ONNECTION
First the cable gland must be loosened. Then you have to feed the load cell cable through the cable gland
unless the shrink tube is fully disappeared in the box. The wires have to run below the printed circuit board
and will be pulled back to the top at the upper end of the printed circuit board. Afterwards you can connect the
cables to the screw terminals as indicated below.
For KPEX-6
