BFS5-T Type AL brakes 

The AL brake is a special MEW Lifter brake used to control speed (AL control) by connecting a MEW Lifter to the secondary side of a wound-rotor induction motor. When the AL brake is to be used, place a brake for stopping on the coupling side of the motor, and the AL brake on the anti-coupling side

Note 19: See Table  1 (P.1  and 2) for major ratings.

Note 20: Shared  use for 200 V and 400 V is possible by changing the connection of the MEW Lifter, but shared  use for 50- and 60-Hz  frequencies is not allowed.
