Removing Power

ATTENTION: Risk of equipment damage exists. Remove power
before installing or removing the 1769-SM1 module. When you install
!
or remove the module with power applied, an electrical arc may occur.
An electrical arc can cause personal injury or equipment damage by:
• Sending an erroneous signal to your system's field devices, causing
unintended machine motion.
• Causing an explosion in a hazardous environment.
Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical
resistance.
