Changes to the speed to adjust process variables
(controlled operation) should be max. 16.7 rev/sec
(1.75 rad/sec), except when running through reso-
nance frequencies.
The fans’ service life can be increased by quickly
running through resonance frequencies.
The operating manuals from the control unit manu-
facturer must be observed.
The EMC Directive 2014/30/EU must be complied
with.
General notes
The motor and transformer must be positioned as
close to one another as possible
Cables must be sheathed and shielded
Cables, cable ends, the frequency inverter and the
motor must be earthed.
It is advisable to use all-pole sine filters.
3.6.3 Smoke extract
During smoke extract operation, the fans only extract
smoke gases in the event of a fire to remove the smoke
from the fire compartments.
