Never pull the cables over the flange the reel (risk twisting). The most frequent reasons crushing are improperly fixed cables, crossing cables and mechanical stress cables. 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. Never expose Uninet data cables direct heat sources. For cables with intermediate sheath the intermediate sheath and associated foil screen should maintained close possible the point termination. When using reels always use suitable equipment that will ensure free rotation the reel. Never use hot air gun gas burner, e.Guidelines for the installation unilan® products
Communication technology
Cable pulling
• Always pull cables directly from the drum box. when using heat shrinking tubing. For cables with pairs metal foil (S/FTP, PiMF) the foil screen should maintained close possible the point termination. Avoid storing ‘reserve loops’ the patch panel. two different bending radii are listed, i.e.
Heat influence
Fibre optic
• Foamed wires are sensitive direct heat influence. That avoids possible EMC influence.: 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.

Technical changes reserved. Therefore please look «regulations, standards and guidelines». Bending radius during installation should always bigger than the overall diameter the cable (unless otherwise specified the cable manufacturer). Rewind unused cable and fix the end firmly.
Cable laying
Systems
• Lay data cables separate channels from power cable and always cross 90° using bridge.g.
Terminating the patch panel
• Always follow the connecting hardware manuals.
. Always check the data sheets for exact specifications
