2. Select the resistance value, power and brake usage (ED %) according to Delta rules.
For safety, install a thermal overload relay (O.L) between the brake unit and the brake resistor in
conjunction with the magnetic contactor (MC) before the drive for additional protection. The thermal
overload relay protects the brake resistor from damage due to frequent or continuous braking. Under such
circumstances, turn off the power to prevent damage to the brake resistor, brake unit and drive.
