CAUTION
Condensation water
During motor operation, humid air can condense inside the machine. Depending on the
environmental and operating conditions, therefore, remove the condensation water plug to
drain the water. Re-install the condensation water plug. [ID 1151.00]
5.2 Stoppages
Prolonged outage periods
Operate the motor at least once monthly in the event of downtimes lasting more than 1
month. If the motor is not to be used for a period in excess of 12 months, you must take
suitable anti-corrosion, mothballing, packaging and drying measures.
Switching on the anti-condensation heating
If anti-condensation heating is available, it can only be switched on 1 hour after the motor
has been shut down. This prevents damage to the winding insulation and the formation of
condensation water. [ID 839.01]
