2.4 Appropriate Use
The product is to be used exclusively for
the intended use described herein.
The fans are only suitable for conveying
gaseous media without solids. Solids or
impurities contained in the conveying
medium must be filtered out before en-
tering the fan.
The intended use also includes:
•The temperature of the conveying
medium must be between -4.0°F (-
20°C) and +176.0°F (+80°C) in the
series version.
•The temperature of the conveying
medium must be between -4.0°F (-

12 TXP Inst. & Maint. Manual: IM-

20°C) and +356.0°F (+180°C) for
special versions with heat shield.
•The fan is designed for S1 opera-
tion (continuous operation) and S9
operation (uninterrupted operation
with non-periodic load/speed
change) (according to IEC 60034-
1). By way of derogation, a maxi-
mum of 27 circuits per hour are per-
mitted.
•In the case of damp media, a con-
densation bore can be ordered.
This is introduced into the housing
by the manufacturer.
The product may only be used if:
•This is in technically perfect condi-
tion
•The staff has the necessary safety
and danger awareness.
•The instructions in the operating in-
structions are followed.
2.5 Predictable Misapplication
For a purpose other than the intended
use listed here, the fan is not intended.
In principle, a use other than the in-
tended use is considered to be im-
proper. This means that safe operation
is no longer guaranteed. The operator
and not the manufacturer is responsible
for all personal injury and property dam-
age resulting from the improper use.
Predictable misuse also includes:
•The promotion of:
-Aggressive media
-Abrasive media
-Adhesive media
-Toxic media
-Explosive media
-very humid (with drop for-
mation) media
•Installation in an explosive atmos-
phere
•Series or parallel connection of sev-
eral fans
•Outdoor installation without special
measures
•Conversion and modification
2.6 Conversions and Changes
Modifications to the fan are not permit-
ted for safety reasons.
The use of non-original spare parts may
remove liability for the resulting conse-
quences. Therefore, always use only the
predetermined spare parts, this applies
especially to safety-relevant compo-
nents (impeller, motor, ball bearings,
runners, etc.).
2.7 Residual Risks
Electric fans are built according to the
state of the art and are characterized by
a high degree of operational reliability.
Since the fans are very powerful ma-
chines, the following safety instructions
must be strictly observed in order to
avoid injury, damage to property and the
machine itself.
Overview of Danger Points
The residual hazards of the fan are di-
vided into the following four areas:

Table 3: Assignment of residual hazards
For more information, see the following
chapters.
2.7.1 Hazards from Fans
Many residual hazards come from the
fan itself and are due to its intended
use. During operation, the impeller ro-
tates inside the fan and this can lead to
risks. As a protective measure against
these risks, the fan has a housing and a
protective grille on the suction side that
prevents the contact of the dangerous
areas. In the case of free-blowing fans,
a protective grille must be added on the
pressure side (available as an acces-
sory). Furthermore, pictograms inform
about potential danger points.
Dangers from moving in
During the operation of the fan, the im-
peller rotates at high speed. The air is
sucked in via the intake port. People

14 TXP Inst. & Maint. Manual: IM-
825
and objects in the vicinity can also be
sucked in.
WARNING!
Danger from being drawing
in at the intake port
During operation, air is
sucked in through the intake
port. Loose clothing, personal
jewelry, scarves or long hair
can be sucked in. The conse-
quences are mild to severe
physical injuries, such as
shortness of breath due to
strangulation, abrasions, skin
injuries, etc.
Wear tight fitting clothing
Wear a hair net
Take off personal jew-
elry such as necklaces
or bracelets before
working on the fan.
Do not wear ties or
scarves
Keep away from the
suction opening during
operation
Check the condition of
the protective grille regu-
larly
Wear h
ead protection, such as
hairnet, beanie, hairband,
For long hair, wear a hairnet, a
beanie
or a hairband so that it is
not possible to insert the hair into
the fan
.
Danger from unexpected start-up of
the fan
The fan and its housing must be opened
during cleaning, maintenance and repair
work. In these situations, unexpected
start-up of the fan carries a great risk.
Therefore, the product must be discon-
nected from the power supply before
these works and secured against re-en-
try. Then wait for all moving parts to
stop. Only then can work on the product
be carried out.
Unexpected start-up can cause hazards
due to being drawn in if the fan starts
unexpectedly, hair, clothing or jewelry
can be sucked in and cause injury.
Disconnect the product from the voltage
even in the event of an unexpected fail-
ure or interruption of the power supply.
This prevents the product from coming
out unexpectedly and endangering peo-
ple nearby.
Danger from ejected parts
WARNING!
Risk of injury due to
ejected parts
When impurities or objects
enter the interior of the prod-
uct, they are ejected from the
blow-out nozzle at high
speed during operation. Peo-
ple affected by this suffer se-
rious injuries.
Promote only pure me-
dia without solids
Do not stay in the dan-
ger zone
Adhere to maintenance
and repair information
Wear protective gog-
gles
The fan is designed to convey clean air.
The protective grille at the intake

TXP Inst. & Maint. Manual: IM
-825
15
opening prevents access to the inside
of the fan and also prevents larger for-
eign bodies from being drawn in.
Smaller foreign bodies and particles in
the sucked-in air can still enter the in-
side of the product and are deposited
there as impurities or are immediately
ejected again. Deposits can damage the
fan or be ejected from the exhaust vent
at high speed during operation. People
who are hit by ejected parts can suffer
serious injuries.
Danger from rotating parts
WARNING!
Risk of injury due to rotat-
ing parts
The fan impeller rotates at
high speed during operation.
If people reach into the rotat-
ing impeller, fingers or limbs
can be severed..
Do not reach into the
inside of the fan during
operation
Check regularly
whether the necessary
protective grilles are
present at the open-
ings and are intact
Replace missing or
damaged protective
grilles immediately
Wait until the impeller
stops before removing
protective grilles for
maintenance
After completion of
maintenance work, in-
stall all protective
grilles again. An inter-
vention in the inside of
the fan must be pre-
vented.
The impeller inside the fan rotates at a
high-speed during operation. If objects
or limbs are put into the rotating impel-
ler, serious injuries are at risk. In addi-
tion, these may be further retracted into
the impeller.
This residual hazard is an important part
of the function of the product. Without a
rotating impeller, media cannot be

16 TXP Inst. & Maint. Manual: IM-
825
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
Use"
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.

Hazards from sharp edges, corners
and tips
CAUTION!
Risk of cutting due to
sharp edges, corners and
tips
Touching these areas can
lead to minor cuts.
Wear protective gloves
The impeller inside the fan has sharp
edges, corners and tips. Touching these
areas can lead to minor cuts. To avoid
these, the posts were deburred as far as
possible. In addition, the protective grille
on the suction opening prevents the
intervention in the housing and warning
signs on the fan warn of the danger.
Check the condition of these protective
measures regularly and replace them in
the event of damage.
Hazards due to the weight of the fans
During transport or installation of the
fan, there is a risk of the fan tipping over
or falling. In these situations, the fan is
not yet firmly screwed and its own
weight can injure people. Secure the fan
with suitable fasteners during transport
or installation and follow the instructions
in this manual.
2.7.2 Hazards from electrical en-
ergy
The electrical connection of the product
to the supply network as well as work on
the electrical equipment may only be
carried out by qualified electricians, con-
sidering the relevant standards and reg-
ulations.
The electrical components of the prod-
uct must be checked at regular intervals.
Defects, such as loose connections,
grated or simmered cables, must be rec-
tified immediately.
Keep moisture away from tension-carry-
ing parts. Moisture can cause short cir-
cuits.

sionals or electrically
instructed persons un-
der the guidance and
supervision of an elec-
trical specialist in ac-
cordance with the elec-
trotechnical rules
The workspace must
be locked with a red-
and-white safety chain
and a warning sign
The safety rules for
carrying out work on
electrical installations
and equipment must
be followed
Security policy
Observe the following safety rules for
carrying out work on electrical installa-
tions/equipment:
1. Disconnect the power supply
2. Secure against re-entry
3. Detect freedom of tension
4. Earth and short-circuit
5. Cover or barriers to adjacent, tense
parts
2.7.3 Exposure to noise
The fan causes noise during operation.
This residual hazard cannot be elimi-
nated as it is the result of the function of
the fan. Increased noise exposure can
lead to hearing damage or other health
damage. Therefore, always wear a
hearing protector and stay in the envi-
ronment of the fan only when neces-
sary.
WARNING!
Hearing damage due to
noise
Staying without hearing pro-
tection in the vicinity of the
running fan can lead to hear-
ing damage.
Wear a hearing protec-
tion from a daily expo-
sure level of 80 dB(A)
and/or a peak sound
pressure level of 135
dB(C).
The noise emitted by the fan is not con-
stant over the entire power range. The
radiated noise levels can be found in the
technical data.
The operator must perform a measure-
ment on the fan. If the statutory maxi-
mum values at workplaces are ex-
ceeded, the operator must carry out
sound insulation.

TXP Inst. & Maint. Manual: IM
-825

Sound insulation of any kind shall not
result in an undue increase in the ambi-
ent temperature above +104°F (+40°C)
on the drive motor.
2.7.4 Hazards from the
environment
Accessibility and location of the fan are
important safety factors. Therefore,
when installing and installing the fan,
ask yourself the following questions:
•How easy is it for outsiders to get
access to the facility?
•Does the fan pose a danger to the
environment?
•Has the system been tuned for the
application?
•Are additional safety precautions,
such as protective fences, neces-
sary?
•Can service or maintenance per-
sonnel easily shut down the fan via
accessible switches and secure it
against re-switching?
All these issues are relevant to security.
Only with respect for these aspects can
the fan be operated properly and safely.
2.7.5 Thermal hazards
Hot surfaces on the fan housing
The fan housing assumes the tempera-
ture of the conveying medium during op-
eration. If this is above +122°F (+50°C),
the fan must be protected by the opera-
tor from direct contact. Touching hot
surfaces can lead to burns.
When conveying from the intake side to
the blow-out side, the temperature in the
conveyed medium can be increased.
Depending on the operating conditions,
this temperature difference can be in a
range of up to +176°F (+80°C) depend-
ing on the type.
WARNING!
Risk of burning due to hot
surfaces
Surfaces of the fan can heat
up. Prolonged contact (>1
sec) with these surfaces can
cause burns.
Avoid touching the hot
surfaces
Turn off the fan and
wait until the surfaces
have cooled down
Hot surfaces on the engine
The motor housing heats up during op-
eration. If the temperature rises above
+122°F (+50°C), the fan must be pro-
tected by the operator from direct con-
tact. Touching hot surfaces can lead to
burns.
WARNING!
Risk of burning due to hot
surfaces
Surfaces of the fan can heat
up. Prolonged contact (>1
sec) with these surfaces can
cause burns.
Avoid touching the hot
surfaces
Turn off the fan and
wait until the surfaces
have cooled down

2.7.6 Hazards due to resonances
and vibrations
WARNING!
Risk of injury due to com-
ponent failure
Operation with resonances
and vibrations can damage
the fan and cause the impel-
ler to break. Fragments are
thrown out of the fan and can
injure bystanders.
When commissioning,
measure the vibrations
Do not operate the fan
in resonance mode
Follow the instructions
for transport, storage
and installation de-
scribed in the instruc-
tions
Prevent impacts on the
fan
Skip or block areas
with increased vibra-
tion values
We recommend the
use of permanent vi-
bration monitoring for
speed-controlled fans
Risk from Vibrations
Typical damage to fans is caused by im-
permissible vibrations. If the fan is oper-
ated with impermissible vibrations for a
long time, this will affect the service life
of the entire product. Vibrations can
loosen screw connections and damage
ball bearings. In the worst case, parts
break and are thrown out of the vent. If
people are hit by these parts, this can
lead to serious injuries or death.
Risk from Resonances
Every component on the fan has its own
natural frequencies. These can be ex-
cited by certain speeds of the fan, which
leads to a possible resonance opera-
tion.
The resonance operation can lead to
mechanical destruction of the fan and
the associated personal injury. There is
danger to life. The fan must not be oper-
ated in resonance mode. The fans are
designated in such a way that reso-
nances usually do not occur.
If the speed changes during operation,
an excitation can occur in under certain
circumstances. These circumstances
are also influenced by the customer-
specific installation situation or the venti-
lation connection.
If operating frequencies of the fan lead
to resonance operation, these must be
excluded by appropriate parameteriza-
tion of the frequency converter.
The fan should be installed and commis-
sioned by specialists with experience in
handling fans. Adhere to the information
in the operating instructions to prevent
damage.
2.7.7 Hazards when operating
multiple fans
If the fan is operated in combination with
other fans in a system, additional resid-
ual hazards are created. Therefore,
when working on systems with multiple
fans, always switch off all fans that can
cause a hazardous situation.
The following situations may occur when
working in multi-ventilator systems:
•The impeller of the fan does not
stand still despite the separation of
