(1) Installation altitude without power reduction < 1000 m (3281 ft).

(2) Power reduction for Lexium P Compact versions with ILM motors at ambient temperatures exceeding +25 °C (+77 °F). Power reduction depends on the application. If some severities of parameters deviate from the specified ambient conditions, contact your local Schneider Electric service representative for more information.

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

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