This input can be used to monitor the temperature of an externally connected brake resistor. If
the input between 104 and 106 opens, the frequency converter will trip on warning / alarm 27,
"Brake IGBT". If the connection is closed between 104 and 105, the frequency converter will trip
on warning / alarm 27, "Brake IGBT".
Normally closed: 104-106 (factory installed jumper)
Normally open: 104-105

Function
Brake resistor temperature switch.
If the temperature of the brake resistor gets too high and the thermal switch drops
out, the frequency converter will stop braking. The motor will start coasting.
A KLIXON switch must be installed that is `normally closed'. If this function is not
used, 106 and 104 must be short-circuited together.
Strip insulation of 9-10 mm
