13. Commissioning
13.1 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 mea-
suring display
Home
appears on the display of
your measurement device.
3. If no display appears, check whether the sup-
ply voltage is within the nominal voltage range.
13.2 Measured voltage
NOTE
In networks with nominal voltages that exceed the
specified nominal voltages, connect the voltage
measurement inputs via voltage transformers (see
section „7.1 Nominal voltages“ on page 22)!
Connect measured voltage:
1. Connect the measured voltage to the termi-
nals of the voltage measurement inputs on the
back of the device.
2. After connecting the measured voltage, check
the measured values displayed by the device
for the voltages L-N and L-L.
Take into account any voltage transformer
factors that may be set!
NOTE
Before commissioning, delete any production-re-
lated contents of the energy meters, min. and max.
values and recordings (see the section „Minimum
and maximum values“ on page 45)!
CAUTION
Material damage due to disregard of the con-
nection instructions!
Disregard of the connection instructions can dam-
age or destroy your device.
Observe the following:
·
Observe the voltage and frequency specifi-
cations on the rating plate!
·
Do not use the device for measuring DC
voltage!
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.
13.3 Measured current
The device:
·Is designed for the connection of current trans-
formers with secondary currents of ../1 A and
../5 A.
·Does not measure DC currents.
The factory-set current transformer ratio is 5/5 A
and must be adapted to the current transformers
used as needed.
1. Short-circuit all current transformer outputs
except one.
2. Compare the current displayed on the device
with the applied input current.
- The currents must match after taking the
current transformer ratio into account.
- In the short-circuited current measurement
inputs, the device must indicate approx. 0
amperes.
