• Secure any external connections that mate to this equipment by using screws, sliding latches, threaded connectors, or other means provided with this

product.

• Do not disconnect equipment unless power has been removed or the area is known to be nonhazardous.

• Provision shall be made to prevent the rated voltage from being exceeded by transient disturbances of more than 140% of the rated voltage when applied in

Zone 2 environments.

• This equipment must be used only with ATEX/IECEx certified Rockwell Automation backplanes.

• The instructions in the user manual shall be observed.

Prevent 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 wrist strap.

• Do not touch connectors or pins on component boards.

• Do not touch circuit components inside the equipment.

• Use a static-safe workstation, if available.

• Store the equipment in appropriate static-safe packaging when not in use.
