AFQm IP54
ENGLISH
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 (

)

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,

If dust can enter the device from the bottom, these windows will have to be machined and suitable
cable glands installed for the cables.
