ABB AC500 V3 - Connection of active-type analog sensors (Current) with galvanically isolated power supply

Fig. 37: Connection example
CAUTION!
If GND is not directly connected to ZP at the sensor, the supply current flows
via the GND line to ZP. Measuring errors can only occur caused by voltage
differences higher than ±20 V DC between GND and ZP.
The measuring range can be configured Ä Chapter 1.6.2.2.3.6 “Parameterization” on page 472:
Voltage Common mode voltage 1 channel used
The function of the LEDs is described under Diagnosis and displays / displays Ä Chapter
1.6.2.2.3.7 “Diagnosis” on page 475.
In order to avoid error messages or long processing times, it is useful to configure unused
analog input channels as "unused".
