Installation Guide | Advanced Active Filter AAF 007
This equipment is not intended for use in residential locations and will not guarantee to provide adequate protection to radio
reception in such locations.
The IP20/open type filter shall be installed in electrical cabinets or facilities with restricted access only for skilled personnel.
Full output current is available when the following installation conditions are met:
Maximum ambient air temperature: 40 ºC (104 ºF), derating 3%/K, maximum 50 °C (122 °F)
l
Minimum ambient air temperature: -10 ºC (14 ºF).
l
Thermal conditions: Altitude < 1000 m (3280 ft) above sea level, current derating 5%/1000 m (3280 ft), maximum 4000 m (13123 ft).
l
Relative humidity: 5–95% (non-condensing).

2.1 1section shows examples of the entire installation.
1.
Ensure that the operating environment and electrical installation meet the following conditions:
a. Indoor unconditioned/pollution degree 2.
b. Overvoltage category 3.
2.
For correct thermal protection, provide the required clearance above and below the filter.
3.
Ensure that the current Transformer (CT) meets the requirements described in
CT and the according cables, refer to
4.
Install the filter following the numbered steps in the Illustrations section.
a.
Mount the filter using the intended fixtures on or against a solid and plain metal surface. Ensure required airflow of 160 m
h per module of 35 A or 55 A and 350 m
b.
Install the control wiring.
c.
Install the current sensor wiring (refer to step 3 in the Illustrations section).
d. Install the mains wiring (refer to step 4 in the Illustrations section).
Connect 2 of the PE terminals to the local PE connections in the installation to ensure redundancy and sufficient
grounding surface on the filter (For 55 A and 35 A only)
5.
Securely fasten the mains cover to the filter.
6. Ensure correct wiring of the current Transformers:
a. Check the correct direction/polarity of the CT: P1 towards the point of common coupling.
b.
Check the correct polarity of CT cables: S1 to CTX and S2 to ground (refer to step 7 in the Illustrations section).
c.
Check the correct order of CT to filter terminals: L1:CTA, L2:CTB, L3:CTC. L2:CTB is only required for 4-wire systems with
neutral.
d. Check the correct sequence of grid phases installation.
e.
Ensure the right position of the CT according to the setting in the filter. Load side or grid side.
Routing of wires: The wires between AAF 007 and the current transformers must be twisted pair cables. A correct
function is only possible if the wiring exactly matches the upper diagram in step 7 in the Illustrations section. If wires are
interchanged, the harmonics are not to be reduced, but amplified. To avoid interchanging of wires, do not use any wire
color twice.
