9.2.7 Lubrication status of motor bearings (only 11-22 kW)

This display shows how many times the motor bearings have
been relubricated and when to replace the motor bearings.
When the motor bearings have been relubricated, confirm this
action in the INSTALLATION menu. See 9.3.8 Confirming
relubrication/replacement of motor bearings (only 11-22 kW).
When relubrication is confirmed, the figure in the above display
will be increased by one.

9.2.8 Time till relubrication of motor bearings (only 11-22 kW)
