Duty type of motor/fan
Continuous operation with occasional starts (S1) according to DIN EN 60034-1:2011-
02.
Occasional starting between -35
°
C and -25
°
C is permissible.
Continuous operation below -25
°
C only with special bearings for refrigeration applica-
tions on request.
Permissible minimal and maximal am-
bient temperature for operation
For a version with plastic wall plate (design Q): -10...+40
°
C
Please refer to the technical documentation of the product for the minimum and
maximum ambient temperature valid for the respective fan.
Operation below -25
°
C as well as partial load operation for refrigeration applications is
only possible with special bearings for refrigeration applications on request. If special
bearings for refrigeration applications are installed in the fan, please observe the
permissible maximum temperatures in the technical documentation of the product.
To avoid condensation the drive must be continuously energized due to the application
of heat, with interruptions such that cooling to the point of condensation does not occur.
Permissible temperature range for
storage and transport
