2.2 Device design
2.2.1 SK 140E-1-O
The SK 140E-1-O (Mat. No. 275101400) is a motor starter without permanently integrated rectifier. However, it
is possible to install any rectifier by Getriebebau NORD. This can be utilized in case of retrofitting or at system
voltages of < 380 V. Spacer bolts are used for the assembly of the rectifiers. (Æ See also chapter 5.1 )
2.2.2 SK 140E-1-BSG2
The design with integrated fast acting brake rectifier has the designation SK 140E-1-BSG2 (Mat. No.
275101405). With this device design, a fast acting brake rectifier has been added to the basic function to
directly control a brake mounted to the motor. Consequently, the brake voltage supplied equals supply voltage
x 0.45. The jumper [L] can be used to affect a gradual switch-off by shorting the integrated DC switch. (Æ See
also chapter 5.1 )
