Open wires tied with insulating tape between moving equipment and cable sheath (Doesn’t apply cables)
Bending radius
• According EN50173.: bend radius with the higher value during installation bend radius with the lower value after installation
Copper screened
Pressure data cables
Copper unscreened
• Avoid any pressure data cables! Crushing that effects the wires can have negative effect the transmission characteristics the cable.
Terminating the patch panel
• Always follow the connecting hardware manuals. Rewind unused cable and fix the end firmly. Never pull the cables over the flange the reel (risk twisting). That avoids possible EMC influence. two different bending radii are listed, i. Always check the data sheets for exact specifications. When using reels always use suitable equipment that will ensure free rotation the reel.

Technical changes reserved. when using heat shrinking tubing. 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.Guidelines for the installation unilan® products

Cable pulling
• Always pull cables directly from the drum box. Bending radius during installation should always bigger than the overall diameter the cable (unless otherwise specified the cable manufacturer).e. Use all wires for retracting.g. For cables with pairs metal foil (S/FTP, PiMF) the foil screen should maintained close possible the point termination. Therefore please look «regulations, standards and guidelines». For cables with intermediate sheath the intermediate sheath and associated foil screen should maintained close possible the point termination.

Cable laying
Systems
• Lay data cables separate channels from power cable and always cross 90° using bridge. Never use hot air gun gas burner, e. Avoid storing ‘reserve loops’ the patch panel. Never expose Uninet data cables direct heat sources
