WARNING
Incorrect 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.
NOTICE
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.
● Where necessary, use suitable steps when performing installation work on the machine.
● Do not stand on cables or attachments during installation. Do not use attachments as
steps.
5.3.1 Selecting fixing screws
● Unless specified otherwise, use mounting bolts with at least strength class 8.8 to ISO 898‑1.
In this way you guarantee that the machine is securely mounted and the forces can be
transferred through the torque.
● Take into account the maximum forces occurring in the case of a fault such as short circuit
or system transfers in phase opposition.
– When selecting the bolts
– When designing the foundation

Preconditions for smooth, vibration-free operation:
● Stable foundation design
● Precise alignment of the machine
● Correct balancing of parts to be fitted to the shaft end.
● Maintaining the vibration velocity according to ISO 10816‑3
