(1)   All parameters conform to the specified class except for the ambient temperature which is limited by other components of the system.

(2)   Power reduction with motors at ambient temperatures exceeding +40 °C (104 °F). For more information, contact your local Schneider Electric service representative.

(3)   All parameters conform to the specified class except for the relative humidity which is limited by other components of the system.

(4)   Higher temperatures can cause damage to the superficial structure. Lower temperatures increase the stiffness and reduce the service life of the toothed belt.

(5)   Storing the toothed belt at a relative humidity of maximum 50% helps to avoid a reduced service life of the toothed belt.

Ambient conditions apply with motor and gearbox. For further information, refer to the corresponding motor or gearbox manual.

For further information about storage conditions, refer to Transport and Storage.

Information About Increased Corrosion Resistance

Increased corrosion resistance does not imply corrosion resistance under any ambient condition. For further information, refer to Incompatible Environments.

NOTE: Coated materials loose their increased corrosion resistance if the coating is damaged or worn.
