<1> Connect the provided ground wire during installation.

Communication Cable Topology
The option modular connector CN1 port 1 and port 2 act as a switch to allow for flexibility in cabling topology. For
example, a traditional star network topology may be employed by using a single port on the option board. Alternatively,
a daisy-chained approach may be employed by using both option modular connector ports. This second approach reduces
the requirements of PROFINET switch ports.
