6.3. UL 508A SHORT CIRCUIT CURRENT RATING
When braking transistors are used with Underwriters Laboratories listed or recognized
drives, the short circuit current rating (SCCR) is determined by the SCCR rating of the
attached drive.
6.4. FUSE/CIRCUIT BREAKER SIZING AND RATING
Each module (except the 1600 Amp M14 chassis) comes equipped with its own
internal DC bus fuse. If the fuse happens to fail, it is not recommended to replace
the fuse and reapply power. Further damages could result. Consult Bonitron if
this situation arises.
If you wish to place fuses in your DC link, coordinate the fuse size with the proper wire
size used in your link as per local codes and regulations. Fast acting semiconductor
type fuses should be used.
