Scope of delivery

Accessories

The target group for this manual

The electrical installation (chapter “Connecting the inverter” on page 14) is intended for professionals who are familiar with the applicable regulations of the country in which the equipment is to be installed and/or used.

All other chapters are intended for the users.

Intended use

WARNING!

Never use the inverter on vehicles where the positive terminal of the battery is connected to the chassis.

The wave inverter converts direct current into a 230 – 240 V AC supply of 50 Hz or 60 Hz:

12 Vg : DSP1312T, DSP1812T, DSP2312T, DSP3512T
24 Vg : DSP1324T, DSP1824T, DSP2324T, DSP3524T

Technical description

The inverters can be operated wherever a DC connection is available:

12 Vg : DSP1312T, DSP1812T, DSP2312T, DSP3512T
24 Vg : DSP1324T, DSP1824T, DSP2324T, DSP3524T
The lightweight and compact construction of this device allows for easy installation in mobile homes, commercial vehicles or motor and sailing yachts.
The output voltage corresponds to the household voltage from the socket (pure sine wave, THD < 3 %).

Please observe the values for constant output power and peak output power as indicated in the chapter “Technical data”. Never connect devices that have a higher power requirement.

NOTE

Note when connecting devices with an electrical drive (such as power drills and refrigerators), that they often require more power than is indicated on the type plate.

The inverter has various protective mechanisms.

Overvoltage shutdown : The inverter shuts itself off when the voltage exceeds the cut-off value. It restarts when the voltage returns to the restart value.
Undervoltage shutdown : The inverter shuts itself off when the voltage sinks below the cut-off value. It restarts when the voltage rises to the restart value.
Excess temperature shutdown : The inverter switches off when the temperature inside the device or the temperature on the cooling element exceeds a cutoff value. It restarts when the voltage rises to the restart value.
Overloading and short circuit shutdown : The LED on the inverter indicates an operating fault when an excess load is connected or a short circuit has occurred. The fuse in the device must be pressed in again by hand after it is triggered by excess current.

NOTE :The individual values are found in the chapter “Technical data”

The inverter can be operated in the following network configurations:

TN network: The neutral conductor of the inverter is grounded. A downstream safety switch (RCD) must be installed.
IT network : Both phases are insulated. This is suitable for operating one load. If more than one load will be connected a protection plan has to be set up (e. g. insulation monitor).

The network configuration is set via a DIP switch at the device.
The inverters DSP13xxT, DSP18xxT, and DSP23xxT have a connection cable with a socket and plug. The inverter DSP35xxT is directly connected at the terminals via the PG glands.
Due to the phase synchronisation, the inverter adapts to the phase of the AC input voltage. Thereby voltage peaks are prevented when switching from battery to mains.

The inverter is suitable for operating sensitive consumers because the output voltage is a pure sinus wave.
The inverter is fitted with a priority circuit. If an external 230 Vw voltage is available,this will have priority. If no external 230 Vw voltage is connected, then the connected battery will be used as the power supply.

The inverter can be switched to an energy-saving mode to prevent the connected battery from discharging too quickly.
The inverter can be turned on or off using the remote control (accessory).
Additionally, the inverter can be controlled using the energy monitor (accessory).
