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 (
rating
plate and attachment / technical data) can lead to a defect in the device and additional
damage!
A separate fault and performance monitoring-system with an alarm signal function
is necessary in order to prevent personal injuries and material damages during
malfunctions 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.

Persons entrusted with the planning, installation, commissioning and maintenance and
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 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.
This device is not intended to be used by people (including children) who have restricted
mental, sensory or intellectual abilities or who have a lack of experience and/or knowl-
edge.
2.6 In the Operation
Danger due to electric current
•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.

Attention, danger of being sucked in!
•Danger of being sucked in: Do not wear loose or hanging clothing, jewellery, etc.,
tie together long hair and cover it.
2.7 Working on device / Hazards through “residual voltage”
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 IP 00! 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
between the protective earth “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.

3.3 Ziehl-Abegg design 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 device protects itself by active temperature management.

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 DIN EN ISO 13857.
•Custom designs must suit the prevailing conditions.
•Tighten the fastenings with the specified torques.
•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).
4.2 Connection lead & terminal box

4.5.2 Erecting the equipment: Design ER...-..N... / ER...-..K... / GR...
•To avoid the transference of disruptive vibrations, we recommend de-coupling the
entire plug fan to avoid sounds transmitted through solids. (Spring and/or attenu-
ation units are not a constituent part of the standard scope of delivery). Look at
our catalogue for positioning the decoupling elements or request a dimensions
sheet stating the type designation and Part.-No.
•Attention: All contact points must be fixed securely. If the fixing is inad-
equate there is a risk of the fan overturning.
•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.
•Making your own alterations/conversions on the fan module is unacceptable -
safety risk.
•In the case of a vertical motor axis, the respective lower condensation drain hole
(if available) must be open.
4.5.3 Optimal installation distances according to for RH../ ER../ GR.. fans
•Distance on suction side: LA ≥ 0.5 x DSa*
•Distance on the pressure side: LD ≥ 1 x DSa

•During assembly of the fan impellers or other components, no inadmissible force
may be applied to the motor bearing.
•Centre the fan impeller accurately and mount without tension on the rotor flange,
the fan wheel must lie flat.
•Use suitable screws for fastening the fan impeller on the rotor flange and fit as
suitable screw lock.
•Every screwing case must be tested for suitability.
•The permissible area pressing of the steel flange may never be exceeded
(depending on the contact surface).
•Too great a screw overhang is not permitted and can lead to scraping or blocking
of the rotor on the fixed motor flange.
•Motors are not balanced as standard, a complete balancing with mounted fan
impeller is necessary. The balancing must be done on the fan impeller. The
pertinent regulations must be observed.

5.4.3 Required quality attributes for the mains voltage
Danger due to electric current
The mains voltage must comply with the EN 50160 quality characteristics and the
defined standard voltages in IEC 60038!
5.4.4 Operating in IT-System
Information
• 3 ~ ECblue types are only in special version “IT” for the employment in IT-
System suitable! Special version “IT” not UL approved, line voltage
Technical
data.
• 1 ~ ECblue types can be used in IT-System in standard version. These may only
be used in 3 ~ IT-Systems if no higher voltage to the “PE” can occur than the
specified mains voltage of the device even in case of a fault to earth of a mains
phase which is not used by the device (of none of the two power supplies).
In order to ensure a trouble free operation in IT-System the “GND” potential of the
control ports have to be connected with the protective earth potential.
As a consequence of these connection must be considered for the control ports (excep-
tion floating relay contacts):
1. Connection only with wires, suitable for mains voltage and surrounding area.
2. Connection with suitable isolated amplifiers only.
Danger due to electric current
•In the IT-System the neutral point of voltage supply is not grounded; in the case of
a short-circuit between a phase (e.g. “L1”) and protective earth “PE” becomes the
protective earth potential = L1.
•Between the mains connection of the device and the protective earth “PE” is
in no case a higher voltage permissible than the indicated line voltage of
the device!

