Installing or Removing the Module Under Power
This module is designed to be installed or removed while chassis power is
applied.
WARNING
Wire the EtherNet/IP Connector
Use an RJ45 connector to connect to the EtherNet/IP network. Wire the
connector according to the following illustration:
8 ------ NC
7 ------ NC
6 ------ RD-
5 ------ NC
4 ------ NC
3 ------ RD+
2 ------ TD-

For detailed EtherNet/IP connection information, see the EtherNet/IP Media
Planning and Installation Guide, publication number ENET-IN001.
When you insert or remove the module while backplane
power is on, an electrical arc can occur. This could cause
an explosion in hazardous location installations.
Be sure that power is removed or the area is
nonhazardous before proceeding. Repeated electrical
arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may
create electrical resistance that can affect module
operation.
