Electrical con nections
The power supply has to be connected to and . is considered as
system ground. If the analogue output is connected to a controller the same ground
reference has to be used for the CF8-W-Disp-GH unit and for the control system!
Unless different transformers are used, special precautions need to be taken.
PLEASE NOTE! The CF8-W-Disp-GH
signal ground is not galvanically
separated from the CF8-W-Disp-GH
power supply!
NOTE!
The same ground reference has
to be used for the CF8-W-Disp-GH
unit and for the control system!
Connect the power after mounting. The
analogue output should be connected before
measuring.
