4.1 Safety instructions
NOTICE
Incorrect assembly of the load cell
Damaging of load cells, installation parts or load bearing implement
With load cells of smaller rated loads, there is a risk of stretching the load cell bodies when
attaching force transfer devices, e.g. when tightening locknuts.
Torsional and bending moments, eccentric loads and transverse loads are disturbance
variables. These disturbances cause errors in the measuring result and can damage load cells
and elastomer bearings if the maximum limits are exceeded.
● To ensure safe use of the hoisting gear, provide indented claws or crane eyebolts on the
● Do not overload the load cells.
● Put the load bearing implement down slowly.
● Use overload protection that securely absorbs the desired loads. The overload protection
● Introduce the load in the measuring direction of the load cell.
● The mounting components normally allow so much room for movement that heat
NOTICE
Incorrect welding
Incorrect welding can damage the load cell.
● Do not conduct the welding current over the load cells.
NOTICE
Missing grounding of the load cell
Undesirable electrical currents can arise during lightning and damage the load cell.
● Bridge the load cells with highly flexible grounding cables. See the section Grounding cable

expansion will not result in lateral loading.
– Attach the grounding clamp of the welding unit making reliable contact close to the weld.
– Bridge the load cells with a highly flexible grounding cable. See the section Grounding
cable (Page 17).
– Disconnect the individual load cells.
