Synchronous Servomotors MSK For Potentially Explosive Areas
Climatic environmental conditionsare defined according to different classes
as specified in DIN EN 60721-3-3, Table 1. The conditions are based on ob‐
servations made over long periods of time worldwide and take into account
all influencing variables, such as the air temperature and humidity.
On the basis of this table, Rexroth recommends Class 3K4 for permanent
use of the motors.
The following table provides extracts from this class.
