1 | Installing and connecting the digitalSTROM Filter | Install the digitalSTROM Filters according to the installation instructions on the top hat rail and connect electrically with the mains supply. Position the digitalSTROM Filter correspondingly close to the digitalSTROM Meter. The cable length of the electrical connection between the digitalSTROM Filter and the digitalSTROM Meter must be kept as short as possible. If additional digitalSTROM 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! |
2 | Installing and connecting the digitalSTROM Meter | Install the digitalSTROM Meter according to the installation instructions. Distances 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. Heat dissipation at high load and increased ambient temperature will be improved by this. ![]() Connection Disconnect the connections on the output side from the power circuit breaker and connect the digitalSTROM Meter according to the installation instructions. The digitalSTROM Meter is connected in series with the power circuit breaker. The maximum current for the digitalSTROM Meter is 16 A. |
3 | Installing and connecting the power supply unit (option) | Install the 24 V DC power supply unit for the digitalSTROM Server according to the installation instructions on the top hat rail and connect it electrically. The used power supply unit must have a rated voltage of 24 V DC +/-10 % and a minimum current of 0.4 A. Country-specific regulations must be complied with during assembly and wiring of the power supply unit. |
4 | Installing and connecting the digitalSTROM Server (option) | Install the digitalSTROM Server according to the 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! |
5 | Connecting the Ethernet interface (option) | Connect the Ethernet interface to a local network (router). |
6 | Connecting the dS485 bus cable | Wire the bus interconnection between the digitalSTROM Meters according to the installation instructions. If a digitalSTROM Server was installed, connect the digitalSTROM Server with the bus cable according to the installation instructions. Make sure the connection terminals for the bus interconnection have the correct polarity! A twisted-pair cable with a cross-section of 0.8 mm2 is to be used for the dS485® bus interconnection. A maximum of one digitalSTROM Server may be connected to the RS485 bus interconnection! Terminating resistors: Make sure that the enclosed terminating resistors are connected at both ends of the bus interconnection! |
