ABB AC500 V3 - Connection of active-type analog sensors (Voltage) with no galvanically isolated power supply to the analog inputs

The following measuring ranges can be configured Ä Chapter 1.7.5.2.7 “Parameterization”
on page 815 Ä Chapter 1.7.5.2.9.1 “Input ranges voltage, current and digital input”
on page 828:
Current 0 mA...20 mA 1 channel used
Current 4 mA...20 mA 1 channel used
The function of the LEDs is described under Diagnosis and displays / Displays Ä Chapter
1.7.5.2.8 “Diagnosis and state LEDs” on page 821.
Unused input channels can be left open-circuited, because they are of low resistance.
To avoid error messages through unused analog input channels in measuring range 4 mA...20
mA, these channels should be configured as "Not used".
Connection of active-type analog sensors (Voltage) with no galvanically isolated power supply to the
analog inputs
The following figure shows the connection of active-type analog sensors (voltage) with no
galvanically isolated power supply to the analog input AI0. Proceed with the analog inputs AI1 to
AI3 in the same way.
