Prevent Electrostatic Discharge
Removal and Insertion Under Power
ATTENTION
This equipment is sensitive to electrostatic discharge, which can cause internal
damage and affect normal operation. Follow these guidelines when you handle
this equipment:
• Touch a grounded object to discharge potential static.
•
Wear an approved grounding wriststrap.
•
Do not touch connectors or pins on component boards.
•
Do not touch circuit components inside the equipment.
•
Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in
use.
•
Post a sign near these modules:
Attention! Avoid electrostatic charging.

WARNING
These modules are designed so you can remove and insert them under
power. However, take special care when removing or inserting modules in an
active process. I/O attached to any module being removed or inserted can
change states due to its input/output signal changing conditions.
If you insert or remove the terminal base while backplane power is on, an
electrical arc can occur. This could cause an explosion in hazardous location
installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
