Prevent Electrostatic Discharge
For this reference information
The isolated analog input module is sensitive to electrostatic
discharge. This module is shipped in static-shielded packaging to
guard against electrostatic discharge damage. Observe the following
precautions when handling this module.
ATTENTION: Electrostatic discharge can damage
integrated circuits or semiconductors if you touch
!
backplane 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 backplane connector or
•
connector pins
Do not touch circuit components inside the module
•
If available, use a static-safe work station
•
When not in use, keep the module in its original
