Position the load cell cable so that any condensation water or moisture forming on the cable can drip
off. It must not be routed to the load cell. In addition, make sure that no dampness can penetrate the
open end of the cable.
Furthermore, the cable must be placed such that the cable sheath suffers no damage, e.g. from
potential abrasion because of the load cell's proper motion. A fitting (Ø 10) at the load cell cable entry
enables a protective cable conduit with nominal diameter 10mm to be mounted.
Electrical and magnetic fields often are the cause for the introduction of disturbing voltages into the
measuring circuit.
Therefore:
D Use shielded low-capacitance cable only (HBM cables meet these requirements).
D Do not lay the measuring cables in parallel to power cables, especially high-tension and control
lines. If this is not pssible, use steel conduits, for example, to protect and shield the measuring
cables.
D Avoid the stray fields resulting from transformers, motors and contactors.
3.1
The bus wiring of several load cells come into being by joining together the connection cables' core
ends with identical colours. HBM recommend the use of a junction box without dropping resistors
(e.g. VKK2--6).
