BENNING PV 3
1. User notes
Please read the detailed operating manual (see section 6.1) before operating the PV tester!
This operating manual is intended for qualified technical personnel! Qualified technical
personnel is competent to identify risks and to prevent possible hazards. Improper han-
dling involves the risk of injury! Always wear personal protective equipment (PPE) when
carrying out the test.
Warning of dangerous electric voltage!
Absolutely observe all safety instructions!
2. Safety notes
The connection to the PV generator is made exclusively in accordance with the connection
figure of the operating manual. Only use the included PV measuring leads or the measuring
leads with attached alligator clips for safe contacting of the PV generator.
The PV generator must be isolated from the electric power supply (PV inverter)!
The PV module/PV string must not exceed the maximum opencircuit voltage of 1500 V DC,
the maximum short-circuit current of 40 A and the maximum DC power (P = U x I) of 45 kW.
Measuring at PV strings connected in parallel might involve damages of the BENNING PV 3!
Do not disconnect any measuring leads from the PV generator as long as the test is being
carried out. Failure to do so might result in a dangerous electric arc or damage to the
BENNING PV 3!
The BENNING PV 3 must not be switched off during the test.
The PV test sockets
8
and
9
are intended exclusively for the connection with PV genera-
tors (PV module, PV string, PV field).
WARNING! Be careful when working with bare conductors or main line carrier! Contact with
live conductors will cause an electric shock!
Remember that work on electrical components of all kinds is dangerous. Even low voltages
of 30 V AC and 60 V DC may be dangerous to human life.
Before starting the appliance tester up, always check it for signs of damage. Do not use a
damaged BENNING PV 3! Damaged measuring leads must be replaced!
Only use safety measuring leads, which are supplied with the BENNING PV 3.
The included measuring leads are designed for 1500 V systems which are insulated from the
main electric supply (PV inverter).
Always wear personal protective equipment (PPE) when connecting or disconnecting the
measuring leads!
