DIN VDE 0411 part 1/ EN 61010-1
and has left the factory in perfectly safe technical state.
To maintain this state and ensure safe operation of the appliance tester, the user
must observe the notes and warnings given in these instructions at all times.
The BENNING CM 4 may be used only in power circuits within
the overvoltage category III with a conductor for 600 V max.

to earth. 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 as well

as all cables and wires for signs of damage.
Should it appear that safe operation of the appliance tester is no longer possible,
it should be shut down immediately and secured to prevent it being switched
on accidentally.
It may be assumed that safe operation is no longer possible:
