3 Product overview
3.1 Area of application / Notes on use
The fans / motors are not ready-for-use products, but conceived as components for ventilation
systems (type designation see rating plate).
The fans may not be operated until they are installed in line with their intended use. The supplied and
certified guard grille of ZIEHL-ABEGG SE fans is designed in accordance with DIN EN ISO 13857
Table 4 (from the age of 14 up). In the event of deviations, further structural protective measures must
be taken for safe operation.
•Any use below -10 °C is dependent on not being subjected to unusual, sudden or mechanical loads
or stresses on the material (see minimal permissible ambient temperature).
•Corrosion is possible at the cutting edges on sendzimir galvanised parts.
3.2 Functional description
PMblue stands for fans with PM motors in connection with highest efficiency. Highly efficient electroni-
cally commuted motors with permanent solenoids are used. The electronic commutation and speed
control of the permanent solenoid excited synchronous motor requires a compatible frequency
inverter.
The PMcontrol Basic frequency inverters in the ESDM type series from ZIEHL-ABEGG are designed
for PM motors. Controlling the “PMblue” fan with a PMcontrol Basic requires the data record of the
motor being used. This can be found on the parameter storage medium “ZAstick”which accompanies
this motor.
By transferring the motor and fan parameters to the frequency inverter from ZIEHL-ABEGG, optimum
operation at every operating point is possible thus giving you a drive system of maximum efficiency.
The “ZAstick” is in the terminal box of the PMblue motor on delivery!
Information
"Please pay attention to the additional notes on the parameter storage medium that are featured in
the operating instructions of the PMcontrol Basic frequency inverter.
3.3 Note on the ErP directive
ZIEHL-ABEGG SE wishes to point out that, based on the directive (EU) no. 327/2011 of the Commis-
sion of 30th of March 2011 for enforcing directive 2009/125/EC (hereinafter referred to as ErP
directive), the operational area of certain fans within the EU is bound by certain prerequisites.
The fan may only be used within the EU when it meets the requirements of the ErP directive.
If the said fan does not have a CE mark (cf. especially the rating plate), use of this product within the
EU is not admissible.
All ErP-relevant information comprises measurements which are determined using a standardised
measurement set-up. More details can be obtained from the manufacturer.

4 Mounting
4.1 General notes
Attention!
•Mounting is only to be undertaken by trained service personnel. The system manufacturer or the
machine builder and/or the user is responsible that the inherent installation and security information
are harmonized with the valid standard and guidelines (EN ISO12100 / 13857).
•Check the fan for damage, e.g. cracks, dents or damage to the electric cables, before assembly.
Start-up is not allowed in the case of transport damage!
•Wear safety clothing / shoes and cut-resistant safety gloves when handling.
•At a weight greater than 25 kg for men / 10 kg for women, the fan should be lifted out by two persons
(according to REFA). The values may differ from country to country.
•Lift the fan out of the packaging with a lifting gear (lifting beam). Attachment points are solely the
holes on the housing flange, motor bed, support plate, motor suspensions, fastening brackets and
any crane eyes of the fan (depending on the design of the fan).
•The chain/rope may not touch the impeller and the possibly mounted frequency inverter when lifting
with the lifting beam, otherwise damage is possible.
•The custom designs must suit the prevailing conditions.
•Take into account easy access for cleaning and maintaining the fan.
•Before installing the fan, make sure the safety distances are maintained compliant with EN ISO
13857 or in household equipment according to EN 60335.
–If the mounting height (danger area) above the reference plane is greater than or equal to
2700 mm and is not reduced by auxiliary means such as chairs, ladders, working platforms or
floor space on vehicles, a guard grille is not necessary on the fan.
–If the fan is located in danger zone, then the manufacturer or operator shall ensure that hazards
shall be prevented by appropriare protective constuctions which meet the requirements to EN ISO
13857.
•Protective measures must be taken against falling parts when mounting with a hanging rotor.
•Tighten the fastenings with the specified torques.
•Drilling chips, screws and other foreign bodies must not be located inside the device! Before the first
switch-on, remove any items that may be present (drilling chips, screws and other foreign objects)
from the intake area - risk of injury from any objects that may fly out!
•For fans, the alignment must be adhered to during operation, e.g. if this is indicated by “Oben/Top”.

