Prevent Electrostatic Discharge
WARNING
Electrostatic discharge can damage integrated circuits or semiconductors if
you touch I/O expansion port 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 port connector or connector pins.
•
Do not touch circuit components inside the module.
