Instruction Manual
3�5�- CONNECTION
Wall and Rack type AFQm
models
:
Use cables of a cross-section suitable for the rated current of the filter and that comply
with the standards of the country in which they are being installed.
The earth conductor must have at least the same cross-section as the phase conduc-
tors. If the phase conductors exceed 16 mm
2
, the earth conductor will be at least 16
mm
2
. If the phase conductors exceed 32 mm
2
, the earth conductor can be the half of the
cross-section of the phase conductors
For
100A models
(
AFQm-xxx-100M
and
AFQm-xxx-100R
), under certain circumstanc-
es, the contact current may exceed 3.5 mA ~.
The recommended minimum cross-sections are
(1)
:
AFQm-xxx-030M :
16 mm
2
AFQm-xxx-060M : 25 mm
2
AFQm-xxx-100R
and
AFQm-xxx-100M :
50 mm

Neutral conductor cross-section must suit the expected neutral current and must be
selected according to the external protection devices.
Cabinet
type AFQm
models
:
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 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 recommended
minimum cross-sections are
(1)
:
AFQm-xxx-070C: 35 mm
2
AFQm-xxx-100C:
50 mm
2
AFQm-xxx-140C: 70 mm
2
AFQm-xxx-200C:
95 mm
2
AFQm-xxx-210C:
120 mm
2
AFQm-xxx-300C: 150 mm
2
AFQm-xxx-280C:
150 mm
2
AFQm-xxx-400C: 240 mm

Neutral conductor cross-section must suit the expected neutral current and must be
selected according to the external protection devices.

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
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.
