Figure 2-6. Installation Dimensions
Connect the cables to terminals according cable diagrams in Appendix (B, C, D, E, F or G)
depending on installed load cell type.
Do not connect solid conductors to terminals. Do not crimp pins to stranded
cores.
Earthing
The metal bottom of PFEA111-20 and PFEA112-20 connects to the metallic DIN-rail which
serves as the Tension Electronics earth connector.
This is to ensure a good earth connection both for internal logic and for the EMI immunity
and RF emission of the electronics.
The DIN-rail must have a good connection to the PE (Protective Earth) of the cabinet.
To achieve the best possible corrosion resistance, DIN-rails should be chromium plated, for
instance, yellow chromium treated. Use star washers with each screw used to fasten the
DIN-rail to the mounting plate.
To fasten the DIN-rail onto the mounting plate, the minimum screw diameter is 5 mm and
the maximum distance between screws is 100 mm.
