Electrical connection

C16i
Position the load cell cable so that any condensation wa­
ter 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 abra­
sion because of the load cell's propermotion.
Electrical and magnetic fields often are the cause for the
introduction of disturbing voltages into the measuring cir­
cuit.
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. damage 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
