7.2.3 Overcurrent Protection by Means of Line Fuses or Circuit-Breakers
The cables for the drive line-up power supply must be protected against overcurrents. NH, D,
and DO-type fuses with a gL characteristic or suitable circuit-breakers can be used for this
purpose.
Note
For use in networks capable of supplying a maximum of 36 kA rms at 480 Vac if the device
is protected by means of the UL-approved (JFHR2) semiconductor safety fuse specified in
the manual.
The devices have to be protected with semiconductor fuses in accordance with the Manual.
The following tables list the requirements regarding line fuses and circuit-breakers for the
Active Line Modules and Smart Line Modules.