4.2 Erecting the equipment Design ER
Use screws, for example, of strength class 8.8 according to DIN EN ISO 4014 to fasten the fan.
"Secure the screws with a suitable screw lock.
"Tighten the fastenings with the specified torques ( Table).
"After an operating time of approx. 1 hr. re-check the torque of the screwed connection with the
necessary MA.
Permissible tightening torques M
A
Thread size M6 M8 M10
Property class 8.8, friction coefcient µges 0.12 9.5 Nm 23 Nm 40 Nm
Ensure that the clearance (gap) “a” see fig. between
the fan impeller and the stationary housing section is
constant. Distortion due to uneven surface may lead to
fan failure.
Information
•Every screwing case is different. If the strength class of the screws differs from strength class 8.8,
you must determine the adapted tightening torque by appropriate screw tests.
•Structure-borne noise decoupling of the complete centrifugal fan is recommended to avoid
transmission of disturbing vibrations. (Spring or damping elements are not usually parts of the
standard scope of supply). The assignment of the spacing dimensions of the damping elements can
be taken from the catalogues on our home page under www.ziehl-abegg.de in the section
Download - Ventilation and Control Engineering.
•Erect in the open air only if this is expressly mentioned and confirmed in the ordering information.
There is a risk of damage to the bearings if the fan remains stopped in a moist environment. Avoid
corrosion by suitable protective measures. Roofing is required.
•Corrosion is possible at the cutting edges on sendzimir galvanised parts.
Attention!
•Connect all contact points securely to the foundation or plant. If not fastened sufficiently, there is a
risk of the fan tipping over or coming loose - danger of injury!
•The screwed connection that connects the impeller to the hub may never be loosened for any work
on the fan! The impeller and hub form a commonly balanced assembly which may only be
disassembled and installed as a complete unit. Merely loosening this screwed connection can lead
to imbalance and therefore to vibrations even if the screws are connected again correctly before
recommissioning!
•Blocking or braking the fan by, say, pushing objects into it is forbidden. This leads to heated
surfaces and damage to the impeller.
•Making your own alterations/conversions on the fan module is unacceptable - safety risk!
•Please note the following for all types of centrifugal fans:
–Avoid structural damage or stress with installation. Make sure the surface is flat and even.
–Add-on parts (depending on the design: flanges, fastening brackets, frames, rails, support plates,
etc.) must lie flat on the contact surfaces.
–Do not use force, do not lever, do not bend.
–Do not bend fan roller or fan wheel and blades - imbalance!
–Important: Deformations and misalignments must not result in the striking or grinding of rotating
parts!

4.4 Assembly in a humid atmosphere
Information
If the device is not in use for longer periods in a humid atmosphere, it is recommended to operate the
motor/fan for at least two hours every month at 80 - 100 % of maximum speed to remove any moisture
that has penetrated inside.
4.5 Connection lead & terminal box
Information
In demanding environments (wet areas, open air installation) all connections must incorporate water
drainage curves. To ensure that water cannot penetrate through to the controller housing from the
connections install a terminal box lower than the motor.
4.6 Cable inlet
Attention!
Only use lines which can guarantee a permanent seal around the cable glands (pressure-resistant,
dimensionally-stable, round-centred jacket; e.g. by means of gusset filling)! Lines with filling fleece are
not permissible because moisture can penetrate due to the capillary effect!
The terminal box cover may be opened by technically qualified specialist personnel for the purpose of
laying the connecting cables (DIN EN 50110, IEC 364). Suitable cable glands may be connected to the
terminal box.
"Remove the cover from the terminal box.
"All cable entry points are in a sealed condition at delivery (each 3 on long side). Remove plastic
fastener depending on the need and insert appropriate cable glands (not in scope of delivery). The
manufacturer's specifications for tightening torque and sealing area must be observed! Entry points
that are not used must remain sealed!
"Insert cables properly and ensure tightness of the cable glands.
"Attach the cover of the terminal box again carefully after connection (see Electrical Installation).

5 Electrical installation
5.1 Safety precautions
Danger due to electric current
•Work on electric components may only be carried out by trained electricians or by persons
instructed in electricity under the supervision of an electrician in accordance with electrical
engineering regulations.
•The 5 electrical safety rules must be observed!
•Connect fan only to electrical circuits that can be disconnected with an all-pole isolating switch.
•The device owner is responsible for the EMC of the entire plant according to the locally applicable
standards.
•It is forbidden to carry out work on electrically live parts!
•Cover neighbouring electrical equipment during installation work.
•Cable glands made out of metal are not allowed in plastic terminal boxes due to lack of potential
equalisation.
•Electrical equipment must be checked regularly: Loose connections are to be re-tightened and
damaged cables must be replaced immediately.
5.2 Motor connection
Danger due to electric current
When the motor runs independently due to air flowing through or if it continues to run down after being
turned off, dangerous voltages of over 50 V can arise on the motor connections through operation of
the generator.
Attention!
•Permanent solenoid excited synchronous motors may never be operated directly on mains! A
compatible frequency inverter is always required for electronic commutation. Direct connection to
the mains can lead to destruction of the motor!
•Every permanent solenoid excited synchronous motor must be operated on a separate frequency
inverter. We recommend the use of the PMcontrol Basic frequency inverter from ZIEHL-ABEGG.
•Do not short-circuit the ends of the connections on the motor windings, as this will lead to
demagnetisation of the rotor.

Information
•Please pay attention to the additional notes on connection that are featured in the operating
instructions of the PMcontrol Basic frequency inverter.
•The device size of the frequency inverter is selected on the basis of the maximum motor current as
stated in the fan and motor documentation. The rated current of the frequency inverter must always
be above the maximum motor current of the fan in the desired operating point.
•The connection of the motor to the frequency inverter is made at the terminals: PE, U, V and W.
•The temperature monitors (TP temperature sensor) built into the winding serve as the motor
contactor and must be connected! Pay attention to the permissible maximum test voltage of 2.5 V!

