6. CONNECTION
- Protect the cable ends against contamination.
- No moisture must penetrate into the open cable end.
- Do not shorten the load cell cable. Connect the prepared cable end and roll up the
remaining cable.
- The cable screening should not be in contact with earth, except at the connecting
terminal in the measuring instrument.
- The load cell cabling should be kept away from power circuits.
The distance between the measuring cables and the power supply cables should be
at least 1m.
The load cell cables should be laid in separate cable conduits or steel pipes.
- Power supply cables should be crossed at right angles.

Extension cable
For connection from the cable junction box to the weighing electronics, we recommend
using standard extension cable PR 6135.
Do not use PVC cables for systems with AC supply!
With 4-core extension cables, the load cell supply and output voltage must be
connected to pairs of diagonally opposed cores of the extension cable. Resistance per
supply core < 1.25Ω.
