Installation conditions

Internal application

L2-BUS cables are intended for connecting components (standard 485) and transmission of analogue and digital signals. Paired construction ensures good symmetry with respect to earth, while the double screen protects against interferences from external electromagnetic fields, what guarantees very good transmission quality. Cables may be used in dry and damp rooms, and are suitable for fixed installations. For outdoor installations, we have developed the BiT L2 BUS outdoor 02YS(St)C2Y cable with a polyethylene sheath that is resistant to UV radiation. Cables classified according to EN 50575 (CPR).