•It is essential to check the direction of rotation of the fan during the initial commissioning. To do this,
note the direction of the arrow on the fan housing. We will not be responsible under any circum-
stances for warrantee for damage caused because the direction of rotation is wrong!
•If the connection to the PMcontrol Basic frequency inverter is implemented correctly (see enclosed
connection diagram) and if the correct motor parameters are transferred to the frequency inverter,
then operation with the correct turning direction is ensured. If it should be necessary to reverse the
turning direction, however, this can be done by interchanging two motor phases.
6 Start-up
6.1 Prerequisites for commissioning
Attention!
•During commissioning, unexpected and hazardous conditions can arise in the entire installation due
to defective adjustments, defective components or incorrect electrical connections. Remove all
persons and objects from the hazardous area.
•Do not start the fan until all safety instructions (DIN EN 50110, IEC 364) have been checked, the fan
is out of range (DIN EN ISO 13857) and danger can be ruled out.
•A-rated sound power levels of over 80 dB(A) are possible, see product catalogue.
Before first-time start-up, check the following:
1. Installation and electrical connection have been properly completed?
2. Has any leftover installation material and other foreign material been removed from the fan area?
3. Sicherheitseinrichtungen - falls erforderlich - montiert (EN ISO 13857)?
4. The impeller is out of reach?
5. Are the drain holes (as far as available) open or respectively closed according to the suitable
installation position?
6. Connection data complies with the specifications on the rating plate?
During start-up check the following:
1. Check the direction of rotation (see rotation direction arrow on the fan blade, impeller base plate
or support plates on suction side or rating plate).
2. Check for quiet, low vibration operation. Strong vibrations due to erratic operation (unbalanced),
e.g. caused by transportation damage or improper use, can lead to failure.
3. If resonance vibrations occur, it is possible to hide certain speed ranges (see Motor Setup).
4. Fans from ZIEHL-ABEGG SE are delivered balanced in accordance with DIN ISO 21940-11 for
the appropriate fan category in accordance with ISO 14694 Check the fan for mechanical
vibrations after installation. If the limit values of the corresponding fan category are exceeded in
start-up, you must have the motor/impeller unit checked by an expert and rebalanced if necessary
before continuous operation is permitted.

8 Service work
8.1 Repairs / maintenance
Attention!
•Please read the Safety instructions chapter before working on the fan!
•Before working on the fan, this must be disconnected from the power supply and secured against
switching back on!
•No maintenance work at running fan!
•Allow maintenance work to be carried out by trained specialists only.
•Any faults detected in the electric system/modules/operating equipment must be corrected
immediately. If these faults are not corrected, the device/system is potentially very dangerous. The
device/system must therefore not be operated when it is faulty.
•Wear safety clothing / shoes and cut-resistant safety gloves when handling.
•Please observe the safety regulations and the worker´s protection rules by all maintenance and
service work (EN 50 110, IEC 364).
•Fuses must always be only replaced; never repaired or bridged. The specifications for the maximum
series fuse must always be adhered to (see Technical data). Only fuses cited in the electrical circuit
diagram may be used.
•Generator operation can produce dangerous voltages (see safety instructions)!
•Keep the airways of the fan free - danger because of objects dropping out!
•Watch out for vibration free motion!
•The impeller is subject to natural wear depending on the area of application and the conveying
medium. Deposits on the impeller can lead to imbalance and damage (danger of permanent
fracture). The impeller can burst!
•If highly aggressive media for which the product is not suited are conveyed, the severe corrosion
may result in the impeller breaking. Any impellers corroded in this way must be replaced
immediately.
•Deposits on the motor, particularly on the cooling vanes and in recesses on the rotor, can lead to
reduced cooling performance and the motor switching off prematurely. For this reason, remove
deposits quickly (see chapter: Cleaning).
•Maintenance interval in accordance with the degree of contamination of the impeller!
•Check the fan at regular intervals (recommendation: every 6 months) for mechanical oscillations.
Observe the limits specified in ISO 14694 and, if they are exceeded, implement remedial measures
(e.g. rebalancing by specialist staff).
•Check the impeller, in particular the weld-seams, for possible cracks.
•Repair, e.g. by welding is prohibited!
•Bolted-on impellers and/or wings may only be replaced by authorised ZIEHL-ABEGG SE staff. The
manufacturer shall not be liable for damage caused through improper repair work.
•Please consult our service department with regard to changing the bearing as for all other damage
(e.g. to the coil).
•Regular inspection and possibly cleaning is necessary to prevent imbalance and blockage of the
drain holes due to ingress of dirt.
•When opening cable glands on the fan / motor, check the condition of the threaded connections and
seals. Always replace defective or brittle threaded connections and seals.
