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

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.

Attach any missing warning labels to the components, where necessary in the
national language.
