DC link fuses
The Power Modules PM240-2 FSD and FSE do not have integrated overcurrent protection
for the DC link. You must therefore use aR characteristics fuses.

Description
The PM240-2 Power Modules cannot feed back regenerated energy into the line supply. For
regenerative operation, e.g. the braking of a rotating mass, a braking resistor must be
connected to convert the resulting energy into heat.
A thermostatic switch monitors the braking resistor for overtemperature and issues a signal
on an isolated contact if the limit value is exceeded.
