Testing and danger

All tests offered by the High Voltage or EMC generators are immunity tests on electronic equipment or devices.
These tests are potentially dangerous for the operator. Therefore, it is the responsibility of the user to avoid criti-
cal failures and risks to the environment and operator.
Long and distributed lines of the DUT can radiate certain energy to their vicinity. Therefore, it is also the respon-
sibility of the user to decide whether it can conduct immunity tests in a given installation.
Test voltages above 500V may generate spark discharges. Therefore, it is forbidden to test in an explosive envi-
ronment.
National and international recommendations regarding human safety must be followed.
People with certain health conditions, e.g. with a heart pace-maker or similar device, must be excluded from test-
ing.
When setting up the test national and international regulations regarding human safety must be guaranteed.
Generator and coupling/decoupling network must be grounded and connected to reference plane.

2.2.1. Coupling networks

The coupling network has mostly no On- Off switch and no internal fuse for the EUT power supply. This is
caused the different regulation in each country. The device under test must be protected by the user in an
adequate safe solution. As an option special adapters and switches can be built-in, but the user must to
specify these special solutions.
Generators and coupling devices must be grounded and connected to the reference ground.
For coupling pulses to the lines, the coupling path must be setted.
If a line has not to be coupled, it is necessary to disconnect or switch off this coupling path.
Special safety adapter cables are part of the delivery.

2.2.2. Danger from EUT

The device being tested may become defective and
ignite due to the influence of the applied test signal.
Therefore, the operator shall take the following precautions:
As soon as the EUT ceases to operate as intended, the test shall be stopped immediately.
In case of internal damage, the operator may be exposed to high frequency signals of high power (up to 75
Watts and more) anywhere on the EUT.
Cables and connectors can be overloaded by high voltages or energies.
Due to internal damage of components fire and/or explosion may occur.
Unintended use of the EUT may cause hazardous situations near the test area.
Never touch the EUT or anything connected to the EUT during a test.
It is suggested to read the operating manual carefully and completely. It is necessary to observe and
comply with all safety recommendations.
