♦
It is recommended that fuses be used for multi-motor systems using
a common DC bus (incoming power >> braking unit rating).
♦
High voltage fuses (1000 V) must be used in the positive and
negative branches (fuse type see Table 7-1).
♦
Fuses are not required for single-motor drives (one inverter for each
braking unit).
These fuses only provide protection in critical situations. They do not
protect the braking unit or external brake resistor.
