Connection of a temperature detection

3.2.4.1 Temperature detection terminals T1, T2
The KEB COMBIVERT G6 is delivered with a PTC evaluation. The function corresponds to
DIN EN 60947-8 and works in accordance with the following table:
Function of T1, T2
PTC or
temperature switch
The behaviour of the inverter in case of error/warning is defined with parameter
Pn.12. As standard the PTC input is deactivated. An instruction for the activation
can be found in the annex.
