The equipment is configured and connected to satisfy its functional requirements. It shall be placed on the GRP with the interposition of a 0,1 m thickness insulating support (e.g. dry wood).
The equipment cabinets shall be connected to the safety earth directly on the GRP via the earth terminal of the EUT.
The power supply, input and output circuits shall be connected to the sources of power supply, control and signal.
The cables supplied or recommended by the equipment manufacturer shall be used. In absence of any recommendation, unshielded cables shall be adopted, of a type appropriate for the signals involved. All cables shall be exposed to the magnetic field for 1 m of their length.
The back filters, if any, shall be inserted in the circuits at 1 m cable lengths from the EUT and connected to the ground plane.
The communication lines (data lines) shall be connected to the EUT by the cables given in the technical specification or standard for this application.
The test generator shall be placed at less than 3 m distance from the induction coil.
One terminal of the generator shall be connected to the ground plane as far as used.
7.4 Induction coil
The induction coil, of the type specified in 6.2.1, shall enclose the EUT placed at its centre.
Different induction coils may be selected for testing in the different orthogonal directions, according to the general criteria specified in 6.2.1 a) and b).
Induction coils used in the vertical position (horizontal polarization of the field) can be bonded (at the foot of one vertical conductor) directly to the ground plane, which represents the low side of the coil, as a part of it. In this case, 0,1 m minimum distance from EUT to the ground plane is sufficient.
The induction coil shall be connected to the test generator in the same way as for the calibration procedure specified in 6.2.2.
The induction coil selected for the tests shall be specified in the test plan.
