Proper use
The Pure Sine Wave Inverters convert 12 V (SWI 250-12) or 24 V (SWI 250-24) direct current
to a 230V alternating current at a frequency of 50 Hz.
Warning!
Reverse polarity connection of the battery wires can damage the inverter.

Technical description
The power inverter DC-AC SWI 250 with USB terminal are designed for rated wattage of
electrical use.
The inverter series can be used to operate laptops, most small TVs, VCRs, sound systems and
small handy tools, and other portable sensitive electronic products.
The output voltage corresponds to the socket standard (pure sine-voltage)
Please observe the values for constant output power and peak output power
(for a max. of 10 min.) As indicated in section „Technical data“on page 14.
Never connect appliance that has a higher power requirement.
Note
Note the electrical driving appliance (such as power drills or refrigerators), that they often
need more power than is stated on the type plate.

Installation instructions
When selecting the installation location, observe the following 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 inside housing, ensure proper
ventilation. At least, keep a free space of 10 cm around the inverter (fig. 4, page 12).
• The air inlets and outlets should not be blocked.
• Installing the inverter on a firm foundation.
