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.

Your module receives its power through the 1771 I/O chassis

backplane from the chassis power supply. The maximum current

drawn by the module from this supply ranges from 1.5 to 3.3A,

dependent upon the particular type of module. Refer to the

specifications in appendix A for standard modules.
