Product Dimensions：

This chapter includes important information and precautions for using

Guard I/O modules that implement the DeviceNet safety protocol and how to 

use the modules within a safety system.

Before You Begin Always observe the following guidelines 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 this in the Bulletin 1606 Installation Instructions.
