The pack contains: Voltage converter, operating instructions
Intended use

The devices of the digital sinus voltage converter series DSW serve for mobile and mains-independent power supply of various
230V AC consumers from a 12V or 24V battery. They are used to operate equipment such as TV and Sat systems, audio
systems, tools, pumps, household appliances, compressors, chargers for mobile phones or laptops easily and flexibly.

The user must ensure that the device is protected against humidity and damp. Any other use than described before may
damage this device; in addition, improper use may result in serious hazards, such as short-circuiting, fire, electrical shock etc.

The entire product must not be modified or converted and the housing must not be opened in any manner whatsoever!

• AC outputs of several power sources may not be connected in parallel! Do not connect AC generators or
mains voltage to the AC output of the voltage converter. This leads to the immediate destruction of the
voltage converter!

• Never open the voltage converter! Even after disconnecting the device from the battery there may be
hazardous voltages in the interior of the device. This is why service and repairs may only be carried out by
authorized and qualified personnel.

Warning: Improper assembly may cause hazardous contact voltages even on the closed device!
Notes on the battery

• If used improperly, lead batteries are a high risk for humans, animals and the environment. Always
observe the safety instructions of the battery manufacturer!

• Lead batteries contain aggressive corrosive acids. Avoid eye and skin contact with liquids from the battery!
Never disassemble lead batteries! Wash the parts of the skin affected thoroughly with water and soap. If
acid enters the eye, immediately flood the eye with running, clear and cool water! Then seek medical help
immediately! If acid contacts your clothing, wash immediately with soap and water!

LED indicators

The LED control indicators 9 (DC input) and 10 (AC output) provide important information on the operating status of your
converter. Both LEDs work independently from one another. I.e., a failure in the DC input area has direct impact on the function
of the AC output; or a failure in the output area affects the input function directly.

Description of functions

The voltage converters of the DSW series are modern, microprocessor-c ontrolled devices which were developed for mobile
power supply. The voltage converters of the DSW series convert lower DC input voltage into higher AC output voltage and thus
allow for the usage of conventional 230V AC consumers on the road.
These devices offer real sinus alternating voltage which allows for a trouble-free operation also of difficult consumers such as
PCs, TV systems and devices with transformers.
Of course, all devices of the DWS sinus voltage converter series are equipped with all necessary safety features which
correspond to a state-of-the-art product.
