Safety note

The instrument is built and tested in accordance with
DIN VDE 0411 part 1/ EN 61010 part 1
DIN VDE 0413 part 1, 2 and 4/ EN 61557 part 1, 2 and 4
and has left the factory in perfectly safe technical condition.
To maintain this condition and to ensure safe operation of the appliance tester,
the user must observe the notes and warnings given in these instructions at all
times. Improper handling and non-observance of the warnings might involve
severe injuries or danger to life.
The instrument may be used only in electrical circuits of over
voltage category IV with a maximum voltage of 600 V between
the conductor and ground.
Only use suitable measuring leads for this. With measurements
within measurement category III or measurement category IV,
the projecting conductive part of a contact tip of the measuring
leads must not be longer than 4 mm.
Prior to carrying out measurements within measurement
category III and measurement category IV, the push-on caps

provided with the set and marked with CAT III and CAT IV must
be pushed onto the contact tips. The purpose of this measure
is user protection.
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. As from an input voltage of 30 V
AC/ DC the warning symbol
the BENNING IT 101, as a warning that a dangerous voltage
is connected. In addition, the red high-voltage indicator
9 lights up.
Before starting the appliance tester, always check it as well as

all measuring leads and wires for signs of damage.
Important! During the insulating resistance measurement,

dangerous levels of voltage may occur in the BENNING IT 101.
Should it appear that safe operation of the appliance tester is no longer possible,
it should be shut down immediately and secured to prevent that it is switched
on accidentally.
It must be assumed that safe operation is no longer possible
- if the instrument or the measuring leads show visible signs of damage, or
- if the appliance tester no longer works, or
- after long periods of storage under unfavourable conditions, or
- after being subject to rough transportation, or
- if the device is exposed to moisture.
In order to avoid danger,
- do not touch the bare probe tips of the measuring leads
- when measuring voltage disconnect the switchable probe
tip from the BENNING IT 101 at first
- plug the measuring leads into the correspondingly
designated measuring sockets on the BENNING IT 101

see Fig. 1: Front tester panel
- when disconnecting the measuring circuit, always
disconnect the voltage carrying measuring cable (phase)
first and then disconnect the neutral measuring lead
- do not operate the BENNING IT 101 in the vicinity of
explosive gases or dust.
Maintenance:
Do not open the tester, because it contains no components

which can be repaired by the user. Repair and service must be
carried out by qualified personnel only!
Cleaning:

Regularly wipe the housing by means of a dry cloth and
cleaning agent. Do not use any polishing agents or solvents!
