FLEX I/O Electronically Fused 8 Output Module

ATTENTION
!
FLEX I/O is grounded through the DIN rail to
chassis ground. Use zinc plated, yellow chromated
steel DIN rail to assure proper grounding. Using
other DIN rail materials (e.g. aluminum, plastic, etc.)
which can corrode, oxidize or are poor conductors
can result in improper or intermittent platform
grounding.

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.
•
If available, use a static–safe workstation.
•
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.
