Making the LON connection
The Viessmann LON is designed for
"line" bus topology with a terminator at
both ends (accessories).
The transfer distances for LON are sub-
ject to the electrical properties of the
relevant cable. For this reason, only
use the specified cable types. Use only
one cable type within each LON.
Cable types (on site):
■ 2-core cable, CAT5, screened
■ JY(St)Y 2 x 2 x 0.8 mm (telephone
cable)
10
B LON communication module
Observe the requirements for cabling
and operation of the LON interface FTT
10-A.
All Viessmann appliances are connec-
ted with RJ45 connectors. The
Viessmann LON always requires cores
"1" and "2" plus the screen. The cores
are interchangeable.
Note
When connecting external switching
contacts and on-site components,
observe the insulation requirements of
IEC/EN 60335-1.
