1.1.- RECEPTION PROTOCOL
• Make sure that the unit has not been damaged during transport.
• Check that the unit received matches that described in your order and
that its electrical features are suitable for the mains where it is to be
connected. See features label on the rear of the door.
(Figure 1)
Figure 1: Features label of the AFQ-4W
• Make sure that it is equipped with the following accessories:
- Main switch handle.
- 2 keys for locking the door.
- Manual.
The AFQ-4W-25 also has:
- 4 DIN 580-M8 suspension eye bolts (male).
- 4 DIN 963, M8x16 screws.
• Check the shipping documentation. The dispatch note number must
coincide with the number marked on the outer part of the unit. Unload and
transport the unit following the instructions in section 1.2.- TRANSPORT

packaging.
To move the unit a short distance, the unit's floor support profiles facilitate
handling with a pallet jack or forklift. (Figure 2)
The centre of gravity of some units may be found at a considerable
height. Therefore, when handling with a forklift, it is recommended
that the unit be securely fastened and that no abrupt operations are
made. The unit should not be lifted more than 20 cm off the ground.
Figure 2: Transport with pallet jack
When unloading and moving the unit, 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. The cabinet must be raised by placing the forks underneath
the profile that supports the unit. (Figure 3).
Instruction Manual 9
AFQ-4W
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 in
equipment. The necessary precautions must be taken to prevent the
equipment from tipping over during abrupt operations.
Figure 3: Unloading with a forklift
1.3.- STORAGE
The unit should be stored according to the following recommendations:
• Avoid placing it on uneven surfaces.
• Do not store in outdoor areas, humid areas or areas exposed to the
splashing of water.
• Avoid hot spots (maximum environmental temperature: 45ºC)
• Avoid saline and corrosive environments.
• Avoid storing the unit in areas where a lot of dust is generated or where
the risk of contamination by chemical agents or other types of pollution is
present.
• Do not place any weight on top of the unit's cabinets.

Table 2: Start-up process depending on storage time.
3.4.- SIZING THE NOMINAL CURRENT OF THE AFQ-4W
The purchased active filter must be sized for the harmonic currents it has to filter.
The nominal current of the AFQ-4W must be at least 20% higher than the
maximum level of harmonics to be filtered. This factor may be higher depending
on the installation features.
The active filters can suffer from overloading when trying to cancel the harmonic
currents in high-impedance, short-circuit mains. The clearest symptom for
detecting such cases is that they originally start from a THD(V) (under voltage)
of over 3%. It has been seen that the higher the initial THD(V), the greater the
chance of filter overload.
The reason for this behaviour is that the load does not behave as a current
source, but rather the larger the harmonic current absorbed by the filter the more
harmonics are produced by the load, which can produce up to more than double
what was initially measured.
To avoid this phenomenon, it is best to oversize the active filter by multiplying the
initial current of harmonics measured in the load by a safety factor (SFh). In
other words:
I
(AFQ) = [SFh · I

Where:

To calculate this safety factor you must first know the parameter called shortcircuit ratio RSC at the connection point of the PCL transducers (not on the
installation input). The short -circuit ratio is defined as the ratio between the shortcircuit current of a mains (ISC) and the nominal current of the set of non-linear
transducers (I
) producing the harmonics to be filtered. (Equation 2)

An incorrect configuration may significantly affect the performance of
personnel to select
3.8.1.2.- PARALLEL MODULE CONFIGURATION
Configure the number of units in parallel in the PARALLEL MODULES
parameter (Figure 22). If there is a single unit in parallel, leave the default value
(1).
3.8.1.3.- WORK MODE CONFIGURATION
In order to configure the work mode, return to the home screen, press START
and access the work mode configuration screen.
Start the harmonic filtering, phase balancing and/or reactive compensation
functions depending on the needs of the installation (Figure 23). (For further
information on all of the functi ons, refer to section 4.3.- CONFIGURATION )
Figure 23: Configuration of the functions of the AFQ-4W.
the AFQ-4W. Consult the technician or qualified
the unit configuration, depending on the needs of the installation.

3.8.2- UNIT VERIFICATION
3.8.2.1.- VERIFICATION O F THE MAINS VOLTAGE AND FREQUENCY
The voltage and current screen (Figure 24) can be accessed from the home
screen by pressing on VIEW:
Figure 24: Verify mains voltages, currents and frequency.
Make sure the mains voltage measurements correspond to the real
voltages of the installation.
Make sure the frequency measured by the AFQ-4W is the real frequency
of the installation.
Make sure the load current measurements correspond to the installation
current levels.

AFQ-4W
3.8.2.2.- VERIFICATION OF THE ACTIVE AND REACTIVE POWER
The load power screen (Figure 25) can be accessed from the home screen by
pressing VIEW:
Figure 25: Verify active and reactive power and load power factor readings.
Make sure the active power measurement of the load equals the power
levels of the installation.
Make sure the reactive power measurement of the mains equals the
reactive power levels of the installation.
Check the power fact or in the three phases. If there are phases with very
high reactive power and very low active power levels, this might indicate
an error in the phase order. In this case, check the connections of the
three-phase mains power supply cables with neutral and the load current
reading cables, as described in sections 3.5.1 and 3.5.2.
