Stoppages
The stoppage is a shutdown for a period of time, during which the motor is stopped but
remains at the location of use.
Under normal ambient conditions, e.g. the stationary motor not exposed to any vibration, no
increased level of corrosion, the following measures are required.
Longer non-operational periods
• For longer non-operational periods (> 1 month), either operate the motor 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
effects 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 off. Comply
with the data stamped on the plate of the anti-condensation heating, if available.
Taking the motor out of service
Detailed information on how to take the motor out of service is provided in Chapter
"Preparing for use (Page 25)".
