5.1.2  Dc side switching

Switching occurs between rectifier and brake. KEB rectifiers and power boxes are pro

-

tected against the voltage peaks resulting from the switching.

• 

Not  permitted  for  drive  controller  operation,  since  the  power  box  or  the  rectifier 

would be destroyed..
