3.5.4 Connecting Load Cells with External Supply
When the load of the load cells is < 75 ohms (e.g. more than 4 load cells with 350 ohms), external
load cell supply is required. In this case, the internal supply is replaced by a potential-free external
supply. The neutral wire of the external supply voltage (0 ext. supply) must be connected to the
instrument housing to ensure that the voltage is symmetrical to 0. The internal supply is not
connected.
The cable colors indicated
above are valid for connecting
cable PR 6135.
When using other load
cells/cables, the assignment of
colors may differ.
For this reason, the relevant
manual or data sheet should be
consulted for assignments of cable
colors before connecting.
