5.6 Installing the machine
5.6.3
Removing the rotor shipping brace
If a rotor shipping brace is attached to the machine, remove it at the last possible moment,
for example, when you are ready to push on the output or drive element.
Storing the rotor locking device
Store the rotor locking device in a safe place. It must be remounted if the machine is removed
and shipped on further.
Details relating to the alignment accuracy are provided in Section "Technical Data".
5.6.4
Recommended alignment accuracy
The alignment accuracy required depends essentially on the configuration of the overall
machine train. Observe the required alignment accuracy of the coupling manufacturer in all
cases when aligning the machine.

5.6.5
Mounting the drive output elements
The rotor is dynamically balanced. For shaft extensions with feather keys, the type of balancing
is specified using the following coding on the face of the drive end of the shaft extension and on
the rating plate:
• "H" means balancing with a half feather key (standard)
• "F" means balancing with a whole feather key
• "N" means balancing without a featherkey.
