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.
