Mounting and wiring
Note: All the Bus Terminals are electrically isolated from the K-bus. The K-bus is thus electrically isolated
from everything else.

The LC5200 does not provide electrical isolation from the fieldbus and peripheral level. If the peripheral level
nevertheless needs to have an electrically isolated implementation, this can easily be achieved through the
use of isolating terminals (KL9xxx).
