BENNING ST 750 A

6. General Information / Technical Specifications

The BENNING ST 750 A Appliance Tester is provided with a touchscreen and a switchable test

socket.Thebuilt-inUSBinterfaceandthe"BENNINGPC-WinST750"PCsoftwareallowread-out

of the memory data as well as communication between PC and tester. The BENNING ST 750 A is

intended to be used for safety tests of electrical appliances after

- repair, modification and periodic inspection of electrical appliances (DIN VDE 0701-0702)

- periodic tests and after repair of medical electrical devices or systems (DIN EN 62353; VDE

0751-1; IEC 62353).

The DIN VDE 0701-0702 standard applies to tests regarding the electrical safety of electrical ap-

pliances with rated voltages of 1000 V AC / 1500 V DC. The standard shall apply together with the

test procedures and tests to be applied for proving the electrical safety by observing the admissible

limitingvalues.Thisstandardshallalsoapplytotestsafterrepair,modicationandperiodictests

ofelectricalapplianceswhichare rmlyconnectedtotheelectricalsystemorwhichareportable

devices.Theresponsible qualied electrician shalldecidewhetheranelectricalappliance which

isrmlyconnectedtothesystemshallbetestedduringperiodictestingtogetherwiththesystem

according to DIN VDE 0105-100 (VDE 0105-100) or whether it shall be tested according to this stan-

dard, but separate from the system or together with a part of the system. Electrical appliances which

arenormallyconnectedbymeansofaplugconnection,butexceptionallyarermlyconnected,shall

be tested according to DIN VDE 0701-0702. For testing a system, it shall be allowed to disconnect

the connected devices and to test them separately according to DIN VDE 0701-0702. The standard

shallnotapplytodevicesforwhichspeciclaws,provisions,operatingmanualsorregulationshave

to be observed ( e.g. explosion hazard areas, mining etc.). Test samples with three-phase connec-

tion shall be tested by means of a corresponding adapter and a separate leakage current clamp.

The measuring results shall be entered manually into the appliance tester for joint logging. The tests

shall be carriedoutby competent persons,qualied electricians orbyelectrotechnically trained

personnelundersupervisionofqualiedelectricians.

§ 5 of BGV A3 (BGV A2 (VBG 4)) says:

1. The company shall ensure that electrical systems and equipment are tested with regard to

their proper condition:

- before initial commissioning and after modification or repair, before recommissioning

by a qualified electrician or under supervision of a qualified electrician, in defined time

intervals.

- The intervals shall be determined in such a way that assumable occurring defects can be

detected in good time.

2. For testing, the corresponding electrotechnical rules shall be observed. On request of the

professional association, a test book with certain entries shall be kept.

7. Commissioning / Setup



Important system settings (expert settings) can only be made by trained service

specialists by entering a password!

Remove SD memory cards only with the appliance tester being switched off!

Before switching the device on, remove all test cables from the appliance tester

and reconnect them only after having carried out a self-test.

For commissioning:

- Connect the mains connection cable to

the shock-proof socket (230 V, 50 Hz,

16 A).

-Setthemainsswitchtoposition"I".

- The Appliance Tester carries out a self-

testandafterrun-upshowsthermware

version in the upper line of the display.

- After run-up, press the <Setup> button.

7.1 Battery-operated user interface

The BENNING ST 750 A Appliance Tester is equipped with an integrated storage battery for main-

taining the function of the user interface in case of a mains power failure. Thus, for a short time, the

device can be carried from one place of inspection to another without requiring mains voltage and

without being switched off before. Moreover, it is still possible to access the SD card to open or edit

databases. It is not possible to carry out electrical tests in battery operating mode.

When the device is operated without mains voltage, the following information is shown on the dis-

play depending on the battery charge condition:

Assoonas"Batterywarninglevel2"isshownonthedisplay,immediatelyconnectthedevicetothe

mains voltage in order to charge the storage battery. The storage battery will be charged automati-

cally in mains operating mode with the device being switched on.
