Safety note

The instrument is built and tested in accordance with
DIN VDE 0411 part 1/ EN 61010-1
DIN VDE 0411 part 2-032/ EN 61010-2-032
DIN VDE 0411 part 031/ EN 61010-031
and has left the factory in perfectly safe technical condition.
To maintain this condition and to ensure safe operation of the unit, the user must observe the
notes and warnings given in these instructions at all times. Improper handling and non-obser-
vance of the warnings might involve severe injuries or danger to life.
WARNING! Be extremely careful when working with bare conductors or main

line carrier! Contact with live conductors will cause an electric shock!
The BENNING CFlex 2 may be used only in electrical circuits of over voltage
category IV with a maximum voltage of 600 V or of over voltage category III

with a maximum voltage of 1000 V between the conductor and ground.
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 unit, always check it as well as all measuring lead and
wires for signs of damage.
Should it appear that safe operation of the unit is no longer possible, it should be shut down
immediately and secured to prevent that it is switched on accidentally.
It may be assumed that safe operation is no longer possible:
- if the device or the measuring lead exhibit visible damages,
- if the unit no longer works,
- after long periods of storage under unfavourable conditions,
- after being subject to rough transportation, or
- if the device or the measuring lead are exposed to moisture.
