WARNING - The test area must be organized so that
unauthorized persons do not have access during the
execution of a test. If a safety contact (Interlock) is used
as a means of access control to the test zone (e.g. a
Faraday cage), then an additional contact connected in
series is necessary to provide protection for parts of
the EUT that are likely to be touched accidentally.
During a test, the EUT together with its accessories and
cables are to be considered live at all times. The test
system must be stopped and the EUT supply disconnected
before any work can be carried out on the EUT. This can
be achieved simply by opening the interlock circuit.
The EUT 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 EUT (see: User warnings - Generator).
The user must observe safety instruction for all the
instruments and associated equipment involved in the
test setup.
Test setup configuration is to be strictly in compliance
with the methods described in the relevant standard to
ensure that the test is executed in a compliant manner.
system itself does not produce any excessive radiation; however, the injection
of interference pulses into the EUT can result in the device and/or its associated
cables radiating EMI. To avoid radiating unwanted interference the standards
organzations recommend that the test setup be located in a Faraday cage.
Since the purpose of the test system is to produce interference signals for
interference immunity testing, the requirements in the IEC/EN 61000 series
concerning limiting the radiated EMI can only be complied with by operating
the test system inside a Faraday cage.
