Connection

• Route the connection cable of the load cell such that any water condensate
that might occur, or any humidity, can drip away downwards. It must not
ingress into the load cell in any way. In the connection area of the cable
end, users must ensure that no humidity can ingress into the open cable.
• The cable must be routed such that damage to the external sheath by
chafing and/or own movements is prevented in daily operation.
• The load cells have been designed in four wire technology; a shortening
of the cable is not permissible.
• In order to maintain full precision, cable extensions should be carried out in
six wire technology.
• The cable is suitable for fixed routing, it may not be bent. The smallest
laying radius should not be less than 300 mm. Tensile straining and twisting
of the cable during and after fitting are not permissible.
WARNING
The cable union on the load cell must not be opened under any
circumstances; if this should occur by mistake, the load cell must be
returned to the manufacturer's works for repairs.
If elastomer bearings are used, the construction is insulated against the
foundations. Note in this connection, DIN/VDE 0100, Part 410, with regard to
a necessary potential compensation.
