CIRCUTOR AFQ Series - Manual (Page 17)

AFQ-4W
Instruction Manual 17
Never power or start up the active filter with the front door open or
the side or rear covers removed.
Check that there is a neutral in the place where three-phase active filter
connections are made with neutral, AFQ-4W.
The active filter must be of the correct size for the harmonic currents it has to
filter and for the installation's electrical features.
Check the section 3.4.- SIZING THE NOMINAL CURRENT OF THE
AFQ-4W to define the correct unit size. Failing to observe the
recommendations described in this section might cause the active
filter to work incorrectly and prevent proper compensation of the
installation's current harmonics.
Connect a reactor of at least 3% of the impedance on the input of
each of the loads.
3.2.- INSTALLATION LOCATION
The unit must be installed in an environment where the temperature outside the
cabinet is between 0ºC and 40ºC, with a maximum humidity of 90% without
condensation.
Do not install the unit close to a hot spot and keep it out of direct sunlight.
Ventilation spaces must be left on the side and rear to allow for the use of fans.
There must also be sufficient space at the front of the cabinet to be able to open
the door if necessary ( Figure 12 ):
200 mm on the sides of the cabinet.
200 mm between the top of the cabinet and the ceiling.
800 mm at the front of the cabinet.
