The iSolar Smart Display SD3 is designed for simple con-
nection to iSolar controllers via the iSolar VBus®. The bus
cable can be extended with a two-wire cable (bell wire).
The cable carries low voltage and must not run together in
a cable conduit with cables carrying a higher voltage than
24 V (please pay attention to the valid local regulations
such as VDE regulations for Germany). The cross section
must be at least 0.5 mm2and the cable can be extended up
to 165 ft. in the case of a single connection.
Note:
Protect susceptible furniture surfaces against scratches.
