Figure 12: Active filter spaces for ventilation.
Install the AFQ-4W in a place protected from water, flammable
liquids, gases and corrosive substances.
Make sure there are no reactive compensation units installed in the
same mains as the AFQ-4W. If there are any compensation units,
these must be untuned in order to avoid interference between them
and the AFQ-4W.
3.3.- STORAGE FOR LONG PERIODS
If the unit is not installed after receipt, the following recommendations must be
observed to keep the unit in a good state:
Keep the unit in a dry atmosphere and at a temperature of between 0ºC
and 50ºC.
Avoid exposure to direct sunlight.
Keep the unit in its original packaging.
If the active filter is stored for a long time disconnected from the mains, a
process must be applied to restore the internal dielectric layers of the DC bus
capacitors. Table 2 shows the recommendations for starting the unit depending
on the length of its storage period.
