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.
