About the Modules
This chapter includes important overview information and precautions for use of
the Guard I/O modules that implement the EtherNet/IP safety protocol. Also
included is an overview on how these I/O modules are used within a safety
system.
Before You Begin
Always observe the following when using a module, noting that in this manual we
use safety administrator to mean a person qualified, authorized, and responsible
to secure safety in the design, installation, operation, maintenance, and disposal
of the machine.
• Thoroughly read and understand this manual before installing and
operating the module.
• Keep this manual in a safe place where personnel can refer to it when
necessary.
• Use the module properly according to the installation environment,
performance, and functions of the machine.
• Verify that a safety administrator conducts a risk assessment on the
machine and determines module suitability before installation.
Verify for CE LVD compliance, the external power supply that provides power to
the modules is safety extra-low voltage (SELV) rated. Some Rockwell
Automation Bulletin 1606 power supplies are SELV-compliant. Verify Bulletin
1606 Installation Instructions.
