3.1.6 Load Cell Connection
The cable colors shown in this chapter are applicable to the Sartorius PR 62XX series load cells.
Before connecting other types, carefully follow the information related to the assignment of
load cell/platform cable colors.
• The distance between the measuring cables and the power cables should be at least 1 m.
• The measuring cables should be laid in separate cable conduits or steel pipes connected to earth potential.
• Power cables should be crossed at right angles.
Load cell supply circuit
The load cell supply voltage is fixed to 12 V DC and protected against short circuit.
Load resistance of load cells
≥75 ¥, e.g. 8 load cells of 650 ¥ each.
