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 lines or cables must be replaced immediately.
5.2 Mains connection
Attention!
The fan is intended for the installation as part of a ventilation system and has no work
place from which it is operated. Therefore it does not have a “command device for safe
shutdown” according to EU Directive 2006/42/EG (“Machinery Directive”) Article 1.2.4.
Such a device must be installed by the system owner.
Danger due to electric current
The mains voltage must match the specification on the rating plate and be within the
permissible tolerance specifications (see Technical data).
Fastening connecting cable
•Fans version “F...”
"Fix the fan connecting cable to the screen protection against accidental touching
with cable ties or similar.
•Fans version “Z...”
"Lay connecting cable in the cable duct.
5.2.1 Mains connection for 1 ~ types

5.2.2 Mains connection for 1 ~ types
Mains connection to: PE, L1, L2 and L3.
"Open terminal box.
"Connection to devices for speed control (e.g. frequency converter, phase control):
Connect the motor as described in the control unit operating instructions.
"Remove cable. Electrical connection according to circuit diagram in the terminal box
"The temperature monitors (TB) or thermistors (TP) built into the winding serve as the
motor protection and must be connected!
"Without thermal protection: Use a motor protection switch!
"Only use the included cable glands.
"Use filler plug seal for the cable glands also.
"Screw on plastic terminal box covers should be sealed with sealant.
"Starting torque for screw on covers, Plastic version 1.3 Nm, Metal version 2.6 Nm.
5.2.3 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!
5.3 Motor protection
1 ~ motors: Motor protection by internally wired thermostat switch.
Thermal contacts switch after triggering due to excess temperature and independently
close after cooling-off. The fan can then start up.
If the mains voltage is permanently above 240 V in fan motors for 1 ~ 230 V +/-10 %, the
temperature monitor might also respond.
3 ~ motors: The temperature monitors (TB thermostats or TP thermistors) built into
the winding serve as the motor protection and must be connected!
Protection of several motors using one protection device is possible by connecting the
temperature monitors of the individual motors in series. It must be remembered that, if a
temperature fault occurs at one motor, all motors will then be switched off. In practice,
motors are therefore assembled in groups so that emergency operation with reduced
performance is still possible if a motor fails.
Information
•It is recommended that a separate motor protection unit be foreseen for each fan.
•For motors with thermistors “TP” (PTC thermistor) e.g. type U-EK230E
•For motors with thermostats “TB” (thermal contacts) e. g. type STDT16 or AWE-SK
(see Enclosure: Connection suggestion: 3 ~ motors with motor protection unit type
STDT.)

5.4 Speed control
Information
We cannot guarantee that competitive brands of voltage control devices and frequency
converters when used for rotational-speed control of our ventilators will function properly
and not damage the motor.
The EMC guideline is to be observed in connection with our control units. If the fans are
completed with components of other manufacturers, the operator is responsible for
keeping to the EMC guideline 2014/30/EU.
5.4.1 Electronic voltage controllers (phase cutting)
•When controlling ventilators using electronic voltage regulators, motor noise can
occur (due to the system), which can be troublesome.
•On fast running ventilators with a high level of air noise, this noise is relatively low. On
slow running ventilators with a low level of air noise, this noise may be dominant in
the lower speed range due to the occurrence of resonance.
For systems where noise is critical, we recommend using our Fcontrol series frequency
converters with integrated sinusoidal filter.
5.4.2 Frequency inverter
•ZIEHL-ABEGG axial fans are suitable for operation with frequency inverters if the
following points are complied with:
–Between the inverter and the motor, sinusoidal filters should be incorporated which
are effective for all phases (sinusoidal output voltage, phase against phase, phase
against protective conductor) as offered by manufacturers. Please ask for our
technical information L-TI-0510.
–du/dt filters (also called motor or suppression filters) cannot be used in place of
sinusoidal filters.
–When using sinusoidal filters, screened motor leads, metal terminal boxes and
a second earth connection to the motor can, if necessary, be omitted. Check-back

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. That safety devices -if necessary- are mounted (EN ISO 13857)?
4. The impeller is out of reach?
5. Are the condensation water drains 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 rotat. direction (see the rotat. direction arrow on the fan blade, impeller
base plate or intake-side support 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. 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/im-
peller 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.
•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!
•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).
•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!
•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.
•Please consult our service department with regard to changing the bearing as for all
other damage (e.g. to the coil).
•Regular inspection, if necessary with cleaning, is necessary to prevent imbalance 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.
•The screen protection against accidental contact must be fixed again properly
at the end of the work and before restarting!

Life expectancy capacity
approx. 30,000 h per DIN EN 60252
dB(A) values see product catalog
Ball-bearings service life The according to standard calculation methods determined bearing serv-
ice life expectation of the motor-integrated ball bearings is mainly deter-
mined by the grease service life F10h and amounts for standard applica-
tion to approx. 30.000 - 40.000 operating hours. The fan or motor is
maintenance-free due to the use of ball bearings with "lifetime lubrica-
tion". Once the grease operating life F10h has been reached, it may be
necessary to replace the bearing. The bearing service life expectation
may change compared to the specified value, if operating conditions
such as increased vibrations or shocks, increased or too low temper-
atures, humidity, dirt in the ball bearing or unfavourable control modes
are present. A service life calculation for special applications can be
provided on request.
