• Ensure the suitable load capacity and properties of the mounting surface and
use suitable mounting material.
• The installation area must be designed so that people cannot be endangered
by drawn-in objects.
• The outlet area must not be accessible to persons
• When working or standing in the vicinity of the running fan, ear protection
may be necessary depending on the size of the fan!
• The operator is responsible for observing all plant-related safety regulations!
• Abnormally frequent activation/deactivation is not permissible.

ning work!
• A uniform inflow and free outlet must be ensured.
1.3

Application

– Normal use:
The fan is suitable for continuous operation S1 for conveying normal or slightly dusty (particle size < 10 µm), less ag-
gressive and humid air, in moderate climates at temperatures in the range of -30 °C to +40 °C, with stationary instal-
lation of the fan. Increased temperatures according to catalogue or type plate information.
– Reasonably foreseeable misuse:
The fans are not suitable for operation under difficult conditions, such as high levels of humidity, aggressive media,
long standstill periods, heavy contamination, excessive loads due to climatic, technical or electronic influences. The
same applies for the mobile use of fans (vehicles, aircraft, ships, etc.).
– Improper, prohibited use:
Fan operation with incorrect rotation direction cf. 1.7. Outdoor installation without effective weather protection or in
direct contact with water. Conveyance of explosive gas mixtures/media. Installation in an explosive area/atmosphe-
re. Operation without standardised safety devices (e.g. protective grille). Conveyance of solids or solid content > 10
µm in the conveyed medium and liquids. Conveyance of abrasive and/or fan material-corrosive media. Conveyance
of conveyed medium containing fat.
1.4

Boundaries

Spatial boundaries:
A straight, flat pipe section of 2.5*D must be ensured before and after the fan. When using a pipeline at the start, a
suction nozzle must be used and the intake area must not be obstructed within 2.5*D. Extension pipes before the fan
are not necessary. When using a pipeline at the end, there must be a straight section of pipe of 2.5*D after the fan.
The outlet-side environment must not be accessible to unauthorised persons and obstructed. The fan must be easily
accessible for cleaning and maintenance purposes, particularly the terminal box/isolator switch.
Power supply interface:
– Connection only with permanently installed lines
– 3 phases + PE + 2x TB(TK) or TP(KL) or 1 phase + N + PE + 2x TB(TK) or. TP(KL)
– A motor protection device is mandatory for all 3~ units
1.5

Protection against contact

The generally applicable safety at work and accident prevention regulations must be observed for installation!
The operator is responsible for observing these regulations!
– Contact with rotating parts must be avoided. It must be ensured that there must be no persons, textiles or other
materials that could be sucked up, such as clothing, located in the intake area.
– Protection against contact may be necessary on the suction side depending on the installation conditions.
Appropriate protection grilles are available as accessories.
– Fans which are protected by their installation method (e.g. installation in ventilation ducts or closed assemblies) do
not require protection guards if the plant provides the necessary level of safety. Please note that the operator is
responsible for complying with the current standard (DIN EN 13857) and can be held liable for accidents as a con-
sequence of missing protection systems.
