Implementing a motor temperature sensor connection

WARNING! IEC 60664 requires double or reinforced insulation between
live parts and the surface of accessible parts of electrical equipment
which are either non-conductive or conductive but not connected to the
protective earth.
To connect a motor temperature sensor and other similar components to the drive,
you have four alternatives:
1
230 V AC
2
230 V AC
+ 24 V DC
