1.14 Test execution
The test area must be so organised that no unauthorised persons have access during execution of a test.
DUTs, together with their accessories and cables, are to be considered as being live during a test. The test
generator must be stopped and the DUT supply interrupted before any work is carried out on the DUT. This
can be implemented by pressing the “SYSTEM STOP” button.
DANGER!
The DUT is to be tested only in a protective cage or under a hood which provides
protection against electric shock and all manner of other dangers pertaining to
the particular DUT (see Dangers concerning the DUT).
CAUTION!
The safety instructions concerning all the instruments and associated equipment
involved in the test rig are to be observed.
CAUTION!
The configuration of the test rig is to be strictly in compliance with the methods
described in the relevant standard to ensure that the test is executed in a standard
conforming manner.
1.15 Dangers concerning the generator
DANGER!
Local burning, arcing, ignition of explosive gases.
DANGER!
Danger from the resultant DUT supply current caused by a flashover or breakdown
resulting from the superimposed high voltage effects.
DANGER!
Dangers from a disrupted DUT.
DANGER!
Disturbance of unrelated electronics, telecommunications, navigational systems
and heart pacemakers through unnoticed radiation of high frequency energy.
In most test rigs the interference voltage is superimposed on the protective earth conductor of the DUT in
accordance with the requirements of the test standard. Earth contacts or pins (e.g. in German and French
connectors) as well as the DUT earth can hence be at a dangerous to touch voltage. The screws, too, in certain
connectors are also linked to the protective earth conductor.
