To prevent overheating the dynamic braking option, set a sequence to de-energize the drive at the trip contacts of the thermal overload relay.

Fire Hazard
When you use a braking unit, use a thermal relay on the braking resistors and set a fault contact output for the braking resistor unit to disconnect drive main power through an input contactor.
Incorrect braking circuit protection can cause the resistors to become too hot and cause serious injury or death.
