12. Commissioning
In this section you will learn everything needed for
the initial commissioning of your device.
12.1 Supply voltage
Proceed as follows when applying the supply
voltage:
1.Connect the supply voltage with a terminal on
the back of the device.
2.After connecting the supply voltage, the first
measuring display "Home" appears on the dis-
play after approx. 15 seconds.
3.If no display appears, check whether the supply
voltage is within the nominal voltage range.
WARNING
Material damage due to disregard of the con-
nection instructions!
Voltages and currents outside the permissible
measuring range can destroy the device.
· Comply with the measuring range specifica-
tions from the technical data.
· Do not use the device for measuring DC
voltage!
INFORMATION
Before commissioning, delete any possible pro-
duction-related contents of the energy meters,
minimum and maximum values and records.
12.2 Measured voltage
Connect voltage measurements in networks with
nominal voltages above 500 VAC to ground using
voltage transformers.
Proceed as follows to connect the measured
voltage:
1.Connect the measured voltage using a terminal
on the back of the device.
2.After the measured voltage is connected, the
measured values displayed by the device for the
voltages L-N and L-L must match those at the
measurement input.
3.Take into account any voltage transformer fac-
tors that may be set.
WARNING
Risk of injury due to electrical voltage!
If the device is exposed to surge voltages above
the permissible overvoltage category, safety-rele-
vant areas of insulation in the device can be dam-
aged. This means that the safety of the product
can no longer be guaranteed.
Only use the device in environments in which
the permissible overvoltage category is not
exceeded.
