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.
