1.16 Dangers concerning the DUT
DUTs are often simply functional samples that have not previously been subjected to any safety tests. It can
therefore happen that in some cases that the DUT is quickly damaged by internal overloads caused by the
control electronics being disrupted or it may even start to burn.
DANGER!
Internal disruption of the electronics can result in the interference voltage or the
DUT supply voltage being present on the DUT‘s housing.
CAUTION!
As soon as the DUT shows signs of being disrupted the test must be stopped and
the power to the DUT switched off.
CAUTION!
Electrical breakdown or arcing from and in plugged connections that are over-
stressed voltage-wise during the test.
DANGER!
Explosion of electronic components with fire or fragmentation as a result of the
energy dissipated, e.g. from the resultant supply current or ignition of vaporised
plastics materials.
CAUTION!
Faulty behaviour by the DUT, e.g. robot device strikes out, temperature controller
fails, etc.
