( Stop!
825X and 935X brake units must only be operated together with
Lenze brake resistors! Otherwise the brake units can be
damaged!

) Note!
With 400 V mains systems it is also possible to use a regenerative
power supply unit 934X instead of a brake unit. Advantage: No
heat generation in generator mode.
