Functional Description
The SWD series converters are modern, micro-processor-controlled devices developed for mobile
power supply. The converters convert 12 or 24 V/DC input voltage into a higher AC output voltage
depending on type, thus enabling operation of conventional portable 230V/AC consumers.
These devices offer true sinus alternate voltage, which makes it possible to even operate so-called difficult
consumers such as computers, TV systems and devices with converters or motors without any problems.
All SWD series devices are equipped with all required safety features required for a modern product.

DC Connection
Use cables that are as short as possible and with sufficient cross-section for the connection of the DC
line and ensure good contact both at the battery and the converter.
Too think or loose connections can cause fire due to overheating!
The operating switch (11) at the front of the device must be set to “OFF” (Position 0).
A high-current fuse must be installed right at the battery. If this fuse is not there, short-circuits at the two
connection cables may cause fire.

Charging the large capacitators inside the converter may cause a spark upon
connection of the fuse. This device is completely harmless.
The input voltage may not exceed the stated range (see technical data)!
In case of reversed polarity, the converter cannot be put into operation. Connect
it in correct polarity.
