Above maximum surface temperatures are without any deposited dust on the motors. The possible
insulation effect of a dust layer on the surface has to be taken into account by the safety margin to the
minimum ignition temperature of the dust concerned. For up to 5 mm [1.97 in] layer thickness the safety
margin is 75 °C [167 °F]. For further information please see IEC 60079-14.
W
Warning
The above operating temperatures (ambient and oil) of the motor must be guaranteed by the end user.
W
Warning
It is compulsory to use oils whose inflammable degree is at least 50K above the maximum surface
temperature of the motor. See also
