CONNECTING SEVERAL CELLS IN PARALLEL
: Connect several cells in parallel by using - if
necessary - a watertight junction box with terminal box. The cell connection extension cables must
be shielded, led individually into their piping or conduit and laid as far as possible from the power
cables (in case of 4-wire connections, use cables with 4x1 mm
2
minimum cross-section).
WELDING
: Avoid welding with the load cells already installed. If this cannot be avoided, place the
welder ground clamp close to the required welding point to prevent sending current through the load
cell body.
WINDY CONDITIONS - KNOCKS - VIBRATIONS
: The use of weigh modules is strongly
recommended for all load cells to compensate for misalignment of the support surfaces. The system
designer must ensure that the plant is protected against lateral shifting and tipping relating to:
shocks and vibration; windy conditions; seismic conditions in the installation setting; stability of the
support structure.
EARTHING THE WEIGHED STRUCTURE
: By means of a copper wire with suitable cross-section,
connect the cell upper support plate with the lower support plate, then connect all the lower plates to
a single earthing system. Electrostatic charges accumulated because of the product rubbing against
the pipes and the weighed container walls are discharged to the ground without going through or
damaging the load cells. Failure to implement a proper earthing system might not affect the
operation of the weighing system; this, however, does not rule out the possibility that the cells and
connected instrument may become damaged in the future. It is forbidden to ensure earthing system
continuity by using metal parts contained in the weighed structure.
