Recommendations
Standard cable, without any special requirements:
Two-core, flexible, shielded conductor in accordance with VDE 0812, with
colored PVC sheath. PVC insulation resistant to oil, resistant to cold and
petroleum products.
Type: LiYCY 2 x 0,5 mm2
e.g.
Halogen-free cable (no hydrochloric acid is generated when the cable burns):
Halogen-free, highly flexible, resistant to extreme heat and cold. Sheath
manufactured from a special ASS silicon-based composite.
Type: ASS 1 x 2 x 0,5 mm2
e.g.
Recommended if halogen-free and silicon-free cables are required:
Type: BETAflam 145 C-flex. 2x0,5 mm2
e.g.
The total cable length of the USS connection may not exceed 50 m (max. cable
length).
The max. data transfer rate depends on the number of connected nodes (devices)
as well as on the closed-loop control technique / function selection (processor
utilization). Nominal values can be taken from the following table:
