Installing the Filter

WARNING: SHOCK HAZARD
Touching hazardous live parts can result in death or serious injury. This IP20/open type filter does not provide protection against direct contact to hazardous live parts. It is intended to be installed inside a supplementary enclosure or in a restricted-access area which provides appropriate protection against electric shock.

NOTICE

  • For compliance with EN/IEC 61000-6-8:2020, it is important that the filter is professionally installed and maintained. The professional installer shall evaluate the EMC situation before installation, if the equipment is installed closer than 30 m (98.4 ft) to a residential location.
  • This equipment is not intended for use in residential locations and will not guarantee to provide adequate protection to radio reception in such location.
  • The IP20/open type filter shall be installed in electrical cabinets or facilities with restricted access only for skilled personnel.

The installation location is important.

  • Full output current is available when the following installation conditions are met.
  • Maximum surrounding air temperature: 40 ºC (104 ºF), derating 3%/K, maximum 50 °C (122 °F)
  • Minimum surrounding air temperature: -10 ºC (14 ºF).
  • Thermal conditions: Altitude < 1000 m (3280 ft) above sea level, current derating 5%/1000 m (3280 ft), maximum 4000 m (13123 ft).
  • Relative humidity is 5–95% (non-condensing).
  • Step 1 in the Illustrations section shows examples of the entire installation. The lower drawing is an example of a parallel installation of filter modules.

Procedure

  1. Ensure that the operating environment and electrical installation meet the following conditions.
    1. Indoor unconditioned/pollution degree 2.
    2. Overvoltage category 3.
    3. Not for use in wet locations.
  2. For correct thermal protection, provide the required clearance above and below the filter.
  3. Ensure that the current transducer (CT) meets the following requirements described in 1.8 Current Transducers, especially when it has not been ordered with the filter. For correct selection of CT and the according cables, refer to 1.11 Cable and
    1. Fuse Specifications.
    2. Install the filter following the numbered steps in the Illustrations section.
    3. Mount the filter on or against a solid and plain metal surface. Ensure required airflow of 160 m3/h per module for proper cooling. Refer to step 2 in the Illustrations section.
    4. Install the control wiring.
    5. Install the current sensor wiring (refer to step 3 in the Illustrations section).
    6. Install the mains wiring (refer to step 4 in the Illustrations section).
  4. Securely fasten the mains cover to the filter.
  5. Ensure correct wiring of the current transducers by:
    1. Checking correct direction/polarity of the CT: P1 towards the point of common coupling.
    2. Checking correct polarity of CT cables: S1 to CTX and S2 to groundX (refer to step 7 in the Illustrations section).
    3. Checking correct order of CT to filter terminals: L1:CTA, L2:CTB, L3:CTC. L2:CTB is only required for 4-wire systems with neutral.
    4. Checking correct sequence of grid phases installation.
    5. Ensuring the right position of the CT according to the setting in the filter. Load side or grid side.
    6. 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.
  6. When the filter is connected to mains, it will start operation. Check that the wiring is correct by assessment of the improvement of the power quality either with the PC tool for filter or with a power quality meter. Consult the operating guide for further information.

Parallel Installation

  • It is possible to install the filter modules in parallel to increase the filters’ output current. If filter modules are installed in parallel, 1 CT set could be used for all parallel filter modules. Wire the CT’s secondary wires in series from the CT to filter module 1, to module 2, to module X, and back to the CT terminals S2 or I, see step 1 in the Illustrations section.
  • For correct wiring of the current transducer when having 2 filters, refer to step 5 in the Illustrations section.
  • For correct wiring of the current transducer when having more than 2 filters, refer to step 6 in the Illustrations section. Ensure that the CT configuration is configured to “series” (default) when applying series connection of CTs as described in steps 5 and 6 in the Illustrations section.
  • Refer to step 2 in the Illustrations section for correct clearance distances what ensures correct operation in respect to thermal and electro-magnetic considerations.

Current Transducers

  • The Advanced Active Filter AAF 007 needs extra current transducers (CTs). The possible installations of the CTs are on the mains side/closed loop, which measures the mains current, including the filter output current, and on the load side/open loop, which measures just the load current without the filter current.
  • On both settings, a CT is required. A CT set consists of 2 CTs. A 3-phase 3-wire system has 3 conductors but just 2 phase currents/
    conductors are measured with CTs on phase L1 and phase L3. Phase 2 is calculated internally. If 3 CTs are already existing, only phases L1 and L3 has to be connected to the filter.
  • If the current transducers are already in the installation or are ordered separately to the filter, ensure that they meet the following specifications to guarantee the expected performance of the filter:
    • Minimum burden 2.5 VA
    • Minimum accuracy class 0.5
    • 5 A secondary current
  • The cross-section of the wires has a significant influence on the quality of the control. If the cross-section is too small in relation to the wire length, the resulting measurement will be too small to achieve a good control quality and good reduction of harmonics. A = 2 × d × v × I2 × ρ/ S
  • The following values need to be known:
    • S = Power of the current transformer (typically 2.5 VA)
    • d = Distance (length of cableway) between filter and current transformer
    • v = Twisting factor (typically 1.5)
    • I = Secondary current of the current transformer (typically 5 A)
    • ρ = Rho = Specific resistance of copper (0.01786 Ω×mm2/m )

Example:  = 2 × 2m× 1 . 5 × 52 × 0 . 01786 Ω×m/2 . 5 VA ×mm2 = 1 . 07 mm2

Four-wire System

  • All descriptions in the previous sections and following illustrations are targeting 3-wire systems. The filter can also operate in 4-wire systems. Additional to the steps already described and illustrated, the following must be done:
  • A 3rd CT must be installed on phase 2/phase B. The Neutral wire must be connected to the mains terminal. In the PC tool for the filter, adjust the grid topology to 3P4W.

NOTICE
FILTER MALFUNCTION

  • Connecting the neutral wire in 3-wire applications will cause the filter to work improperly.
  • Do not connect the neutral wire in 3-wire applications.
