Flat-design resistors with FKB11B / FKB12B / FKB13B and FHS11B / FHS12B / FHS13B
Proceed as follows to install flat-type braking resistors:
• FKB11B / FKB12B / FKB13B: Installation on the back panel of the control cabinet:
• FHS11B / FHS12B / FHS13B: Installation with mounting rail

4.4.1
Braking resistor connection
• Shorten the cables to the required length.
• Use 2 tightly twisted leads or a 2-core shielded power cable. Cable cross section ac-
cording to trip current I
F
of F16.
• Protect the braking resistor with a bimetallic relay (F16, see wiring diagram) with trip
class 10 or 10A. Set the trip current according to the technical data of the braking
resistor.
• For braking resistors in the BW..-T series, you can connect the integrated thermostat
using a 2-core, shielded cable as an alternative to a bimetallic relay.
• The flat-type braking resistors have internal thermal overload protection (fuse cannot
be replaced). Install the flat-type braking resistors together with the appropriate touch
guard.
