BENNING PV 2

Important information

Before using the BENNING PV 2 please read the detailed operating manual (http://tms.benning.de/pv2) carefully. The BENNING PV 2 should only be used by suitably trained personnel.
The connection to the PV generator is made exclusively in accordance with the connection figure of the operating manual. Disconnect not required tests leads from the BENNING PV 2.
Before the measurement disconnected the PV array from the PV inverter! The PV string under test must not exceed the maximum open-circuit voltage of 1000 V, the maximum short-circuit current of 15 A and the maximum DC power (P = Uoc x Isc) of 10 kW.
The measurements are to be carried out on the individual PV string! It must be ensured that all switching devices and isolating devices are open and that all PV strings are isolated from each other.
Only test a single PV string, never test multiple strings and beware of parallel connections! High levels of capacitance within the circuit under test can cause high currents to flow and may damage the test instrument. Non- observiance will result in damage to the BENNING PV 2!
Disconnect the BENNING PV 2 from the test sample directly after the test.
Do not touch the measuring probes! During insulating resistance measurements, high electric currents might be applied to the measuring probes.
Do not touch any metal parts of the test object during measurement. 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!
Via the 4 mm test leads, voltage measurements on mains supply circuits are possible. Via the 4 mm test sockets, the BENNING PV 2 must be used only in electric circuits of overvoltage category III with max. 300 V AC/DC for phase- to-earth measurements. For this please disconnect the PV 2 PV measuring leads from the PV test sockets before measuring.
Before starting the unit, always check it for signs of damage. Do not use a damaged BENNING PV 2!
Only use measuring leads, which are supplied with the BENNING PV 2.
The BENNING PV 2 is intended for making measurements under dry ambient conditions only.
