Signal cable

The junction box is connected to the weighing module by means of a signal cable. Use a

shielded cable with six cores as the signal cable. We recommend the SIWAREX cable

Li2Y2x0.75St+2x(2x0.34St)-CY:

● For standard applications: 7MH4702-8AG, orange sheath color.

● For intrinsically safe Ex applications: 7MH4702-8AF, light blue sheath color.

The cables and lines must correspond to the installation regulations according to EN 60079-

14. In hazardous areas, the diameter of individual conductors must not be smaller than 0.1

mm.

Short circuit/explosion hazard

At an ambient temperature T ≥ 60 °C, use heat-resistant cables which are approved for an

ambient temperature at least 20 K higher.

Note

The maximum cable length between the load cell and the weighing module is stated in the

weighing module documentation.
