The devices are connected between the grid connected, decentral electrical energy source such as photovoltaic systems, wind turbines, block-type thermal power stations, and the public grid. In case the public grid is disconnected due to any reason, for instance during maintance work, the CM-UFS.1/CM-UFS.1x recognize this powerless situation. Then, in conjunction with a switching device, the CM-UFS.1/CM-UFS.1x disconnect the decentral electrical energy source from the public grid. The devices detect overvoltage and undervoltage (voltage increase and decrease protection) as well as any changes in grid frequency (frequency increase and decrease protection) in accordance with DIN V VDE V 0126-1-1 and DIN V VDE V 0126-1-1/A1 VFR 2013 / VFR 2014. The connection of the neutral conductor is configurable. The threshold value for the 10 minutes average value is adjustable. The CM-UFS.1/CM-UFS.1x are also suitable for monitoring single-phase mains. For this, all three external conductors (L1, L2, L3) have to be jumpered and connected as one single conductor.
