4.3.3.8 Connecting load cells to an external supply
If the total resistance of the load cells is ≤75 Ω (e.g., more than 4load cells
with 350Ω), an external load cell supply is required. In this case, the internal
supply is replaced by a potential-free external supply.
The center of the external supply voltage (0 ext. supply) should be connected
to the device housing to ensure that the voltage reacts symmetrically to 0.
The internal supply is not connected.

The colors listed here apply for the MinebeaIntec products.
