Temperature sensor (PTC )
1650Ω...4kΩ tripping resistance
750Ω...1650Ω reset resistance
On F5 B/G units it is necessary to activate the function through
parameter CP.28.

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.
