NOTICE
Device damage due to not removing the connection clip with a non-grounded line supply
When operating a converter FSH or FSJ on a non-grounded line supply (IT system), failure to
open the connection to the basic interference suppression module can cause significant
damage to the device.
● With a non-grounded line supply (IT system), open the connection to the basic interference
suppression module.
4.1.2
Minimum cross-section of the protective conductor
Overview
A high leakage current flows through the protective conductor in converter operation. The
protective conductor of the converter must not be interrupted for safe touch protection in
converter operation.
This primarily results in requirements for the minimum conductor cross-section of the protective
conductor.
No restriction applies to the length of the protective conductor for touch protection. However,
short protective conductors are advantageous for EMC-compliant installation.
