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
applications on request.
Permissible minimum and maximum ambi-
ent temperature for operation
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 applica-
tions is only possible with special bearings for refrigeration applications on re-
quest. If special bearings for refrigeration applications are installed in the fan,
please observe the permissible maximum temperatures in the technical docu-
mentation 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 condensa-
tion does not occur.
Permissible temperature range for storage
and transport
-40...+80 °C
Permissible installation height 0...4000 m amsl
≤ 1000 m: no limitation
> 1000 m: max. permissible input current = current indication rating plate minus
5 % / 1000 m
> 2000 m: max. permissible line voltage = max. voltage indication rating plate
minus 1.29 % / 100 m
Permissible rel. humidity The motor is released for a relative humidity of 100 % at continental climate
without other ambient influences. Other ambient conditions on request.
Ball bearing life The bearing service life expectancy of the motor-integrated ball bearings deter-
mined according to the standard calculation procedure is largely determined by
the grease service life F10h and amounts to approx. 30,000-40,000 operating
hours. The fan or motor is maintenance-free due to the use of ball bearings with
“life-time lubrication.” After the grease service life F10h has been reached, bear-
ing replacement may be required. The bearing life expectancy can differ from the
stated value if operating conditions such as increased vibrations, increased
shocks, high or too low temperatures, humidity, dirt in the ball bearing or unfav-
ourable control modes are present. A service life calculation for special applica-
tions can be made on request.
Electromagnetic compatibility for the stand-
ard voltage 230 / 400 V according to IEC
60038
Interference emission EN 61000-6-3 (domestic household applications)
Interference immunity EN 61000-6-2 (industrial applications)
