Procedure
1. Connect the PVsafety measuring lines to the device [}page25].
2. Bring the PVsafety measuring lines into contact with the first PVstring of the PVgenerator.
Make sure that the respective safety measuring lines are contacted properly and safely with
the PVgenerator.
If DCvoltage is applied to the PVsafety measuring lines, the PVopen-circuit voltage will be
measured automatically.
3. Connect the red 4mm safety measuring line to the device [}page25].
4. Bring the red 4mm safety measuring line into contact with a metal part (frame or mounting
system) of the PVgenerator.
If the PVgenerator is properly earthed, you can alternatively measure the insulating
resistance against a safe earth connection (e.g. equipotential busbar).
If the PVgenerator is not earthed, first measure the insulating resistance against a metal
part (frame or mounting system) of the PVgenerator and then against a safe earth
connection (e.g. equipotential busbar).
5. Select the desired insulation test voltage of 250V‑DC, 500V‑DC or 1 000V‑DC. To do this,
press the “V
ISO
“key until the desired insulation test voltage is shown on the digital display.
6. Start the automatic PVmeasurement. To do this, press the “Auto”key.
7. Press the “Save”key to store the measured value to the next free storage location available.
8. Repeat this procedure for all identical PVstrings.
After completing the test, you can check in the measured value memory whether the
measured values are identical and within the maximum deviation range of 5%.
5.9 BENNINGSUN2 (optional)
5.9.1 Pairing the device with the BENNINGSUN2
Requirements
• BENNING SUN2 (optional accessories)
• Please observe the specifications given in the operating manual of the BENNINGSUN2.
• Make sure that there are no electric devices in direct vicinity.
Procedure
1. Switch off both the device and the BENNINGSUN2.
2. Simultaneously press and hold the two keys “Temperature” and “Angle of inclination” of the
BENNINGSUN2 as well as the two keys “R
PE
” and “Auto” of the device for approx.
2seconds until the two devices are paired.
The device indicates the successful pairing via an acoustic signal and shows the serial
number of the paired BENNINGSUN2 as well as the “W / m²”symbol on the digital display.
The pairing remains enabled until the devices are unpaired.
