1) The average over 3 phases can only be called via the communication interfaces or the user defined display.
2) Optionally calculated for total reactive power (VARtot), reactive power (VARn), or reactive power (VAR1).
3) The unit depends on the settings: User definable unit or "kWh" or "kVARh" for the pulse counter function.
4) The operating hours are available via the bus in seconds. They are displayed in hours on the device display.

Measured variables depending on the connection type
The total set of representable measured variables is restricted by the method of connecting
the device.
A measured value that cannot be indicated because of the connection method is shown on
the display by means of a broken line "----".
The table below shows which measured values can be represented depending on the
connection type.
