Electrostatic Discharge
Remove Power
ATTENTION
Electrostatic discharge can damage integrated circuits or semiconductors if you
touch bus connector pins. Follow these guidelines when you handle the
module:
• Touch a grounded object to discharge static potential.
• Wear an approved wrist-strap grounding device.
• Do not touch the bus connector or connector pins.
• Do not touch circuit components inside the module.
• Use a static-safe work station, if available.
• Keep the module in its static-shield box when not in use.
ATTENTION
Remove power before removing or inserting this module. When you remove or
insert a module with power applied, 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 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.
