If the input between 104 and 106 is established, thefrequency converter will trip on warning / alarm 27, “Brake IGBT”. If the connection is closed between 104 and 105, the frequency converter will trip onwarning / alarm 27, “Brake IGBT”.Normally closed: 104-106 (factory installed jumper)Normally open: 104-105Terminal No. Function106, 104, 105 Brake resistor temperature switch.If the temperature of the brake resistor gets too highand the thermal switch drops out, the frequency con-verter will stop braking. The motor will start coasting.A KLIXON switch must be installed that is `normallyclosed'. If this function is not used, 106 and 104 mustbe short-circuited together.FC 300 Design Guide 8 Electrical InstallationMG.33.BC.02 - VLT® is a registered Danfoss trademark 1858
