Basic safety instructions
Load cells are precision components and must therefore be handled carefully. Particular
care must be taken during transport and installation.
Danger to life from falling loads
• Load cells are not machine components which have been constructed with the normal
safety factors. For this reason, appropriate protection against falling and catastrophes
must be implemented in accordance with the potential risks.
• Use suitable hoisting equipment to lift the load carrier. Observe the appropriate safety
regulations.
Damage to load cells through incorrect handling
• SIWAREX load cells are only permitted to be mounted and connected by qualified
personnel.
• Mechanical shocks or falls can irreparably damage the load cell.
• When mounting the load cell, ensure that you do not damage or cut the cables of the
load cell. Load cells must not be carried by their connecting cables.
• Protect the load cells from shocks and welding currents. Replace the load cells with
dummies until the installation work on the scale structure is completed.
Damage to load cells through high currents
• If welding is undertaken after the load cells have been installed, ensure that the welding
current is not diverted through the load cells.
– You can do this by attaching the grounding clamp of the welding unit making reliable
contact close to the weld.
– Bridge the load cells with a ground cable, for more on this, see Accessories
(Page 98)
– Disconnect the individual load cells.
• Undesirable electrical currents can arise during lightning. Bridge the load cells with a
highly flexible ground cable to protect the load cells against such currents, for more on
this, see Accessories (Page 98).
