No jumper required, when
a sensor is not connected
Temperature sensor (PTC )
1650...4k tripping resistance
750...1650 reset resistance
use with wiring diagram 2
use with wiring diagram 1
Don't install sensor wires with control wires!
Must use double shield when running these
wires with motor wires!
It is necessary to activate this function via
software parameter! See US.33

Braking resistor
with line side over
temperature cutoff
This is the only way to turn
off voltage to the resistor in
the event of failure of the
internal braking transistor of
the inverter.
24VDC or 120VAC contactor control voltage
Note: a NC thermal switch not PTC device on the resistor is required.
