Safety note

The instrument is built and tested in accordance with
DIN VDE 0404 part 1 and 2
DIN VDE 0411 part 1/ EN 61010 part 1
DIN VDE 0413 part 1/ EN 61557 part 1, 2, 4 and 10
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. Improper handling and non-
observance of the warnings might involve severe injuries or danger to life.
WARNING! Be careful when working with bare conductors or main line carrier!

Contact with live conductors will cause an electric shock!
The BENNING ST 720 may be used only in power circuits within the overvoltage
category II with a conductor for 300 V AC 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.
The device must be connected to a single-phase mains with 230 V, 50 Hz,
pre-fuse 16 A only. Please make sure not to exceed the maximum breaking
capacity/ lamp load of the test socket of the BENNING ST 720 (see chapters 7.4

and 7.5). Exceeding the values might cause tripping of the fuses and damaging
of the BENNING ST 720. Damages due to overload are excluded from possible
warranty claims.
Do not carry out repeated protective conductor or contact current
measurements with a measuring duration of 30 seconds at test objects with

high current consumption (16 A). Repeated measurements at maximum load
(16 A) might heat up the inside of the device and thus also its surface.
The protective conductor resistance measurement might be distorted by
impedances connected in parallel of additional operating circuits and by

transient currents.
Measurements of the protective conductor resistance and of the insulating
resistance must be carried out at idle system parts only.

Before starting the appliance tester up, always check it 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:
- if the instrument show visible signs of damage
- if the appliance tester no longer functions
- 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
- do not touch the bare measuring probe tips of the measuring lines,

- plug the lines into the correspondingly marked jacks at the measuring
instrument
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!
