5 Electrical connection
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 propermotion.
Electrical and magnetic fields often are the cause for the introduction of dis­
turbing voltages into the measuring circuit.
The optional cable with an outer braided wire covering for the C16i with option
20R, is intended for use when there is increased mechanical stress (e.g. dam­
age caused by gnawing rodents). If this cable is used, the outer braided wire
has to be connected to potential equalization at least once, to avoid accidental
energization. This outer braided wire is not used to shield the load cell. The
inner braid of the load cell cable is used for shielding.
Therefore:
S Use shielded low‐capacitance cable only (HBM cables meet these
requirements)
S 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
S Avoid the stray fields resulting from transformers, motors and contactors
