Safe Torque Off (X4); Control Cable Connection Procedure R0 - ABB ACS560 Hardware Manual

One, two or three Pt100 sensors for motor temperature measurement can be
connected between an analog input and output as shown below. Do not connect both
ends of the cable shields directly to ground, nor connect the capacitor at one end to
