BENNING PV 1-1
Important information
m
Before using the BENNING PV 1-1 please read the detailed operat-
ing manual (http://tms.benning.de/pv1-1) carefully.
The BENNING PV 1-1 should only be used by suitably trained per-
sonnel.
c
The connection to the PV generator is made exclusively in accord-
ance with the connection figure of the operating manual.
Disconnect not required safety tests leads from the BENNING PV 1-1.
c
Before the measurement disconnected the PV array from the PV
inverter!
The PV string under test must not exceed the maximum open-cir-
cuit 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 1-1!
c
Disconnect the BENNING PV 1-1 from the test sample directly after
the test.
c
Do not touch the measuring probes! During insulating resistance
measurements, high electric currents might be applied to the meas-
uring probes.
c
Do not touch any metal parts of the test object during measure-
ment.
c
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!
c
Via the 4 mm safety test leads, voltage measurements on mains
supply circuits are possible. Via the 4 mm test sockets, the
BENNING PV 1-1 must be used only in electric circuits of overvolt-
age category III with max. 300 V AC/DC for phase-to-earth measure-
ments. For this please disconnect the PV 1-1 measuring leads from
the PV test sockets before measuring.
c
Before starting the unit, always check it for signs of damage. Do not
use a damaged BENNING PV 1-1!
m
Only use safety measuring leads, which are supplied with the
BENNING PV 1-1.
c
The BENNING PV 1-1 is intended for making measurements under
dry ambient conditions only.
