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.

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.
