2.4 Product safety
The device conforms to the state of the art at the time of delivery and is fundamentally
considered to be reliable. The device and its accessories must only be used in a flawless
condition and installed and operated in compliance with the assembly instructions and/or
operating instructions. Operating outside the device's technical specifications (see name
plate and attachment / technical data) can lead to a defect in the device and additional
damage!
Information
A separate fault and performance monitoring-system with an alarm signal function is
necessary in order to prevent personal injuries and material damages during malfunc-
tions and in case the device fails. Substitute operation must be taken into consideration!
The design and installation of the system must comply with local regulations and
directives.
2.5 Requirements placed on the personnel / due diligence

servicing in connection with the frequency inverter must have the corresponding qual-
ifications and skills for these jobs.
In addition, they must be knowledgeable about the safety regulations, EU/EC directives,
rules for the prevention of accidents and the corresponding national as well as regional
and in-house regulations. Personnel to be trained or instructed and apprentices are only
permitted to work on the device under the supervision of an experienced person. This
also applies to personnel undergoing general training. Comply with the legal minimum
age.
2.6 Work on the device
Information
Mounting, electrical connection, and start-up operation may only be carried out by an
electrical specialist in accordance with electrotechnical regulations (e.g. EN 50110 or
EN 60204)!
Danger due to electric current
•It is generally forbidden to carry out work on electrical live parts. Protection class of the
device when open is IP00! It is possible to touch hazardous voltages directly.
•The rotor is not protected against indirect contact neither by supplementary or
reinforced insulation nor by connection to safety-earth in accordance with EN 60204-
1, therefore the system constructor must provide protection by enclosure in
accordance with EN 61140 before the motor is connected to a power source. This
protection can be achieved for example by a guard grille (
Product overview:
Application operational area and Installation: General).
•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
internal connections through operation of the generator.
•The safe isolation from the supply must be checked using a two-pole voltage
detector.
•Even after disconnecting the mains voltage, life-threatening charges can appear
Assembly instructions ECblue Basic Safety instructions
L-BAL-F052D-GB 1803 Index 006 Part.-No.
9/59

between the protective ground “PE” and the mains connection.
•The protective earth is conducting high discharge currents (dependent on the
switching frequency, current-source voltage and motor capacity). Earthing in
compliance with EN specifications shall therefore be observed even for testing and
trial conditions (EN 50 178, Art. 5.2.11). Without earthing, dangerous voltages can be
present on the motor housing.
•Maintenance work may only be carried out by suitably qualified personnel.
Waiting period at least 3 minutes!
•Through use of capacitors, danger of death exists even after switching off the device
through directly touching the energized parts or due to parts that have become
energized due to faults.
•The controller housing may only be removed or opened when the power line has been
switched off and a period of three minutes has elapsed since switching it off.
Attention, automatic restart!
•The fan / motor may switch on and off automatically for functional reasons.
•After power failure or mains disconnection an automatic restart of the fan takes place
after voltage return!
•Wait for the fan to come to a complete standstill before approaching it!
•The exterior rotor turns during operation of the external rotor motor!
Danger of being sucked in!
Do not wear loose or hanging clothing, jewellery, etc., tie together long hair and cover it.
Attention, hot surface!
•Temperatures of above 85 °C can occur on the motor surfaces, especially on the
controller housing!

3 Product overview
3.1 Application operational area
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.
3.2 Functional description
ECblue stands for EC fans and motors with maximum efficiency. Highly efficient, elec-
tronically commutated motors with permanent magnets are used the speed of which is
controlled by the integrated controller.
The devices are constructed in accordance with the general requirement in EN 61800-2
for adjustable speed electrical power systems and is intended for one-quadrant drives.

3.3 Criteria for long service life
The service life of devices with power electronics is decisively dependent on the ambient
temperatures. The longer electronic components are exposed to high ambient temper-
atures, the faster the deterioration and the more probable the failures.
The device is designed with a service life of at least 40,000 h when S1 operated at full
power in the maximum permissible ambient-temperature environment.
In order to achieve this, the power electronics protects itself against excessive temper-
atures by active temperature management.
However, this cannot provide complete protection in all circumstances. Observe the
rated data - particularly the maximum permitted ambient temperature - on the rating
plate.
3.4 Note on the ErP directive
ZIEHL-ABEGG SE wishes to point out that, based on the directive (EU) no. 327/2011 of
the Commission 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.
Further information about the ErP directive (Energy related Products-Directive) can be
found on www.ziehl-abegg.de search key: "ErP".
3.5 Transport, storage
Attention!
•Observe the weight specifications (see rating plate) and the permissible carrying
loads of the means of transport.

4 Mounting
4.1 General notes
Attention!
•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!
•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 ISO 12100 / 13857).
•Wear safety shoes and gloves for handling!
•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 shape 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.
•At a weight greater than 25 kg for men / 10 kg for women, the device should be lifted
out by two persons (according to REFA). The values may differ from country to
country.
•Prior to installing the fan, it is to be checked whether the safety zone as per EN ISO
13857 and in household appliances as per EN 60335 are met. If the installation height
(danger zone) above the reference level is greater than or equal to 2700 mm and is
not reduced by auxiliary means such as chairs, ladders, work platforms or bases on
vehicles, a guard grille against accidental contact is not necessary at 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.
•The custom designs must suit the prevailing conditions.
•Tighten the fastenings with the specified torques.
•Do not allow drilling chips, screws and other foreign bodies to reach the device
interior!
•Any use below -10 °C is dependent on not being subjected to unusual, sudden or
mechanical loads or stresses on the material (min. ambient temperature
Technical
data).
•Corrosion is possible at the cutting edges on sendzimir galvanised parts.
•Before the first switch-on, remove any items that may be present (borings, screws and
other foreign objects) from the intake area - risk of injury from any objects that may fly
out!

4.2 Connection lead & terminal box
Information
"In demanding environments (wet rooms, outdoor installation), connecting cables must
have water draining pipe elbows.
"If using a terminal box, install this lower than the motor to ensure that water cannot
penetrate through to the controller housing from the connecting cables.
Do not coat connection components!
•Coating connecting cables, cable glands and electronics covers (e.g.
by painting, lacquering, powder-coating), is not permissible without
consulting ZIEHL-ABEGG!
•Painting the cover is only permissible with paints approved by
ZIEHL-ABEGG!
4.3 Assembly in a humid atmosphere
Information
If a fan / motor is stationary for long periods in a humid atmosphere, it should be switched
ON for minimum of two hours every month to remove any moisture that may have
condensed within the motor.
4.4 Motorheating
A continuous power supply is required for safe operation down to the minimum permitted
ambient temperature (see technical data).
If the motor is not switched on with an existing power supply (no setting signal, switch off
by enable), the motorheating switches back off automatically at a controller inside
temperature of -19 °C and heating up to -15 °C.
Heating takes place via the motor winding whereby a current is induced which cannot
cause rotation.
