9. Commissioning
Before commissioning, clear any content
that may be present on the power meters,
min./max. values or recordings due
to the production process.
9. 1 Connecting the supply voltage
After connecting the supply voltage,
the text “Start up” is shown on the display.
Approximately two to six seconds later,
the device switches to the fi rst measured
value indication.
If no display appears, check whether
the power supply voltage is within the rated
voltage range.

9. 2 Frequency measurement
In order to measure the frequency, at least one
voltage measurement path (L-N) must have a
measured voltage of greater than 10 V.
Only detected frequencies in the range
of 15 Hz to 440 Hz are used for measurement
on the current and voltage measurement
inputs.
9. 3 Connecting the measured voltage
After connecting the measured voltages,
the measured values displayed by
the device for the L-N and L-L voltages
must correspond to those on the voltage
measurement input.
If a voltage transformer factor is
programmed, it must be taken into
consideration for the comparison.
At least one phase (L) and the neutral
conductor (N) must be connected to the
voltage measurement input for measurement.
A measured voltage of greater than 10 Veff
must be present on at least one of the voltage
measurement inputs so that the device can
determine the mains frequency.

9. 4 Phase sequence
Check the direction of the rotating fi eld
voltage in the measured value indication
of the device. A “right-hand” rotation fi eld
usually exists.
