2. General Information
The static transfer switch STS207 is designed for a nominal switching capacity of 7kVA and is used for
nearly interruption free switching (<4 ms) between two AC sources (usually inverter and substitute-
mains supply). It is intended for the operation in combination with inverters of series INV215/222. Con-
sequently AC consumer loads can be driven nearly without interruption if one of the two power sources
fails.
The STS207 is a hot plug-in module with rear side connectors and is designed to be mounted in an
assembly set sub rack (see section 3.2).
The operation and indication elements as well as an Ethernet and CAN-Bus connector are user-friendly
integrated in the front plate of the unit.
