Information on the application of motors

7.1
Transport / storage before use
During transport and if the motors are out of operation for a long period of time, the cooling
circuit must be completely drained to protect against frost damage and corrosion.
The motors should be stored indoors in dry conditions with low-dust and low vibration levels
(v
eff
< 0.2 mm/s). 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.
Observe the additional notes regarding transport and storage in the operating instructions.
7.2
Environmental conditions
Operating temperature range: -15° C to +40° C (without any restrictions).
All of the catalog data refer to an ambient temperature of 40° C, mounted so that the motors
are not thermally insulated and an installation altitude up to 1000 m above sea level.
Under conditions other than those specified above (ambient temperature > 40°C or
installation altitude > 1000 m above sea level), the permissible torque/power must be
determined using the factors from the following table.
Ambient temperatures and installation altitudes are rounded-off to 5° C or 500 m
respectively.
