• Avoid any pressure data cables! Crushing that effects the wires can have negative effect the transmission characteristics the cable. two different bending radii are listed, i.
Cable laying
Systems
• Lay data cables separate channels from power cable and always cross 90° using bridge. Always check the data sheets for exact specifications.

Technical changes reserved. Never pull the cables over the flange the reel (risk twisting). Bending radius during installation should always bigger than the overall diameter the cable (unless otherwise specified the cable manufacturer).g.Guidelines for the installation unilan® products
Communication technology
Cable pulling
• Always pull cables directly from the drum box. Avoid storing ‘reserve loops’ the patch panel. For cables with intermediate sheath the intermediate sheath and associated foil screen should maintained close possible the point termination. That avoids possible EMC influence. Never expose Uninet data cables direct heat sources. The most frequent reasons crushing are improperly fixed cables, crossing cables and mechanical stress cables.
Heat influence
Fibre optic
• Foamed wires are sensitive direct heat influence.
Terminating the patch panel
• Always follow the connecting hardware manuals. when using heat shrinking tubing. When using reels always use suitable equipment that will ensure free rotation the reel. For cables with pairs metal foil (S/FTP, PiMF) the foil screen should maintained close possible the point termination. Never use hot air gun gas burner, e. Therefore please look «regulations, standards and guidelines». Rewind unused cable and fix the end firmly. Open wires tied with insulating tape between moving equipment and cable sheath (Doesn’t apply cables)
Bending radius
• According EN50173. Use all wires for retracting.
