Install or Remove the Module Under Power

This module is designed to be installed or removed while chassis power is

applied.

WARNING

When you insert or remove a module while

backplane power is on, an electrical arc may

occur. An electrical arc can cause personal injury

or property damage by:

• sending an erroneous signal to your system’s field

device causing unintended machine motion or loss

of process control

• causing an explosion in a hazardous environment

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.
