3.1.4 Motor position – special features IM V3, IM V6
If the end of the shaft faces upwards, e.g. version IM V3, IM V6, a cover must be provided by the
operator / installer, which prevents foreign bodies from falling into the fan cover of the motor (see
EN IEC 60079-0:2018). This must not obstruct the fan from cooling the motor. If the end of the shaft
faces downwards (AS, inclination 20° to 90°), e.g. versions IM V1, IM V5, the motors are to be used with
a protective cover on the fan cover. For an inclination of less than 20°, an appropriate protective device,
which meets the above mentioned conditions, must be provided by the operator / installer.
A hand wheel on the second shaft end is not permitted.
