Note
Storage time up to two years
The storage time affects the properties of the roller bearing grease.
Store the motor for up to two years at -15° C to 55° C.
If you intend to place the motor in storage for longer than six months, you must ensure that
the storage area satisfies the following conditions.
Table 7- 1 Environmental conditions for long-term storage in the product packaging according to
Class 1K3 to EN 60721-3-1 - with the exception of influencing environmental variables
"Air temperature", "Highest relative humidity" and "Condensation"
Climatic ambient conditions
Highest relative humidity
< 60%, condensation not permissible
Mechanical ambient conditions
vibration-free storage room v
rms
Protection against chemical substances
Protected in acc. with Class 1C2
Biological ambient conditions
Suitable in acc. with Class 1B2
Six months for the conditions listed above.
Special preservation measures are
required for storage times of 6 months up
to maximum of two years.
Check the correct state of the motor every six months.
● Check the motor for any damage.
● Perform any necessary maintenance work.
● Check the state of the dehydrating agent and replace when necessary.
● Record the preservation work so that all preservation coating can be removed prior to the
commissioning.
The following ambient conditions encourage the formation of condensation:
● Large fluctuations of the ambient temperature
● Direct sunshine
● High air humidity during storage.
Avoid these ambient conditions.
Use a dehydrating agent in the packaging.
