4.7 Assembly of the MAXvent fan
Attention!
•
Motor and accessories (protective grille etc.) must be connected to earth.
•
Connection points must be reliably protected against the formation of corrosion.
Observe the following points for all types of fans:
•
Do not install without suitable supports/brackets.
•
Ensure adequate clearance on suction and pressure sides. When installing fans in
devices, ensure there is a suitable inlet opening through a minimum integration
distance, which corresponds to the rough diameter of a fan.
•
Warping caused by the elasticity of the components must not cause the impeller to
rub against the tubular housing.
•
Ensure that there is a constant gap dimension "a" (see figure below) betweenimpeller
and tubular housing.
•
According to EN 14986, the minimum distance between non-moving and moving
parts must be complied with. The distance must not be less than 0.5 % of the
diameter (at least 2 mm and at most 20 mm).
Minimum gap dimension:

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.
•
A second person must always be present when working on energized parts or lines
who disconnects in case of emergency.
•
Do not use metal compression-gland fittings with plastic terminal boxes. - Danger of
an electric shock if connection is not made correctly!
•
Electrical equipment must be checked regularly: Loose connections are to be retightened and damaged cables must be replaced immediately.
Assembly instructions MAXvent Electrical installation
L-BAL-F076-GB 1747 Index 001 Part.-No. 00705156-GB
20/36
5.2 Connection
Attention!
The electrical connection must be done according to the motor operating instructions and
according to EN 60079-14: "Explosive areas - Part 14: Project planning, selection and
installation of electrical systems."
Observe the following points:
" It must be strictly observed that the line voltage complies with specified on the rating
plate and lies within the allowable tolerance specifications (
technical data).
" Observe the connection values in the motor operating instructions.
" Observe the tightening torques in the motor operating instructions.
" When using an external terminal box, the operating instructions must be taken into
account.
" The protective devices of the motor must be connected!
" Check all components for continuity.
" Only use suitable threaded gland bushings for your ATEX Zone.
" Before start-up of the installation, check the direction of rotation of the impeller:
Airflow direction "V"
Airflow direction "A"
" If the fan was only delivered with one cable, but without external terminal box, the
electrical connection must be carried out as follows:
9-core cable
or
6-core cable
Assembly instructions MAXvent Electrical installation
L-BAL-F076-GB 1747 Index 001 Part.-No. 00705156-GB
21/36
5.3 EMC-compatible installation
Interference emission and installation of cables
•
In order to prevent faults attributable to interference and to ensure compliance with
the radio interference level, the connecting leads must be kept as short as possible
both in the motor terminal box as well as in the controller. Spacing between supply
cables, motor cable and signal cable should thereby be kept as large as possible.
•
When laying shielded lines, never use so-called "pigtails" on shields (twisting of the
shielding braid into strands).
•
EMC screwed connections must be used on cable entries.
•
High-frequency earthing of the complete drive system must be carried out on both
sides on the motor and the inverter in a technically correct manner. Implement a
contacting process on a large-scale for good discharge of high-frequency currents for
a 360° contacting process by means of EMC shield clips on the inverter and an EMC
screwed connection on the motor.
•
Make sure that the cable gland has an electro-conductive connection to the
terminal box. (If necessary, the available coating must be removed on the
contact point or a tooth lock washer used on the counter ring).
•
Maintenance or emergency switches installed between inverter and motor must
also be shielded.
•
Please observe the corresponding installation instructions of the frequency
inverter that is used!
Reducing bearing currents when operating on the inverter
•
When operating on the inverter harmful bearing currents can occur in the motor. This
depends on many factors which, in many cases, ZIEHL-ABEGG cannot influence.
Thus, it comes down to the expert installation in the respective assembly situation.
The following points serve as a guideline, but cannot always prevent bearing currents
from occurring.
•
To systematically reduce and prevent damage by bearing currents, you must take into
account the overall system made up of motor and inverter. But further additional
measures may be necessary, e.g. use of all-pole sinusoidal filters or use of hybrid
bearings.
•
The ZIEHL-ABEGG Fcontrol frequency inverter is already geared to
ZIEHL-ABEGG motors and possesses an all-pole sinusoidal filter so that no
harmful bearing currents at all can be expected with the correct installation.
Frequency inverter, external brand
The following measures support the reduction of harmful bearing currents:
•
The specified measures with regard to EMC-compatible installation must be observed
and implemented.
•
For electrical bridging of vibration dampers, use high-frequency equipotential bonding
conductors made of braided flat copper strips with a minimum cross-section of
16mm².
•
Design the contacting process on a large-scale.
•
Use shielded connecting cables with as symmetrical a design as possible.
•
Connect the screen on both sides on the motor and inverter.
Assembly instructions MAXvent Electrical installation
L-BAL-F076-GB 1747 Index 001 Part.-No. 00705156-GB
22/36
•
If the cable shield cannot be contacted or not contacted sufficiently due to special
framework conditions, use a separate high-frequency equipotential bonding conductor between the motor housing and the protective earth bar of the inverter.
