal DC fuse (see table above for rating). If the DC cable length
is increased to more than 1,5m, an additional fuse or DC circuit breaker must be inserted close to
the battery.
Reverse polarity connection of the battery wires will blow the internal fuse and can damage the
inverter. The internal fuse it not replacable.
3.2 Connection to the load
Never connect the output of the inverter to another AC source, such as a household AC wall outlet
or a generator.
3.3 Remote on/off connector
A remote on/off switch can be connected to the two pole connecter. Alternatively, the left hand
contact of the connector can be switched to battery positive: useful in automotive applications,
wire it to the ignition contact.
Note that also the front switch needs to set to either On or ECO for the inverter to start.
3.4 Configuration
The inverter is ready for use with the factory settings (see specifications), and can be configured
with a computer (VE.Direct to USB interface cable needed), Apple and Android smartphones,
tablets and other devices (VE.Direct to Bluetooth Smart dongle needed).
