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.
2.5 Requirements placed on the personnel / due diligence
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.

•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!
•In the AC external rotor motor the external rotor turns during operation!
Attention, hot surface!
•Temperatures of above 85 °C can occur on the motor surfaces, especially on the
controller housing!

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.

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
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 fan.

4.3 Connection according UL and CSA in different applications
4.3.1 Connecting the conduit for NEC and CEC approval
Conduits
Attention!
The fan type ECblue, series MK116 and MK152 with integrated variable speed drives,
for the North American economic region (noticeable on the rating plate) are approved as
power conversion equipment according to UL508C.
Furthermore, the motors have environmental type rating class 3 according UL50(E) for
outdoor use.
Compliance with the following specifications is mandatory for this:
•Metric to inches threaded adapters, used to connect the conduits, can be ordered
from Ziehl-Abegg AG in a package of 3:
–for MK116: part number 00297623
–for MK152: part number 00297624
•These are to be used to connect the motor in accordance with the specifications
of the NEC
®
(National Electrical Code, ANSI/NFPA 70) and UL508 corresponding
to the circumstances onsite.
•The electrician / plant contractor is responsible for correct connection of the
adapter and the conduits so that no damage can occur due to infiltrating moisture
or water. When sealing the conduit connections make sure the supplied O-rings
are used. When screwing the conduits into the thread adapters, use UL approved
sealing tape (e.g., Teflon tape).
•The locking screws used within the MK116 and MK152 series are only for ship-
ment. For installation the locking screws must be removed.
•It must be used a connection technology suitable for the environmental type rating
of the drive!

Alternative: flexible connection
If the connection of the conduits is not possible with the thread
adapter due to a lack of installation space, Ziehl-Abegg recom-
mends its customers use an UL514B approved flexible connection
hose system.
As an example it can also be used on equipment and machines.
However, applicable here is that the equipment / machine must be
configured / approved in accordance with UL508.
Possible suppliers: - Anamet, - Flexa GmbH, - Thomas & Betts
Attention! Ziehl-Abegg cannot provide any warranty on the envi-
ronmental type rating, class 3 for this.
Independent of the type and manner of the conduit / tube connection, correct connection
of the supply line(s), the safety of people and objects must be provided at all times.
4.3.2 Connection in NFPA 79 Applications
In applications where the NFPA 79 (Electrical Standard for industrial machinery) applies
the enclosed cable glands can be used.
The cable glands can be ordered additionally in packages of 3 from Ziehl-Abegg:
•for MK116: part number 00295308
•for MK152: part number 00296715
Attention!
•Independent of the type and manner of the conduit / tube connection, correct
connection of the supply line(s), the safety of people and objects must be provided
at all times.
•The locking screws used within the MK116 and MK152 series are only for ship-
ment. For installation the locking screws must be removed.

Information
•Pay attention to a sufficient screw-in length in the motor flange.
•Excess screw length not permissible and it may result in the rotor being brushed
against or blocked.
•Every screwing case is different. The tightening torque adapted to it must be
determined by the appropriate screw tests.
•Avoid structural damage or stress with installation. Make sure the surface is flat
and even.
•In the case of a vertical motor axis, the respective lower condensation drain hole
must be open.
•Fasten the fan connecting cable using cable ties to the guard grille or motor
braces.
A minimum head gap “A” of 2.5 mm in all installation
positions but especially in installation position H (hor-
izontal motor shaft) is necessary. Distortion due to
uneven surface may lead to fan failure due to brush-
ing against the fan wheel.
