NOTICE
Property damage due to loose power connections
Insufficient tightening torques or vibration can result in loose power connections. This can
result in damage due to fire, device defects or malfunctions.
•
Tighten all power connections to the prescribed torque.
•
Check all power connections at regular intervals, particularly after equipment has been
transported.
NOTICE
Damage to equipment due to unsuitable tightening tools.
Unsuitable tightening tools or fastening methods can damage the screws of the equipment.
•
Be sure to only use screwdrivers which exactly match the heads of the screws.
•
Tighten the screws with the torque specified in the technical documentation.
•
Use a torque wrench or a mechanical precision nut runner with a dynamic torque sensor
and speed limitation system.
WARNING
Unexpected movement of machines caused by radio devices or mobile phones
Using radio devices or mobile telephones in the immediate vicinity of the components can
result in equipment malfunction. Malfunctions may impair the functional safety of machines
and can therefore put people in danger or lead to property damage.
•
Therefore, if you move closer than 20 cm to the components, be sure to switch off radio
devices or mobile telephones.
•
Use the "SIEMENS Industry Online Support app" only on equipment that has already been
switched off.
WARNING
Unrecognized dangers due to missing or illegible warning labels
Dangers might not be recognized if warning labels are missing or illegible. Unrecognized
dangers may cause accidents resulting in serious injury or death.
•
Check that the warning labels are complete based on the documentation.
•
Attach any missing warning labels to the components, where necessary in the national
language.
•
Replace illegible warning labels.
