Preventing Electrostatic Discharge
Removing Power
ATTENTION
Electrostatic discharge can damage integrated circuits or semiconductors if you touch
bus connector pins or the terminal block. 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.