2. Has any leftover installation material and other foreign material been removed
from the fan area?
3. That safety devices -if necessary- are mounted (EN ISO 13857)?
4. The impeller is out of reach?
5. Are the condensation water drains holes open or respectively closed according
to the suitable installation position?
6. Connection data complies with the specifications on the type plate?
•Commissioning may only take place if all safety instructions have been
checked and danger can be excluded.
–Check the direction of rotation (
rotation direction arrow on the fan blade,
impeller base plate or on the fan housing).
–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.
–A-rated sound power levels of over 80 dB(A) are possible, see product
catalogue.
–Check for mechanical vibrations after installation into the system. If the
tolerances according to ISO 10816-1 are exceeded, it is possible to exclude
certain speed ranges (
Motor Setup or add-on module).

Active temperature management
The device has an active tempera-
ture management to protect it from
damage due to too high inside tem-
peratures. In case of a temperature
rise above the fixed limits, the modu-
lation is reduced linearly. To prevent
the complete system being switched
off externally (in this operation per-
missible for the controller) in case of
reduced operation due to too high an
internal temperature, no fault mes-
sage is sent via the relay.
With a drop in temperature the mod-
ulation rises again llinear.

7.3 Behaviour in rotation by air current in reverse direction
In the STOP state (no release, no preset signal, no voltage supply) the motor controller
does not intervene when the fan turns in the wrong direction (e.g. due to a draught).
If the fan is started while being driven in the opposite direction to that set, the speed is
reduced controlled to “0” and restarted in the set direction of rotation.
The higher the speed to be reduced, the longer this process lasts.
In cases in which the fan is driven very powerfully in the wrong direction, it may not be
possible to start the fan with the set direction of rotation.
Information
•Do not switch off line voltage that the fan can start again!
•Safe starting of fans is not guaranteed if it is started in reverse. If the application
demands safe starting, the machine manufacturer or owner must prevent reverse
driving rotation by suitable measures.

8 Service work
8.1 Repairs / maintenance
Attention!
•Allow maintenance work to be carried out by trained specialists only.
•Please observe the safety regulations and the worker´s protection rules by all
maintenance and service work (DIN EN 50 110, IEC 364).
•Before working on the fan, this must be disconnected from the power supply and
secured against switching back on!
•Keep the airways of the fan free - danger because of objects dropping out!
•No maintenance work at running fan!
•Watch out for vibration free motion!
•Depending on the application and the transfer medium the impeller has a natural
wear. Deposits on the impeller can lead to imbalance and thus to damages
(danger of endurance fracture). The impeller can disintegrate!
•Maintenance interval in accordance with the degree of contamination of the
impeller!
•In case of imbalance: Rebalance the impeller.
•Check the impeller, in particular the weld-seams, for possible cracks.
•Repair, e.g. by welding is prohibited!
•The fan or motor is maintenance-free due to the use of ball bearings with “life-long
lubrication”. At the end of the grease life (
Technical Data) it is necessary to
change the bearing. Please consult our Service Department in this case as for all
other damage (e.g. to the coil or electronics).
•Bolted-on wheels and/or wings may only be replaced by authorised Ziehl-Abegg
AG staff. The manufacturer shall not be liable for damage caused through improp-
er repair work.
•Regular inspection, and cleaning is necessary to prevent imbalance due to in-
gress of dirt.
8.2 Cleaning
Danger due to electric current
Voltage supply for motor must be interrupted and secured against restoration!
Attention!
•Do not use any aggressive, paint solvent cleaning agents when cleaning.
•Cleaning with a water jet:
–Make sure that no water gets into the inside of the motor and electronics, note
protection class (IP).
–Do not hold the jet spray directly on the motor openings and seals.
–During cleaning work using a jet spray, no guarantee is assumed regarding
corrosion formation / paint adhesion for unpainted / painted fans.

For further information to UL types
connection diagram.
9.1.2 UL: Overload protection
The integrated variable speed drives are equipped with a solid state motor overload
protection and a solid state short circuit protection.
The solid state motor overload protection protects the motor under overload conditions
by reducing current flow to the internal motor output terminals. This protection is
achieved through algorithms based on I
2
t of the current of the motor.
The overload protection circuitry is optimally configured to the specific motor and the
specific final application of the integrated variable speed drive.
This is typically 100 % of the full-load current of the motor. Changing the settings of the
solid state motor overload protection needs further discussion with Ziehl-Abegg AG.
Changing the settings without written permission of Ziehl-Abegg AG is not allowed.
The solid state short circuit protection acts to suspend current flow to the internal motor
output terminals upon sensing output current to the motor and bus voltage. The protec-
tion of the motor is comprised of hardware and firmware.
