6 Preface

WARNING

When you insert or remove the module while backplane power is on,

an electrical arc can occur. This could cause an explosion in

hazardous location installations. Be sure that power is removed or the

area is nonhazardous before proceeding.

ATTENTION

FLEX I/O is grounded through the DIN rail to chassis ground. Use zinc

plated yellow-chromate steel DIN rail to assure proper grounding. The

use of other DIN rail materials (such as aluminum or plastic) that can

corrode, oxidize, or are poor conductors, can result in improper or

intermittent grounding.

ATTENTION

Prevent 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.

ATTENTION

During mounting of all devices, be sure that all debris (such as metal

chips or wire strands) is kept from falling into the module. Debris that

falls into the module could cause damage on power up.
