Material damage as a result of connection parts coming loose
If you use fixing elements made from the wrong material or apply the wrong tightening torque,
this could impair current transfer or cause connecting parts to become loose. This could result
in material damage to the machine or even in total failure, which could in turn lead indirectly to
material damage to the system.
• Tighten the screwed connections to the specified tightening torques.
• Observe any specifications regarding the materials from which fixing elements must be
made.
• Always carefully check the fastenings when carrying out service work.
