Braking Resistors
The braking resistors can be subject to unforeseen overloads due to possible failures.
The resistors have to be protected using thermal protection devices. Such devices do not have to interrupt
the circuit where the resistor is inserted but their auxiliary contact must interrupt the power supply of the drive
Warning
power section. In case the resistor foresees the precence of a protection contact, such contact has to be
used together with the one belonging to the thermal protection device.
