Data obtained at optimum efficiency level. The efficiency values displayed for achieving
conformity with the Ecodesign Regulation EU 327/2011 has been reached with defined air
duct components (e.g. inlet rings). The dimensions must be requested from ebm-papst. If
other air conduction geometries are used on the installation side, the ebm-papst evaluation
loses its validity/the conformity must be confirmed again. The product does not fall within
the scope of Regulation (EU) 2019/1781 due to the exception specified in Article 2 (2a)
(motors completely integrated into a product).

Protection class
assignment
III; Requires supply with safety extra-
low voltage SELV.
This component for installation may
have several local protection classes.
This information relates to this
component’s basic design.
The final protection class is based on
the component’s intended installation and
connection. If there is a PE connection
point on the housing, it must not be
visible after installation.
