Preventing Electrostatic Discharge

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.

Remove field-side power before removing or

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.
