1.4.
Failures and Over stressing
- If it is assumed that a safe operating mode of the equipment is no longer possible, the mains connection must be re-
moved and the equipment secured from unintentional use.
- An unsafe operating mode is characterized as follows:
- the equipment shows recognizable damages;
- the equipment is not working;
- the equipment has experienced severe transportation stress;
- the equipment has been stored in an unsuitable environment for some time.
Please exercise prudence in determining whether a device is unsafe or not.
1.5.
Danger during testing
ESD tests 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 critical failures and risks to the environment and operator.
Long and distributed lines to the EUT are able to radiate a certain energy to their vicinity. Therefore it is also the responsibil-
ity of the user to decide whether it is allowed to conduct immunity tests in a given installation.
Test voltages above 500V may generate spark discharges. Therefore it is forbidden to test in an explosive environment.
National and international recommendations regarding human safety must be followed.
People with certain health conditions, e.g. with a heart pacemaker or similar device, should be excluded from testing.
- When setting up the test, national and international regulations regarding human safety have to be guaranteed.
Handicapped people, e.g. persons using peacemakers, are not
allowed to use this test instrumentation. Hazardous
radiation may influence these products.
1.5.1.
Power Mains Supply and Ground Reference.
 EMC and High Voltage test setups must have a good decoupled and stable power mains supply.
 Decoupling may be achieved by:
- Filtering
- The use of isolation transformers
 By the use of isolation transformers, ground current detectors will not work as intended anymore.
 EMC and High voltage test areas must include a clear ground reference strategy. All generators, CDN’s and LISN’s
must be connected directly and as short as possible to the ground reference.
 The ground reference system must be connected to the Protective Earth (PE) connection of the laboratory.
