ATTENTION
Preventing Electrostatic Discharge
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.
•
If available, use a static–safe workstation.
•
When not in use, keep modules in appropriate
static–safe packaging.
!
WARNING Remove field-side power before removing or
inserting this module. This module is designed so
you can remove and insert it under backplane
power. When you remove or insert a module with
field-side power applied, an electrical arc may
occur. An electrical arc can cause personal injury or
property damage by:
•
sending an erroneous signal to your system’s
field devices causing unintended machine motion
•
causing an explosion in a hazardous environment
Repeated electrical arcing causes excessive wear to
contacts on both the module and its mating
connector. Worn contacts may create electrical
resistance.
