ATTENTION: Risk of equipment damage exists. Remove power before
installing or removing the 1769-SM2 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.
!
ATTENTION: Risk of equipment damage exists. The 1769-SM2
module contains ESD (Electrostatic Discharge) sensitive parts that can be
damaged if you do not follow ESD control procedures. Static control
precautions are required when handling the module. If you are unfamiliar
with static control procedures, refer to Guarding Against Electrostatic
Damage, publication 8000-4.5.2.
