4.1 Installation of a power emergency off switch
The CDN itself has an internal power switch to control EUT power ON/OFF, accessible via
the user interface or the software, but nerveless, it is recommended to connect the EUT
power through a properly rated circuit breaker and an emergency off button as per IEC/EN
61010-1. In order to ensure an easy and quick access, the button should be located close to
the test setup and should be clearly and visibly labelled as a device for
“Emergency power
ON/OFF
” switching.
WARNING - The test setup should only be accessible to trained persons.
Dimensioning of the mains supply and rating of fuse protection of the AC power supply must
conform with local electrical codes and EUT requirements.
Inappropriate arrangement, mounting, cabling or handling of the device under test or the
protective elements can make the protective features that are incorporated in the design of
the instrument worthless.
