13. Commissioning
13.1 Connecting supply voltage
1. Connect the supply voltage with a terminal on
the rear of the device.
2. After connecting the supply voltage, the
measured value display “Overview” appears
on the screen.
3. If no screen appears, check whether the
supply voltage is within the rated voltage
range.
13.2 Measured voltage
Voltage measurements in lines with rated voltage
exceeding the maximum specified rated voltage
(see chapter 6.2
“Rated voltaies”
) must be
connected using voltage transformers.
Connect the measured voltage:
1. Connect the measured voltage with a terminal
on the rear of the device.
2. After the measured voltage has been
connected, the measured value displayed
by the device for voltages L-N and L-L must
match those at measurement input.
3. You may need to account for the set voltage
transformer factors.
NOTE
Before commissioning, delete possible
production-related contents of the energy
meter, the min./max. Values and recordings.
CAUTION
Property damage due to noncompliance
with the connection conditions.
Noncompliance of the connection conditions
can damage or destroy your device.
Therefore, please observe the following:
·
Observe the specifications on the
nameplate relating to voltage and
frequency.
·
Do not use the device to measure DC
current.
WARNING
Risk of injury due to electric voltage!
If the device is subject to impulse voltages
exceeding the permissible overvoltage
category, safety-relevant insulations in the
device may suffer damage. As a result,
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.
13.3 Measured current
The device:
·is designed for the connection of current
transformers with secondary currents of ../1 A
and ../5 A.
·does not measure DC currents.
·features current measurement inputs that can
be loaded with 60 A (sinusoidal) for 1 second.
The default current transformer ratio is set to
5/5 A and may need to be adjusted to the current
transformer used.
1. Short circuit all current transformer outputs
except for one.
2. Compare the current displayed on the device
with the applied input current.
- The currents must match allowing for the
current transformer transformation ratio.
- The device must display approx. 0 amperes
in the short circuited current measurement
inputs.
