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.

* 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.
