Electrostatic Discharge
Remove Power
IMPORTANT
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.
•
Do not touch the bus connector or connector pins.
•
Do not touch circuit components inside the module.
IMPORTANT
Remove power before removing or inserting a module in the I/O
line-up. 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 damage to the product
Electrical arcing causes excessive wear on module contacts Worn
contacts may create electrical resistance.
