The centre of gravity of some devices may be found at a considerable height.There-
fore, when handling with a forklift, it is recommended that the device be securely
fastened and that no abrupt manoeuvres made. The device should not be lifted
more than 20 cm off the ground
When unloading and moving the device, use a forklift with forks long enough to support the entire
length of the base. Otherwise, the forks should be long enough to support at least ¾ of said depth.The
forks must be flat and supported firmly by the base. Raise the device by placing the forks underneath
the profile that supports the device. (Figure 2).
There might be an offset in the centre of gravity from the centre of the cabinet,
as a result of the uneven distribution of loads inside the device. The necessary
precautions must be taken to prevent the device from tipping over during abrupt
operations.

3.- DEVICE INSTALLATION
3.1.- PRELIMINARY RECOMMENDATIONS
The device installation and the maintenance operations must only be carried out by
authorised and qualified personnel.
In order to use the device safely, it is critical that individuals who handle it follow the
safety measures set out in the standards of the country where it is being used, use the
personal protective equipment necessary (rubber gloves, face protection and approved
flame-resistant clothing) to prevent injuries due to electric shock or electric arc due
to exposure to current-carrying conductors and pay attention to the various warnings
indicated in this instruction manual.
Incorrect installation or configuration of the device could cause serious damage to the
device itself and to other devices of the installation.
Only suitable for assembly on concrete or other non-combustible surfaces, and in re-
stricted access areas.
The devices are not intended for use in life support, medical safety equipment or similar
applications, whereby a fault in the device could cause loss of life or physical injury.
They are neither intended for military or defence applications. They should be installed
in areas with restricted access.
Disconnect the main switch before starting any maintenance task on the active fil-
ters.
Make sure the device is properly earthed before powering up. Any fault in the earth
connection might cause a risk of electrocution to the user and damage to the device
itself in the case of lightning or other transients.
Before handling the current transformers, ensure that the secondary is short-circuited.
Never open a current transformer secondary under load.

Instruction Manual
AFQm
3.2.- INSTALLATION LOCATION
The device must be installed in an environment where the temperature outside the cabinet is between
-10ºC and 45ºC, with a maximum humidity of 95% without condensation.
Do not install the device close to a hot spot and keep it out of direct sunlight.
Install the AFQm in a place protected from water, dust, flammable liquids, gases and
corrosive substances.
Make sure there are no power factor correction devices installed in the same mains as
the AFQm.
If there are any compensation devices, these must be detuned in order to avoid inter-
ference between them and the AFQm.
3.2.1.- VENTILATION REQUIREMENTS
Section “4.6 - THERMAL PROTECTION” describes all the thermal protections available in the device.
3.2.1.1.- Wall-type AFQm
The device has a power control system that controls the rotation speed of the fans and the maximum
power of the device according to the internal temperature, to ensure the best performance in any
condition.
Table 8: Ventilation distances: Wall-type AFQm.
Ventilation distances : Wall-type AFQm
50 mm 400 mm
3.2.1.2.- Rack-type AFQm
The Rack-type AFQm uses a forced ventilation cooling system, with an air inlet on the front panel and
an air outlet at the back of the device.
Once installed, the device’s flows of inlet air and outlet air must be allowed to circulate freely. At max-
imum power, the Rack-type AFQm circulates an airflow of 375 m3/h.
The device has a power control system that controls the rotation speed of the fans and the maximum
power of the device according to the internal temperature, to ensure the best performance in any
condition.
To maintain the device’s performance, we recommend ensuring that the air circulates freely through
the front panel of the Rack-type AFQm, and that the rear is free of obstacles, with a gap of at least
300 mm.

16
AFQm
Instruction Manual
It should be noted that, depending on the installation conditions in the cabinet and in the room where
this is placed, the outflows of hot air may be sucked back in by the device’s fans, causing a feedback
of hot air that will lower the performance of the device.
It is also necessary to bear in mind the power dissipated by the device when choosing where to install
it, to ensure proper air recirculation, to make sure that the intake air is a suitable temperature. See
“11. TECHNICAL FEATURES”.
Table 9: Ventilation distances: Rack-type AFQm.

