Temperature sensor KTY84–1C130/PTC
3 EP +24 V (enable pulses)
4 EP M (enable pulses)
Voltage: 24 V DC
Current consumption: 10 mA
Isolated input
Signal propagation times:
L → H: 100 μs
H → L: 1000 μs

2
Type: Screw terminal 1 (see Connection System)
NOTICE
The KTY temperature sensor must be connected with the correct polarity.
WARNING
For operation, 24 V DC must be connected to terminal 3 and ground to terminal 4. Upon
removal, pulse suppression is activated. Feedback is deactivated and the bypass relay
drops out. If the Line Module is not disconnected from the line supply when the EP terminal
is deactivated (e.g. a main contactor is not installed), the DC link remains charged.
NOTICE
If a drive line-up is switched off by means of the line disconnecting device, the voltage at
terminals 3 (EP +24 V) and 4 (EP M) must be interrupted beforehand. This can be carried
out using a leading breaking auxiliary contact (≥ 10 ms), for example.
This protects external loads located parallel to the drive on the same switching component.
