Explosion hazard due to thick dust layers
This dust layers lead to heat insulation and thus increase the
temperature at the surface of the device.
• Regularly check and clean the equipment in areas en-
dangered by the risk of dust explosion.
• Prevent dust accumulations on the encoder by a suitable in-
stallation.
• Clean the encoder regularly according to the application.