3.2.1.3.- Cabinet-type AFQm
The cabinet-type AFQm uses a forced ventilation cooling system, with an air inlet on the front panel
and an air outlet at the back of the device.
The ventilation grille at the top must not be blocked, leaving enough space to the ceiling to allow the
heat to dissipate. The distance depends on the characteristics of the installation site.
There is no need to leave space between the sides or at the back of the cabinet; they can be installed
next to other cabinets and against a wall.

The Wall-type AFQm has a number of holes on the top and bottom of the device, Figure 4,to facilitate
transport and installation of the device.
These holes can be used as attachment points for external manipulation tools, or a bar (not included)
can be passed through them to improve transport and installation of the device.
Figure 4: Holes to facilitate transport and installation.
The device must be fixed vertically to a wall or support.
Use 4 fixing screws with a diameter of 8 mm, suitable for the chosen wall or support.

The ventilation grilles must not obstructed or covered at any time.
3.4.2.- RACKTYPE AFQm
The Rack-type AFQm should be installed in a 19” rack cabinet.
The height of the device is equivalent to 9U. (U is the rack unit, 1U = 4.445 cm)
You can install more than one AFQm in a single cabinet.
Follow these steps to install it inside the cabinet:
1.- Extend the rack cabinet’s anti-tip feet.
Unless the rack cabinet is secured to the floor, the anti-tip feet have to be extended and
fixed to the floor, to ensure maximum safety during the assembly process.
2.- Open or remove the door at the front of the cabinet.
3.- Place the AFQm on the cabinet’s rails or shelves. Make sure that they are suitable for the weight of
the device; use cross braces if necessary.
Do not use front handles to carry the module.

Fit the device with the help of another person.
4.- Fasten the device to the points provided for this purpose. Use 4M6 fixing screws.
3.4.3.- CABINETTYPE AFQm
The Cabinet-type AFQm models are free-standing cabinets with 4 bearing supports on the floor.
The mounting surface must be solid, support the device’s weight and be level.
The cabinet must never be welded to the floor using arc welding, as this may destroy
the electronic components.
The device’s top panel is part of the ventilation system. The top panel is inverted to make it easier to
transport.
It must be placed in the correct position to enable the device to operate properly. To do this:
1.- Remove the transport rings.
2.- Remove the top panel from the top of the cabinet.
3.- Rotate the top panel. The non-slotted part goes at the front of the cabinet.
4.- Install the transport rings with rubber washers supplied.

3.5.- CONNECTION
Wall and Rack type AFQm models:
Use cables of a cross-section suitable for the rated current of the filter and that comply
with the standards of the country in which they are being installed.
The earth conductor must have at least the same cross-section as the phase conduc-
tors. If the phase conductors exceed 16 mm2, the earth conductor will be at least 16
mm2. If the phase conductors exceed 32 mm2, the earth conductor can be the half of the
cross-section of the phase conductors
For 100A models (AFQm-xxx-100M and AFQm-xxx-100R), under certain circumstanc-
es, the contact current may exceed 3.5 mA ~.
The recommended minimum cross-sections are (1):
AFQm-xxx-030M : 16 mm2
AFQm-xxx-060M : 25 mm2
AFQm-xxx-100R and AFQm-xxx-100M : 50 mm2
Neutral conductor cross-section must suit the expected neutral current and must be
selected according to the external protection devices.
Cabinet type AFQm models:
For the cabinet’s power supply, a cable with a cross-section suitable for the maximum
current that can flow through the device must be used. Although the device is com-
posed of 100 A modules, to make installation easier, the modules are already wired, and
the user only has to take into account the device’s total capacity. The recommended
minimum cross-sections are (1):
AFQm-xxx-070C: 35 mm2
AFQm-xxx-100C: 50 mm2
AFQm-xxx-140C: 70 mm2
AFQm-xxx-200C: 95 mm2
AFQm-xxx-210C: 120 mm2
AFQm-xxx-300C:150 mm2
AFQm-xxx-280C: 150 mm2
AFQm-xxx-400C: 240 mm2
Neutral conductor cross-section must suit the expected neutral current and must be
selected according to the external protection devices.
(1) These sections are for informative purposes only. The conductor cross-section must be selected according to the current,
prevailing regulations, cable type and type of wiring installation.
Ensure that the AFQm is earthed correctly to prevent the risk of electric shock.
To measure the current, class 0.2S transformers of the TC or TCH series are recom-
mended.
The use of transformers with ratios close to the current to be measured is recommend-
ed.
