Installation Guide for Flat Plates

Step 1: corner installation.

Note: to install all elements of the shielding system, suitable fastening devices must be selected according to the type of existing structure. There are dowels available for different construction types on the market (solid or perforated brick, solid or perforated cement, drywall etc.)

The profiles and plates must be perforated prior to fixing with a Ø 7 mm iron carbon bit, or suitable for the dowel you will be using. If envisaged, the upper corner profiles must be installed in the first phase (wall/ceiling), followed by the vertical ones on the walls. The corner profiles placed horizontally must be cut by approximately 45° in the corner joints (see figure to the side), adapting the length of the central profile. It is recommended to use four dowels per side for a corner profile length of 1000mm.

Note: before installing the shielded plates, it is recommended to measure the actual dimensions of the wall/soffi t from various points. If corners are present, measurements must be taken after installing them. The measurements obtained must be compared with those shown in the attached layout. This enables you to highlight any construction differences and enable you to change and adapt the dimensions of the plates (see STEP 3) according to the actual measurements of the structure.

Step 2: installation the first plate.

Note: to start installation, refer to the attached layout. All adjoining plates to the walls or corner profiles, if applicable, must have wings on three sides (except in exceptional cases specified in the layout).

The attached installation layout shows the shielded plate that must be initially installed on the wall, with spatial indication of the direction.

The shielded plates must be positioned in such a way that the high electrical conductivity part (the thickest part with the protruding embossment, see photo) is facing the magnetic fi eld sources.

The first perforated shielding plate that must be installed must have wings on three sides, must overlap the corner profile, if applicable, by approximately 50mm, until reaching the end or aligned with the wall.

Horizontal and vertical alignment must be checked before final securing with dowels, without tightening them too much in order to enable installation of the subsequent side and upper plates.

Step 3: plate installation.

In installation sequence, the second plate that must be used has only one wing on the upper side, and before being secured to the wall must slide, by a depth of approximately 50mm until the end, under the wing of the previously secured plate.

Install the plates one after the other, being careful to alternate the version with one wing with those having three wings.

Note: flat plates that only have one upper wing enable you to recover any construction irregularities of the structure and can be cut on three sides according to requirements. If the sides are cut, you must make up for the difference on the upper wing, bringing it back to its original dimensions (50x55mm, see photo). This must be carried out before securing the last plate having three wings, which, by overlapping, will cover any cutting imperfections.

Step 4: plate installation.

Completion of the first row of plates is completed by using a plate having three wings, which will overlap the previous plate and corner profile, if applicable, or reach the end of the opposite wall.

Step 5: plate installation.

Proceed with installing the plates in the same way described above. If there are any side appendixes, use the same operating procedure (STEP 2).

Step 6: Ceiling plate installation.

After installing the shielding system on the wall, if provided in the layout, start securing the first plate on the ceiling, which must have wings on three sides.

Also in this case, the plate must overlap the corner profile of the one previously installed.

Step 7: Ceiling plate installation.

The second plate that must be used has only one wing on the upper side, and before being secured to the ceiling must slide under the wing of the previously secured plate, by a depth of approximately 50mm and overlapping the wing on the corner profile.

Step 8: ceiling plate installation.

Install the plates one after the other, being careful to alternate the version with one wing with those having three wings.

Step 9: ceiling plate installation.

Proceed with installing the plates, being careful to recover any construction differences of the ceiling, if necessary changing the plate with one wing ( see Note STEP 3).

Step 10: ceiling plate installation.

Completion of the first row of plates is completed by using a plate having three wings, which will overlap the previous plate and corner profile, if applicable, or reach the end of the corresponding slab of the opposite wall.

Step 11: Ceiling plate installation.

After installing all shielding system plates, proceed with tightening the fastening system and, if requested, weld the conductive part, at section intervals of 100mm starting from the intersection of the plates and proceeding throughout the entire perimeter (see drawing). The same method must also be used on the corner profiles and fl at profiles, if applicable

Step 12: final securing of plates.

Earthing the system completes the installation operation of the shielding system.

As there is electrical continuity between the plates, it will suffice to connect the shielding system to an equipotential node of the electrical system, in a point, using a 25 mm² copper wire with relative terminal.

Structural Design of Shielding Plates

It is not always possible to position the shielding plates directly on the wall or ceiling. For this reason Sati Shielding works with specialised companies which are able to provide and assemble metal structures on which to mount the plates.

This solution has made it possible, for example, to screen a distribution transformer located in a museum where the positioning of the shields directly on the wall or ceiling was not an option given the architectural value and the type of wall construction.
