Under normal ambient conditions, e.g. the stationary machine is not exposed to any external
vibration, no increased level of corrosion, ... then the following measures are required.
Longer non-operational periods
• For longer non-operational periods (> 1 month), either operate the machine or at least turn
the rotor regularly, approximately once per month.
• If attached, remove the rotor shipping brace before you turn the rotor.
• Carefully comply with the information in Section "Switching on" before switching on to
recommission the motor.
NOTICE
Restricted motor function
If not used for longer periods of time, material damage or complete motor failure can occur.
If the motor is out of service for a period of more than 12 months, then environmental eects
can damage the motor.
• Apply suitable corrosion protection, preservation, packaging and drying measures.
Switching on the anti-condensation heating, if available
Only switch on the anti-condensation heating after the motor has been switched o. Comply
with the data stamped on the plate of the anti-condensation heating, if available.
Taking the machine out of service
Detailed information on how to take the machine out of service is provided in Chapter Preparing
for use (Page33).
Lubricating before recommissioning
NOTICE
Dry running bearings
Bearings can be damaged if they do not have sucient grease.
• Re-grease the bearings if they have been out of service for more than one year. The shaft
must rotate so that the grease can be distributed in the bearings. Follow the instructions on
the lubricant plate.
• More information can be found in Chapter Rolling bearings (Page107).
