www.g-mw.de14
6 Testing the electrical connection
The operator is responsible for the safety of the electrical installation (incl. on-site electrical connection
and equipotential bonding system), in accordance with the fundamental statutory regulations
(accident prevention regulations, valid standards).
Testing the electrical connection is not part of the test requirements for modication, testing and repeat
testing on the electrical devices. In spite of this, it is still important to know that the mains status is OK
before testing electrical appliances.
The test device does not test the electrical connection as required by DIN VDE 0100.
However, it does make important and meaningful measurements for the electrical connection, e.g.:
• Testing the mains protective earth conductor potential via the nger contact
• Mains protective earth conductor potential PE < 30 V
• Testing the N conductor for disruptions (display stays o)
• Display of the phase control lamp when the relay is activated
• Measurements of voltage phase to N (display 1 bis 260 V AC)
Note:
• First, check whether the protective earth conductor is connected by touching the nger contact.
If the red LED ashes, the protective earth conductor is not connected. ‘PE>30V!!’appears on the
display if the protective earth conductor connection is not OK. The device also emits a short audible
warning signal.
• Measurements with the test device can only be performed again after the protective earth
conductor has been repaired successfully.
• If N/PE are mixed up, the on-site fault-current circuit breaker disconnects.
• If there is no display, there may be voltage present at PE. Test the appliance using the nger contact,
disconnect the test device from the mains and check it in another socket. If the appliance works now,
have the socket checked by a specialist.
• When used in an IT network, and if the test device is connected via an isolating transformer, there
is no PE connection: The following message is shown on the display:„PE > 30V!!“.
Note!
The designations described here could dier by
device, operating system and software version!

www.g-mw.de 15
6.1 Display connection
The rst menu,„Connection“, shows the mains voltage present and the quality of the N and PE conductor
connection.
You can check that the nger contact LED is working properly by touching the nger contact in the
individual measurement„IEA LN - Probe“ with the probe. The LED must ash.
6.2 Single-phase connection
WARNING!!!
• If voltage L1 < 207 V, or L1 > 253 V, reliable and meaningful measurements are no longer possible!
If the message ‘PE>30V!!’is shown, there is probably a disruption in the protective earth conductor or
there may be an external voltage at the protective earth conductor (check with the nger contact)!
See„Checking the electrical connection“ on page 13 for details of how to check the protective earth
conductor.
7 Commissioning the test device
7.1 Performing a visual inspection
• See the safety instructions in Section 1!
• Visually inspect the mains connection, test device and measurement accessories!
• Heed warnings on the test device, mains adapter cable and measurement accessories!
7.2 Supplying the test device with mains voltage
The test device is supplied via the mains connection on the top of the device.
The TG Basic 2 and TG Basic 2+ devices are automatically deactivated completely after approx. 10 min.
Important note! For the TG Basic 2+ tester:
The rechargeable batteries are fully charged after approx. 5 hours of charging.
The rechargeable batteries must be fully charged before commissioning for the rst time!!!
The device can only be charged when it is switched o.
The charging process is indicated by a ashing red LED.
There is no automatic deactivation if the device is in remote mode (Test-Master app).

www.g-mw.de16
The Ni-MH batteries can be aected by a memory eect. To counteract this, you should discharge the
batteries completely roughly once a month.
• The„Discharge battery“ function can be found on the Connection menu of the TG Basic 2+.
• Press the button to start the discharge process; the screen switches o, the relays switch on and
the red LED ashes. The charging process starts automatically as soon as the batteries are completely
discharged
• The maximum discharge period is 5 hours
• The maximum charge period is 10 hours
The device must be supplied with power at all times during the discharging and charging process!
• When the device has been charged 20 times (without previously discharging it fully), a message
appears prompting you to discharge the battery.
Display of the charging state: ‘Charge!’is shown on the display when the device needs charging.
7.3 Starting the test
The individual tests can be selected via the direct selection buttons. Optionally, tests can be performed
automatically via the Bluetooth connection using the Test-Master app in remote mode.

