with the DE shaft facing downwards, a protective canopy is recommended to cover the fan
cowling. This canopy is necessary to prevent the ingress of water and foreign objects that may
inhibit proper fan operation.
3.1.4 If the DE shaft is facing upwards, a protective canopy and / or suitable protective measures
are recommended to be taken to prevent liquids from entering the motor windings via the shaft.
3.1.5 Ensure cooling
For motors equipped with separately driven fan, please make design to ensure the motor
cannot be started when the fan is not running.
