If any problem is noticed upon reception, immediately contact the transport com-
pany and/or CIRCUTOR's after-sales service.
1.2.- TRANSPORT AND HANDLING
The transport, loading and unloading and handling of the device must be carried
out with proper precautions and using the proper manual and mechanical tools so
as not to damage it.
If the device is not to be immediately installed, it must be stored at a location with
a firm and level floor, and the storage conditions listed in the technical features
section must be observed. In this case, it is recommended that the device be stored
with its original protective packaging.
To move the device a short distance, the device’s floor support profiles facilitate handling with a pallet
jack or forklift. (Figure 1)
Figure 1: Transport with pallet jack.
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

AFQm IP54
Instruction Manual
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.
Figure 2: Unloading with a forklift.
When unpacking the device, pay attention to prevent damaging the device if you are using cutting
tools, such as cutters, scissors or knives.

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.

12
AFQm IP54
Instruction Manual
3.2.- INSTALLATION LOCATION
The device must be installed in an environment where the temperature outside the cabinet is between
-10ºC and 50ºC, 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 IP54 in an environment protected from flammable liquids, gases and
corrosive substances and, whenever possible, water and dust.
Make sure there are no power factor correction devices installed in the same mains as
the AFQm IP54.
If there are any compensation devices, these must be detuned in order to avoid inter-
ference between them and the AFQm IP54.
3.2.1.- VENTILATION REQUIREMENTS
Section “4.6 - THERMAL PROTECTION” describes all the thermal protections available in the device.
The AFQm IP54 uses a cooling system with an air inlet at the front and an air outlet at the rear of the
unit. Be sure to leave a gap at the back of the cabinet of at least 150 mm. To ensure this, the device
includes spacers at the rear that act as a bumper.
Table 4: Ventilation distances: AFQm IP54.
Ventilation distances: AFQm IP54
150 mm
The IP54 rating means that the device is protected against dust ingress and splashing water from any
direction. However, it is important to keep in mind that excessive dust in the environment will saturate
the filters, which will reduce the performance of the device.
In cold conditions, when frost appears on the surface, it is necessary to wait for it to disappear before
opening the door, to avoid damaging the protective seals.

13
Instruction Manual
AFQm IP54
3.3.- STORAGE FOR LONG PERIODS
If the device is not installed after receipt, the following recommendations must be observed to keep
the device in a good state:
Keep the device in a dry atmosphere and at a temperature of between -20ºC and 50ºC.
Avoid exposure to direct sunlight.
Keep the device in its original packaging.
If the active filter is stored for a long time disconnected from the mains, a specific process must be
applied to restore the internal dielectric layers of the DC bus capacitors. Table 5 shows the recommen-
dations for starting the device, according to the length of its storage period.
Table 5: Start-up process, according to storage time.
Storage time Process
< 1 year No special treatment required.
> 1 year
Connect the AFQm IP54 to the mains at least one hour be-
fore starting up the device. Power the device and leave it in
STOP mode
3.4.- INSTALLATION
The Cabinet-type AFQm IP54 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.

14
AFQm IP54
Instruction Manual
3.5.- CONNECTION
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 70A or 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 recom-
mended 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 IP54 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.
The correct connection of the current transformers is vital for the AFQm IP54 filters to
operate properly. If the phases L1, L2 and L3 are switched in the secondary, the filter
will not work properly.
The AFQm IP54 devices have built-in fuse overcurrent protection.
Install external protection according to the type of installation, the facility’s maximum
short-circuit current, the maximum fuse current, and the regulations in force at the
place of installation.
If local regulations require the use of earth leakage protection devices, only DC sensitive
RCD (RCD type B) should be used with AFQm IP54. Active filters work internally with
DC currents, and, in case of failure, the DC currents may produce malfunction on type
A RCD devices.
Ensure that the installation of the device in your electric distribution system (TN, VT, IT)
complies with current standards.

15
Instruction Manual
AFQm IP54
Check that there is a neutral in the place where three-phase active filter connections are made with
neutral, AFQm-4WF-xxxx.
The active filter must be of the correct size for the harmonic currents it has to filter and to comply with
the installation’s electrical features.
Check section “4.3.- RATED CURRENT DIMENSIONS” to define the correct dimensions of
the device.
Failing to observe the recommendations described in this section might cause the ac-
tive filter to work incorrectly and prevent proper compensation of the installation's
current harmonics.
Do not install various filters in series one after another in the same installation, con-
figured to correct the same disturbances. This can produce an overcompensation of
the disturbances, which could cause instability in the mains (Figure 4)
Figure 4: Do not install various active filters in series.
3.6.- DEVICE TERMINALS
The connections on the AFQm IP54 are located at the bottom of the cabinet.The lower windows on the
cabinet have to be used to route the cables into the device, Figure 5.
If dust can enter the device from the bottom, these windows will have to be machined and suitable
cable glands installed for the cables.
Figure 5: Sliding windows for the connection wiring.
You should never remove the cover closest to the front part.
