Wire the Module
Ground the Module
You must provide an acceptable grounding path for each device in your 
application. For more information on proper grounding guidelines, refer to the 
Industrial Automation Wiring and Grounding Guidelines, publication number 
1770-4.1.
The I/O module is functionally grounded through its DIN rail connection. A 
protective earth ground connection is required and is provided by a separate 
grounding screw, located on the upper left of the housing and marked with the 
grounding symbol
.
Connections for Safety-Related Communications
Ethernet Switch
The module has two 10/100BaseT, RJ-45 connectors, located on the bottom of the 
unit, that provide communications to the GuardPLC controller via GuardPLC 
Ethernet. Because this is an Ethernet switch, you can daisy-chain connections from 
the GuardPLC to other distributed I/O blocks. The switch is auto-detect. Either 
cross-over or straight-through shielded Ethernet cabling can be used.
Star or line configurations are available. Make sure that a network loop is not 
generated. Data packets must only be able to reach a node via a single path. Ring 
topology is not supported.
MAC Address
The Media Access Control (MAC) Address of the module can be found on the label 
positioned over both lower RJ-45 connections.
ATTENTION
This product is grounded through the DIN rail to chassis ground. 
Use zinc plated yellow-chromate steel DIN rail to assure proper 
grounding. The use of other DIN rail materials (e.g. aluminum, 
plastic, etc.) that can corrode, oxidize, or are poor conductors, 
can result in improper or intermittent grounding.
