Safety instructions for installation

Injury and material damage caused by inappropriate fastening material
If screws of an incorrect property class have been selected or if they have been fastened to
an incorrect tightening torque, they may break or become loose. This will cause the machine
to move, which could damage the bearings. The rotor could smash into the machine enclosure
and machine parts could be flung out of place. This can result in death, serious injury or material
damage.
● Comply with the required property classes for screwed connections.
● Tighten the screwed connections to the specified tightening torques.
Injury and material damage caused by incorrect machine alignment
If the machine has not been properly aligned, this will mean the fastening parts are subjected
to stress/distortion. Screws may become loose or break, the machine will move, machine parts
could be flung out of place. This can result in death, serious injury or material damage.
● Carefully align the machine to the driven machine.
Material damage caused by improper handling
Mounting parts such as temperature sensors or speed sensors are attached to the machine
and could be ripped off or destroyed as a result of improper handling. This could lead to
machine malfunctions, extending even to total loss of the machine.
