Correct wiring of Power GND and Signal GND for IC Advanced and
Proportional
When using the feedback output, it is important to use the right connection setup. Attention should be paid to
the two ground connections. Power GND in the Power connector and Signal GND in the Control connector. When
using either 0-10V, Hall or PWM feedback, the Signal GND must be used. For optimal accuracy, the Signal GND
is connected to the Power GND as close as possible to the feedback input equipment.

The following connection illustration applies only for 4-20mA:
* Only to be used on differential input card. Do not use single ended input card.
Do NOT connect or put the white wire anywhere near GND, as this will create ground loops, disturbing
the mA-signal.
