2 Safety
2.1 Safety instructions
This chapter contains instructions to prevent personal injury and property damage.
These instructions do not lay claim to completeness. In case of questions and problems,
please consult our company technicians.
Attention!
•Non-compliance with the information and safety instructions listed in these assembly
instructions can cause serious health and safety risks!
•It is essential to observe the notes in the motor manufacturer’s assembly instructions,
which are part of the scope of supply.
Assembly instructions MAXvent Safety
L-BAL-F054-GB 2018 Index 005 Part.-No. 00501414-GB
5/32

Be aware of the following Points:
•Assembly and electrical connection may only be carried out by skilled personnel in
compliance of applicable standards and these assembly instructions.
•Only operate the fan according to the intended application, and only up to the
maximum permissible speed given in the information on the fan/impeller rating
plate. See operation speed at 50 Hz (50 Hz motors) or 60 Hz (60 Hz motors). Exceed-
ing the maximum permissible speed leads, as a result of the high kinetic energy, to a
hazard situation. The impeller can disintegrate - lethal hazard!
•In case of speed control through a frequency converter, it must be ensured that the
max. permissible speed cannot be exceeded due to any frequency converter malfunc-
tion.
•In a fan system consisting of a motor, frequency inverter and impeller, impermissibly
high vibrations can occur in narrowly limited speed ranges. Continuous duty is not
permissible under these conditions. The impeller could burst - danger of death!
•The conveyance of solid matter or solids content in the conveying medium is not
permissible and can lead to dangerous situations. ZIEHL-ABEGG rejects any liability
for damage of any kind as a result of such use.
•If the operating voltage differs, the current may change disproportionately. This must
be taken into account when a selecting possible frequency inverter and the mains
side fuse protection.
•The fans must be operated in the temperature ranges specified on the rating plate.
•In order to approve its fans with standard motors, ZIEHL-ABEGG carries out exten-
sive qualification tests. Depending on the installation conditions and the other system
components in use (e.g. frequency inverter incl. parameter configuration), in individual
cases there may be unusual noises and vibrations (resonance) caused by the elec-
trics.
•If the impeller is accessible, guard grilles must be installed according to EN 13857.
These must not be changed and must be adequately secured. The appropriate
specified screw size and quality must be used.
•Objects which can fall onto the fan from a greater height must not be allowed to enter
the impeller.
–Since a residual risk due to falling objects, incorrect behaviour, etc. cannot be
completely ruled out, the designer, operator or manufacturer of the installation or
system in which the fan is to be installed, must prevent any potentially hazardous
situation from arising by means of appropriate safety measures in line with stand-
ard EN ISO 12100.
•The operator is responsible for maintenance of the fan.
•Compliance with the EMC Directive only exists if the fan is directly connected to the
main power supply. If the fan is installed in a system or combined with other products,
the system manufacturer is responsible for compliance with the EMC Directive.
•The owner or operator must ensure that the equipment (fan and electrical system) is
used according to the description in these instructions and kept in good operating
condition.
•The user shall only put the fan into operation after it has been properly installed.
•The fan must be operated in accordance with the assembly instructions.
•To ensure operability, safety devices (especially the overheating protection equip-
ment) must be checked regularly.
Assembly instructions MAXvent Safety

•The instructions for installation and use must be complete and available to users at
any time.
•No safety and warning instructions on the fan may be removed, and the user must
make sure that they are legible.
•The persons responsible for the installation, start-up, operation and maintenance of
the device must be competent and possess sufficient experience to correctly perform
their work.
•In addition, they must know the European standards and guidelines (at national and
regional level and if applicable the in-house regulations) for safety and hazard
prevention. A new user may only work under the supervision of an experienced
operator.
•This device must not be used by persons with limited physical and mental abilities.
Moreover, the minimum legal age must be observed, the users must be adequately
trained.
2.2 Intended use
Attention!
•The fans are only intended for the conveyance of air or mixtures similar to air.
•Any other use above and beyond this is considered not for the intended purpose
unless agreed otherwise by contract. The manufacturer will not be liable for any
damage resulting from this. The individual or company using it bears the sole risk.

•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 fan should be lifted out
of the package by two persons (according to REFA). The values may differ from
country to country.
4.3 Connection lead & terminal box
Be aware of the following Points:
•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.
•Fasten the motor connection cable with cable tie to the motor suspension or guide it
directly through the housing and fasten to the motor suspension as required.
4.4 Assembly in a humid atmosphere
Information
If the device is not in use for longer periods in a humid atmosphere, it is recommended to
operate the motor/fan for at least two hours every month at 80 - 100 % of maximum
speed to remove any moisture that has penetrated inside.
If available, the stationary heaters must be turned on when the motor is not running.
4.5 Assembly of MAXvent fans type FV, DN
For attachment to fixed motor flange use screws with property class 8.8 or A2-70
(stainless steel) to EN ISO 4014 and provide with suitable screw locking.

When using screws with different friction values or strength classes, different tightening
torques may be necessary.
Pay attention to the following installation situations:
•In horizontal installation position ensure that the motor suspension is aligned as
shown in Figure 1.
•Installation of design K and F with mounting feet is possible upon request.

Observe the following points for all types of fans:
•Do not install without suitable supports/brackets.
•Install the fan housing when de-energized. A deformation due to an even support can
lead to fan failure caused by impeller contact.
•Ensure an even head gap between impeller and housing.
•Fasten the fan with suitable bolts using all the fastening points of the flanges.
•Fasten the accessories with suitable bolts.

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 Connection
Attention!
The electrical connection must be carried out according to the motor operating
instructions.
Be aware of the following Points:
"It must be strictly observed that the supply voltage complies with specified on the
rating plate and lies within the allowable tolerance specifications (see 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.
"Before start-up of the installation, check the direction of rotation of the impeller.

5.3 Frequency inverter and EMC
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.
