Digital Sinus Inverter 12V/24V
DSW-2000S (synchronous)
Brief description of the synchronous version:
Two DSW-2000S inverters are connected in parallel via an additional connection socket and synchronised to achieve a
permanent output of 4000 W. Please use only the synchronous cable supplied by the manufacturer.
The inverter DSW-2000S can be operated by remote control.
The two inverters can also be operated individually with the respective continuous output of 2000 W.
All of the other features and operation elements correspond to the DSW-2000, and were described in detail at the start of these
operating instructions.

Connection of the DSW-2000S
In order to ensure a correct start-up, make sure to read these operating instructions and the safety warnings thoroughly and
attentively, and to observe these accordingly.
• Connect the two DSW-2000S units with the aid of the synchronous cable, as shown in Figs. 1 and 2.
• Use the shortest possible cable with an adequate cross section for the DC line, and make sure there is a good contact
at the battery and at the inverter.
• The recommended minimum cable cross section of connections cables for the DSW-2000S is 35 mm² for cable
lengths of 2 metres and 50 mm² for a cable length of 3 metres. Please see also the section “Recommended
minimum cable cross sections for connection cables”.
• Attention! Cables which are too thin, or loose connections can lead to fire due to overheating!
• The switch 8 on the front of the device must be at the “Off” position.
• A high current fuse must be installed directly at the battery. If this fuse is missing, a short circuit of the two connection
cables can cause a fire.
• Now connect both cables to the battery (plus pole = red; minus pole = black).
• Attention! The charging of the large capacitors inside the inverters can cause a spark when the fuse is connected.
This is completely harmless.
Starting up
• Before starting up, always check the inverter for possible damage. If there is damage, do not start the device, but
contact an authorised expert or our service department.
• Always make sure that the inverter is adequately ventilated. Never cover the ventilation slots on the inverter. Do not
operate the device in the proximity of easily flammable materials.
• Set up the inverter in such a way that it cannot tilt or fall over.
• Mount the inverter in such a way that it is inaccessible to children. Risk of death!
• Check the voltage requirements of the consumers to be connected. Only connect consumers whose voltage and
current specifications match those of the inverter. Do not connect any defective or damaged consumers.
For further information on the operation and the individual functions of the device, please see the sections “Operation”
and “General Instructions for the operation of AC consumers with inverters“
