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:

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.
