Environmental Conditions - Siemens SIMOTICS S-1FG1 Operating Instructions Manual

2.2.3

Environmental conditions

You can classify the ambient conditions for stationary use at weatherprotected locations
according to the standard DIN IEC 60721-3-3. The environmental effects and their limit
values are defined in various classes in this standard.
You can assign the SIMOTICS S-1FG1 servo geared motors to climate class 3K4 with the
exception of the environmental factor "condensation". Condensation is not permissible.
The following temperature ranges apply for natural-cooled and forced-ventilation motors.
