The maximum wire length for PTC connection in ATV630 is shown as 300m for 1.5mm2 / AWG16 on the installation manual. Is it one way or two way ?

Maximum wire length


The maximum length must not exceed the sum of L1+L2 for 2-wires or L1+L2+L3 for 3-Wires.

L1 for example is distance between AIx and PTC, L2 is the distance between PTC and COM.
