Data Manager
The Data Manager is a measuring instrument that determines electrical measured values at
the connection point and makes them available via LAN or RS485.
The data collected by the Data Manager about power generation in your plant can differ from
the data of the main energy counter.
In accordance with its classification in Overvoltage category III, the Data Manager may only
be connected in the subdistribution board or circuit distribution board on the load side
downstream of the energy counter of the power supply company. It is suitable only for use in
the indoor area, and it is approved for use in the member states of the EU. Use the sensor
bar only in accordance with the information given in the enclosed documentation. Any other
use can result in material damage and personal injury.

Functions
How the individual components of the system function is defined below.
The current sensor of the Data Manager is a current transformer in the ratio 1:1000.
The Data Manager reads out the connected sensor bar at fixed regular intervals and
calculates the active power, the reactive power and the apparent power using the internally
measured voltage U[1,2,3] of the respective phase PI[1,2,3] as well as the power factor (cos
phi).
