2.2.2 Prevent Electrostatic Discharge
Electrostatic discharge can damage integrated circuits or semiconductors if
you touch the module card bus connector pins or the terminal block on the
output 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.
