Installation and Operating Instructions
2 .5 Performance data
The motor type plate gives an indication of the mandatory electrical values. These must be coordinated with the local
supply network. The fan performances* were established on a test stand according to DIN EN ISO 5801: 2010-12; they
apply to the nominal speed and standard design without protection grille with unhindered inflow and outflow and an
intake and pressure-side pipe section with length 2.5 x length duct side. Different versions and unfavourable installation
and operating conditions can lead to a reduction of output.
2 .6 Noise data
The noise data* also refers to the aforementioned directive. Casing variations, unfavourable operating conditions and
many other things can lead to an increase in the specified catalogue values. Data that refers to certain distances (1, 2,
4 m) apply to free field conditions. With regard to installation, the sound pressure level can differ significantly from the
catalogue data, as it is highly dependent on the installation conditions, i.e. on the absorption capability of the room, the
room size among other factors.
3 .0 Technical data
The technical data can be found on the type plate or on HeliosSelect at heliosselect.de.
