It is recommended to use fuses when the braking module is connected to a DC link with more
than one inverter. Two fuses must be installed, one for the +UD and another for the -UD. The
current of each fuse must be 630 Arms with i
They must have an interruption capacity for direct voltage of 800 Vdc for the line 380...480 V,
1000 Vdc for the line 500...600 V and 1200 Vdc for the line 660...690 Vdc.
