The AAN(s) shall be mounted directly on the ground plane.
The case of the AAN(s) shall be bonded to the ground plane (ALSE) or connected to the protective earth (OTS, e.g. an earth rod).
The measuring port of each AAN shall be terminated with a 50 Ω load.
If a charging station is used, AAN(s) are not required for the signal/control ports and/or for the wired network ports.
The local/private communication lines between the vehicle and the charging station shall be connected to the associated equipment on the charging station side to work as designed.
If communication is emulated and if the presence of the AAN prevents proper communication then no AAN should be used
2.4.4.
Power charging / local/private communication harness The power charging local/private communication harness shall be laid out in a straight line between the AMN(s) / DC-charging-AN(s) / AAN(s) and the vehicle charging socket and shall be routed perpendicularly to the vehicle’s longitudinal axis (see Figure 3f and Figure 3g).
The projected harness length from the side of the AMN(s) to the side of the vehicle shall be 0,8 (+0,2 / - 0) m.
For a longer harness the extraneous length shall be ‘Z-folded’ in less than 0,5 m width.
If it is impractical to do so because of harness bulk or stiffness, or because the testing is being done at a user installation, the disposition of the excess harness shall be precisely noted in the test report.
The power charging local/private communication harness at vehicle side shall hang vertically at a distance of 100 (+200 / -0) mm from the vehicle body.
The whole harness shall be placed on a non-conductive, low relative permittivity (dielectric-constant) material (εr ≤ 1,4), at (100 ± 25) mm above the ground plane (ALSE) or floor (OTS).

Reference point
3.1.
For the purposes of this annex, the reference point is the point at which the field strength shall be established and shall be defined as follows:
3.2.
For categories M, N, O, T, R and S vehicles according to ISO 11451-2.
3.3.
For category L vehicles:
3.3.1.
At least 2 m horizontally from the antenna phase centre or at least 1 m vertically from the radiating elements of a transmission-line-system (TLS);
3.3.2.
On the vehicle's centre line (plane of longitudinal symmetry).
3.3.3.
At a height of 1.0 ± 0.05 m above the plane on which the vehicle rests or 2.0 ± 0.05 m if the minimum height of the roof of any vehicle in the model range exceeds 3.0 m.
3.3.4.
Either at 1.0 ± 0.2 m behind the vertical centreline of the vehicle's front wheel (point C in Figure 1 of Appendix 1 to this annex) in the case of three-wheeled vehicles.
Or at 0.2 ± 0.2 m behind the vertical centreline of the vehicle's front wheel (point D in Figure 2 of Appendix 1 to this annex) in the case of two-wheeled vehicles.
