Benning PV 3 Bedienungsanleitung Seite 17

c
Disconnect the BENNING PV 3 from the PV generator directly after the test. The tester
is not designed to be permanently operated on the PV generator.
WARNING! Be careful when working with bare conductors or main line carrier! Contact
c
with live conductors will cause an electric shock!
Remember that work on electrical components of all kinds is dangerous. Even low volt-
ages of 30 V AC and 60 V DC may be dangerous to human life.
c
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!
c
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).
c
Always wear personal protective equipment (PPE) when connecting or disconnecting
the measuring lines!
Use the BENNING PV 3 only in compliance with the intended use specified in this docu-

mentation. If the Benning PV 3 is used in a manner not specified by this document then
the protection provided by the equipment may be impaired.
c
Use the BENNING PV 3 under dry ambient conditions only.
Before opening the battery compartment, all measuring lines must be removed!
c
Electrical danger!
Before commissioning, the battery compartment must be properly closed.

Do not use pointed objects to remove the rechargeable batteries from the BENNING PV
3. Damaged batteries can leak and increase the risk of fire!
Only use rechargeable 3.7 V 18650 lithium-ion batteries (accumulators, protected ver-

sion). Unprotected 18650 lithium-ion batteries increase the risk of leakage and damage
to the BENNING PV 3.
If it is assumed that safe operation is no longer possible, the device must be switched off immediately and
secured against unintended operation.
It may be assumed that safe operation is no longer possible:
- if the instrument show visible signs of damage
- if the appliance tester no longer functions or a warning is shown on the display,
- after long periods of storage under unfavourable conditions
- after being subjected to rough transport
- the device is exposed to moisture.
In order to prevent danger
c
- do not touch the bare measuring probe tips of the measuring leads,
- plug the leads into the correspondingly marked jacks at the BENNING PV 3

Do not open the device! Apart from the rechargeable batteries, it does not contain any
components requiring maintenance by the user. Repair and service must be carried out
by qualified personnel only!