www.g-mw.de 17
8 Testing electrical appliances
The tests required by standards are implemented in the integrated test sequences. Before performing the
test, the test object has to be classied in the Prole menu.
After repairs, modications and repeat testing, electrical appliances must also oer users protection
comparable with the protection of new appliances against electrical hazards. Tests in compliance with the
corresponding standards can determine whether the required safety is given. The tests outlined below
must be conducted in the specied sequence. Each test must be passed before the next test is started:
• Visual inspection
• Testing the protective earth conductor
• Measure the insulation resistance and leakage current or insulation resistance and an alternative
measurement in the substitute leakage current method for appliances with protection class I,
where this is permitted for the test object.
• Measure the insulation resistance, the touch current or insulation resistance and an alternative
measurement in the substitute leakage current method for appliances with protection class II and
for all touchable conductive parts of appliances with protection class I that are not connected to the
protective earth conductor, where this is permitted for the test object.
• Note for
Function tests:
The protective earth conductor resistance measurement must have been completed successfully before a
protective earth conductor current measurement is performed on appliances with protection class I!
An insulation resistance measurement at 500 V DC must be successfully completed before performing a
touch current measurement on appliances with protection class II or III (except IT equipment)!
External connection points from protective extra-low voltage generated in the device must be assessed for
compliance with the limits for the protective measure!
8.1 Specialist responsibility
There are particularly strict requirements for the specialist qualications of electricians.
DGUV Regulation 3 and the VDE Regulations, which are also formalised as electrical regulations,
include the legally binding and mandatory requirement that a responsible electrician is deployed.
Specialist responsibility includes the obligation to do the right thing. Accordingly, the corresponding
technical rules (electrical rules, VDE provisions etc.) must be observed. The specialist electrician must not
omit any actions that should have been taken to avoid damage. The specialist responsibility becomes
particularly clear when, for whichever reasons, tests cannot be performed completely. If a test required in
the corresponding standard cannot be performed for technical reasons or local factors, or the associated
workload, the specialist electrician must decide whether safety can be conrmed or not in spite of this
omission. This decision must be justied, documented and the specialist must take responsibility!

www.g-mw.de18
8.2 Electrical connection
According to the fundamental statutory regulations, the accident prevention regulations and valid
standards, it is not the manufacturer of the appliances to be connected who is responsible for the safety of
the on-site electrical connection and, where applicable, connection of the equipotential bonding system
to the device; these are the client’s responsibility. Tests on devices with xed connections cannot always
be conducted, often for technical reasons, local circumstances or the associated workload. If the appliance
connection is dicult to reach, full testing entails disconnecting its connections to the mains supply
(L1, L2, L3, N, PE) elsewhere, e.g. at the appliance’s mains terminal, socket, distributor etc., which is a
labour-intensive process.
WARNING!!!
Electrical appliances with a rated current of over 16 A must be connected directly to an all-pole mains
isolator (load switch, circuit breaker or power switch). Plugs and sockets or appliance connectors with a
rated current of over 16 A must not be connected or disconnected from the mains under load
(always deactivate beforehand).
Plugs and sockets or appliance connectors for appliances with a rated current of no more than 16 A do
not require a mains isolator.
8.3 Visual inspection
The appliances are always subject to a visual inspection for externally visible defects and, where possible,
for suitability for the place of installation:
• Damage to the housing
• External defects of the connecting cables
• Defects of the cord connector guard and strain relief of the connecting cables
• Signs of overload and improper use
• Unauthorised interference and modications
• Proper condition of the protective covers
• Soiling and corrosion with an adverse eect on safety
• Existence of necessary air lters
• Clear cooling vents
• Absence of leaks
• Clear legibility of safety-related inscriptions, e.g. warning symbols, protection class, fuse specications,
switch positions on circuit breakers, etc.
Note:
Externally visible defects, which could lead to a mechanical or re hazard, should be repaired immediately.
8.4 Individual measurement
Depending on the test object and potential electrical hazards arising from it, the following measurements
can be selected. Potential individual measurements are marked on the circuit in the appliance.

www.g-mw.de20
8.5 Function test
After completion of the electrical test, a function test must be carried out on the appliance.
A partial test can be sucient in accordance with legal requirements.
8.6 Inspecting the inscriptions
Safety-related inscriptions, for example stipulations on the direction of rotation, must be checked and,
where necessary, renewed or supplemented in suitable form.
8.7 Documenting the test
Tests must be documented when they are passed. If an appliance proves to be unsafe, this should be
clearly indicated on the appliance and the operator must be informed in writing (test report/list of defects).
The measurement values and any changes must be documented. Attachment of a test seal
e.g.„Tested per VDE 0701-0702 and DGUV Regulation 3“ on the appliance is recommended when a safety
test is passed.
