Fuses and fuse bases
Each brake chopper module is connected to the DC bus of the drive system through fuses.
The table also shows a suitable fuse base.
A fuse with the same ratings from another manufacturer can be used if it meets the ratings,
and its melting curve does not exceed that of the fuse listed here.

Attenuator
The attenuator suppresses voltage spikes at the chopper input. The attenuator is otherwise
optional, but must be fitted if it is possible to disconnect all inverter units from the DC link
with the supply unit on.
