Terminating res-
istors
It may be possible for the system to function without terminating resistors.
However, owing to interference, the use of terminating resistors according to the
following overview is recommended for trouble-free operation.
For permissible cables and max. distances for the data communication area,
refer to the chapter headed Permitted cables for the data communication con-
nection on page 46.
IMPORTANT!Terminating resistors that are not positioned as illustrated can res-
ult in interference in the data communication.
