Dynamic Braking Option Overload Protection
To prevent overheating the dynamic braking option, set a sequence to de-energize the drive at the trip contacts of
the thermal overload relay.
Figure 3.52 Power Supply Interrupt for Overheat Protection Example
WARNING! 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.
