EXCAVATION The excavation must be equivalent to the outer dimensions of the bed enlarged by approx. 40 cm to allow for peripheral compaction. The bottom of the excavation must have a bearing capacity of 2 bars, be protected from frost, at 50 cm minimum, and not be situated at groundwater level. POSITIONING OF THE FOUNDATION Position the foundation using the hoisting means provided for that purpose: Place the foundation on a 10 cm minimum bed of sand respecting the 40 cm from the sides of the excavation taking care, for the AC foundation, to orient the strut according to the final position of the terminal. Guarantee the perfect level with a spirit level. Once the ducts and cables have been passed, fill the foundation with sand up to half-height to prevent rodents from climbing up the inside of the terminal. Seal the unused through-going openings at the foot of the bed with the plugs provided for this purpose. BACKFILLING The backfill must be done with 0/31.5 bank gravel, or any other equivalent material, in successive compacted layers of 30 cm. FASTENING OF THE PLATE Ensure that the upper part of the foundation is clean and clear of any gravel or other matter that could destabilize the device. After filling the attachment points with an appropriate grease, screw the anchoring plate into the intended inserts or openings with a recommended tightening torque of 18 Nm. AC Foundation on the central strut with an approved lifting stud. QC Foundation on hoisting studs with an approved lifting eye 1t3. HPC Foundation on lifting studs with an approved lifting eye 2t5.

MAIN PRINCIPLES FOR THE INSTALLATION OF THE PLATES AND PROTECTIONS

Position and fix the terminal in place. ANTI-COLLISION PROTECTION (OPTION)

Install the protection system directly on the foundation using the apertures intended for this purpose. The poles’ dowels should be positioned above the final ground level in a manner that permits, if necessary, the easy replacement of a damaged pole.
