The following operations are performed in the distribution board:
Install the digitalSTROM Filters according to installation instructions on the top hat rail and connect electrically with the mains supply.Place the digitalSTROM Filters appropriately close to the digitalSTROM Meters. The length of the electrical lines between digitalSTROM Filter and connected meters must be as short as possible.If additional meters are installed in other sub-distribution units, digitalSTROM Filters must necessarily also be installed.Fasten the screws of the unused connection terminals on the digitalSTROM Filter while doing so.The digitalSTROM Filter must be installed on the primary side of the digitalSTROM Meter. If the filter is located on the secondary side, communication in the digitalSTROM power circuit will be impaired! Install the digitalSTROM Meter according to installation instructions.The arrangement of digitalSTROM Meters must include a distance of 0.5 TE after every third digitalSTROM Meter. If the digitalSTROM Meters are mounted horizontally, the distance must be kept after each device.Disconnect the connections on the output side from the power circuit breaker and connect the digitalSTROM Meter according to installation instructions.The maximum current for the digitalSTROM Meter is 16 A. Install the 24 V DC power supply unit for the digitalSTROM Server according to installation instructions on the top hat rail and connect it electrically. Install the digitalSTROM Server according to installation instructions on the top hat rail and connect it electrically.Make sure the 24 V DC supply to the digitalSTROM Server has the correct polarity! Connecting the dS485 bus cable Wire the bus interconnection between the digitalSTROM Meters according to installation instructions.If a digitalSTROM Server was installed, connect the digitalSTROM Server with the bus cable according to installation instructions.A twisted-pair cable with a cross-section of 0.8 mm2 is used for the dS485® bus interconnection.A maximum of one digitalSTROM Server may be connected to the RS485 bus interconnection!
