ATTENTION
Electrostatic discharge can damage integrated circuits or
semiconductors if you touch analog I/O module bus-connector pins
or the terminal block on the module. 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 it is not in use.
