ATTENTION
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.
•

When not in use, keep modules in appropriate
static–safe packaging.
!
ATTENTION
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.
