conveyed by the fan. For the protection
of persons, the protective grilles are an
important safety element. They prevent
interference with the inside of the fan.
However, during maintenance and re-
pair work, the impeller must be accessi-
ble to detect and repair damage to the
fan. For this work, the protective grilles
must be able to be dismantled.
To avoid dangerous situations and inju-
ries, it is therefore necessary to check
regularly during maintenance and repair
whether all protective grilles are present
and installed. Missing protective grilles
must be replaced immediately.
The fan is equipped as standard with a
protective grille on the inlet. The protec-
tive grille on the pressure side is op-
tional accessory. If the pressure side is
accessible and is not connected to any
line, a protective grille must also be in-
stalled here.
Danger from exceeding the maximum
switching cycles
WARNING!
Risk of injury due to com-
ponent failure
Exceeding the maximum per-
missible speed can lead to
breakage of the impeller.
Fragments are thrown out of
the fan and can injure by-
standers.
Observe the switching
cycles specified in chap-
ter "2.4 Appropriate
The impeller of the fan is designed for
high loads. Nevertheless, it can be
damaged by repeated, impermissible,
rapid starting and braking. This breaks
the impeller and parts of it are thrown
out of the discharge side. People hit with
fragments suffer serious injuries. Adhere
to the maximum number of switching
operations (see chapter 2.4) per hour
and the information on maintenance and
repair.
Danger from rotational speed
WARNING!
Risk of injury due to com-
ponent failure
Exceeding the maximum per-
missible rotational speed can
lead to breakage of the im-
peller. Fragments are thrown
out of the fan and can injure
bystanders.
Keep the maximum
number of rotational
speed or maximum fre-
quency indicated on the
name plate
The impeller of the fan is designed for
high loads and rotational speeds. If the
maximum permissible rotational speeds
are exceeded, the material can give way
and break. This will destroy the fan and
seriously injure nearby people. Observe
the maximum speeds or maximum fre-
quencies and the information on mainte-
nance and repair.
