4.3 Validation
It is essential to demonstrate by validation that the requirements for intended special application are
met.
For validation, IEC 61800-5-2:2016 stipulates at least the following points in the project
documentation:
• Description of the application including an image
• Description of all safety-relevant components (including the software version) which are used in the
application
• List of the safety subfunctions which are used
• Results of all tests of these safety subfunctions
• List of all safety-relevant parameters and their values in the frequency inverter
• Checksums, date of inspection and confirmation by the inspection personnel
The configuration tests for NORDAC-PRO frequency inverters in identical applications may be
performed as a single type test for the identical application if it can be ensured that the safety
subfunctions in all devices are configured as intended.
The safety subfunctions of NORDAC PRO are maintenance-free. To rule out accidental re-
parameterisation after validation, the safety parameters must be re-checked after each suspension of
the safety password (P497). The validation, including documentation, must be repeated if the
configuration is changed.
