User Manual of EM730/EM730E Series Inverter 3.2.8 Installation and wiring of braking resistor and braking unit Refer toChapter 10 for the selection and wiring of the braking resistor and braking unit. For the inverter with a built-in braking unit, connect the braking resistor between the inverter terminal (+) and PB terminal. For the inverter with no built-in braking unit, connect the terminals (+ and -) of the braking unit to those (+ and -) of the DC bus of the inverter, and the braking resistor to the PB+ and PB- terminals of the braking unit. Refer to the user manual of the BR100 braking unit for more information.
