The motors intended to use in hazardous area are not allowed to be over-loaded without verified firm control of the over-load and its time. The maximum operating settings are stated in the motor rating plate and/or in its certificate. The motor stall protection shall be based on the maximum safe stall time stated in the motor datasheet, and in case of increased safety (Ex e) machine on te time stated in the motor rating plate and its certificate.
