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.
