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.

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 70A or 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 recom-
mended minimum cross-sections are
AFQm-xxx-070C: 35 mm
AFQm-xxx-100C: 50 mm
AFQm-xxx-140C: 70 mm
AFQm-xxx-200C: 95 mm
AFQm-xxx-210C: 120 mm
AFQm-xxx-300C:150 mm
AFQm-xxx-280C: 150 mm
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.
Ensure that the AFQm IP54 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.
The correct connection of the current transformers is vital for the AFQm IP54 filters to
operate properly. If the phases L1, L2 and L3 are switched in the secondary, the filter
will not work properly.
The AFQm IP54 devices have built-in fuse overcurrent protection.
Install external protection according to the type of installation, the facility's maximum
short-circuit current, the maximum fuse current, and the regulations in force at the
place of installation.
If local regulations require the use of earth leakage protection devices, only DC sensitive
RCD (RCD type B) should be used with AFQm IP54. Active filters work internally with
DC currents, and, in case of failure, the DC currents may produce malfunction on type
A RCD devices.
Ensure that the installation of the device in your electric distribution system (TN, VT, IT)
complies with current standards.
