Section 2.2.6 Cable Routing in Cabinets
3BSE 002 415R701 Rev A 2-27
There are some restrictions in mixing cables within a cabinet due to the risk of interference.
To describe the simple rules applicable at site installation, cables are divided in categories.
See Table 2-2 and the following rules:
• Within a category, you can mix cables arbitrarily.
• Keep the distance between cables belonging to different categories
≥
50 mm.
• “Cabinet internal” couplings have their own defined spaces for routing.
Always keep the distance to other cables
≥
50 mm.
Route cables in horizontal cable ducts when applicable.
Fix cables with cable straps.