– Install the separate high-frequency equipotential bonding conductor using braided
flat copper strips or high-frequency stranded conductors. Solid copper lines are not
suitable for high-frequency earthing due to the current displacement effect.
•
Use suitable common mode filters at the inverter output.
•
Limit the voltage increase by using suitable output filters (du/dt filters).
•
We recommend the use of all-pole sinusoidal filters.
•
When using all-pole sinusoidal filters, screened motor leads, metal terminal boxes
and a second earth connection to the motor can be omitted.
•
General recommendation: Continuous operation of the fan / motor below 15%
of the nominal speed is not economically and technically reasonable.
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.
6.2 Check before commissioning
Observe the following points before the initial start-up:
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. Have all objects (tools, etc.) been removed from the air flow?
4. That safety devices -if necessary- are mounted (EN ISO 13857)?
5. The impeller is out of reach?
6. Are the condensation water drains holes (as far as available) open or respectively
closed according to the suitable installation position?
7. The impeller must not rub against the tubular housing. The gap dimension must at
least correspond to the gap dimension according to EN 14986 (checking of the gap
dimension at the periphery).
8. Continuous potential equalisation must exist.
9. The threaded gland bushings are tightened.
10. The tubular housing flap (if available) is correctly closed and screwed together.
11. Connection data complies with the specifications on the rating plate?
12. Is the overheating protection equipment of the motor properly connected?
Assembly instructions MAXvent Start-up
L-BAL-F076-GB 1747 Index 001 Part.-No. 00705156-GB
23/36
Start-up may only begin when all safety instructions have been verified and any
hazards have been ruled out.
•
Check whether the direction of rotation of the impeller corresponds to the arrow
attached to the tubular housing.
•
Motors with a rated output greater than or equal to 4 kW are generally connected via
a "star-delta starting switch".
•
If the fans were stored for a longer period or were not in operation, the insulation
resistance of the motor winding must be measured before start-up. In the case of
values below 1.5 MΩ the windings must be dried.
6.3 During start-up check the following
Observe the following points during start-up:
1. Check the direction of rotation (
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. A-rated sound power levels of over 80 dB(A) are possible, see product catalogue.
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.
7 Trouble shooting
7.1 Code of behaviour in the event of faults
" In the event of faults, which represent a danger to people, installation or environment,

8 Service work
8.1 Repairs / maintenance
Attention!
•
For safety reasons, changes to the fan may only be carried out after receipt of written
approval from ZIEHL-ABEGG. Unapproved changes can lead to risk of injury!
•
The equipment in explosion-proof version must neither be opened nor repaired.
Bearing changes are also not permitted by the customer or normal service technician.
•
ZIEHL-ABEGG ATEX fans/motors are partially or completely equipped with antistatic,
conductive painting or coating. Repainting can lead to dangerous, static charges and
is therefore not permissible!
•
After removal of the motor and/or impeller, the fan must be balanced again! To do so,
please contact your manufacturer.
•
In the case of complete dismantling and reinstallation of the fan, checking must be
carried out before start-up (see start-up).
•
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 shoes and gloves for 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.
•
Keep the fan airways free. There is the danger of foreign bodies being sucked in and
objects flying out!
•
Watch out for vibration free motion!
•
The impeller is subject to natural wear depending on the area of application and the
conveying medium. Regularly check that no deposits have formed on the impeller
which can lead to an imbalance and thus damage (see Chapter: Cleaning).
•
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 fins and in recesses on the stator –
can lead to reduced cooling and the motor switching off prematurely. For this reason,
remove deposits in good time (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.
Assembly instructions MAXvent Service work
L-BAL-F076-GB 1747 Index 001 Part.-No. 00705156-GB
27/36
•
Repair, e.g. by welding is prohibited!
•
Bolted-on wheels 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.
•
Compliance with the minimum head gap must be checked at least once a year.
Depending on the application this interval can also be shorter.
•
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.
•
Regularly check the earth connection of all components.
Information
Confirmation number for inquiries or in service cases see rating plate.
8.2 Cleaning
To avoid risks of imbalance, the impeller must be checked and cleaned regularly. The
impeller must be cleaned and dusted at least once a year. Depending on the place of
use, this interval can also be shorter to exclude all risks of imbalance.
Information
For fans operated in Zone 21 and 22 (dust), special requirements for careful cleaning
apply.
Danger due to electric current
Voltage supply for motor must be interrupted and secured against restoration!
Observe the following points:
•
Clean the fans`s flow area.
•
Keep the fan airways free. There is the danger of foreign bodies being sucked in and
objects flying out!
•
Do not use any aggressive, paint solvent cleaning agents when cleaning.
•
Make sure that no water gets into the inside of the motor, note protection class (IP).
•
The condensation bores (if available) corresponding to the installation position must
be checked for free passage.
•
In case of improper cleaning work, no warranty is assumed regarding corrosion
formation / paint adhesion for unpainted / painted fans.
•
To avoid accumulation of moisture in the motor, the fan must be operated for at least 1
hour at 80% to 100 % of the maximum speed before the cleaning process!
•
After the cleaning process, the fan must be operated for at least 2 hours at 80 to
100 % of the maximum speed for drying purposes!
