Technical Data; Ratings - ABB ACS880-04 Hardware Manual

WARNING! If the drive is equipped with a brake chopper but the chopper is not
enabled by the parameter setting, the internal thermal protection of the drive
against resistor overheating is not in use. In this case, the brake resistor must be
disconnected.
Note: Some brake resistors are coated with oil film for protection. At the start-up, the
coating burns off and produces a little bit of smoke. Ensure proper ventilation at the start-
up.
