WARNING! Fire Hazard. When using a braking unit, use a thermal relay on the braking resistors and configure a fault contact
output for the braking resistor unit to disconnect drive main power via an input contactor. Inadequate braking circuit protection
could result in death or serious injury by fire from overheating resistors.
