Automatic Measurements On The Pv Generator - Benning PV 2 Bedienungsanleitung

8.3 Automatic measurements on the PV generator

The PV generator must not exceed the maximum opencircuit voltage of 1000 V
DC, the maximum short-circuit current of 15 A and the maximum DC power (P
= U x I) of 10 kW.
According to DIN EN 62446, the measurements have to be made for each PV
string.
Measuring at PV strings connected in parallel or contacting at the PV inverter
might involve damages of the BENNING PV 2!
The PV generator must be isolated from the electric power supply! Neither the
positive nor the negative pole of the PV generator must be earthed!
Make sure that all measuring lines are safely connected to the PV generator.
For this, use the enclosed safety measuring lines with PV connector as well as
the safety measuring lines with probe tip and alligator clip!
Never disconnect the connected PV safety measuring lines from the PV
generator during measurement! Disconnection might involve an electric arc
and overload of the BENNING PV 2.
During the insulating resistance measurement, the PV generator is shorted.
Measurement is made between the red 4 mm test socket and the shorted PV
test sockets.
In case DC polarity is wrong or DC voltage is within the range of < 5 V or > 1000
V, it is not possible to make an automatic PV measurement.
