Information on the application of motors
7.1
Transportation / storage before use
During transportation and if the motors are out of operation for a long period of time, the
cooling circuit must be completely emptied to protect against frost damage and corrosion.
The motors should be stored indoors in dry, low-dust and low-vibration (v
rooms. The motors should not be stored longer than two years at room temperature (+5 °C
to +40 °C) to retain the service life of the grease.
Read the additional notes regarding transportation and storage in the operating instructions.
7.2
Ambient conditions
Table 7-1
Operation
Storage/transport
Derating
If other conditions prevail (ambient temperature > 40° C or installation altitude > 1000 m
above sea level), the permissible torque/power must be defined using the factors from the
table (torque/power reduction according to EN 60034-6).
For ambient temperatures > 50°C, please contact your local Siemens office.
Ambient temperatures and installation altitudes are rounded off to 5° C or 500 m
respectively.
