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.

ATTENTION
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.
