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

backplane from the chassis power supply. The maximum current

drawn by the CFM module is 0.8A. Add this value to the

requirements of all other modules in the I/O chassis to prevent

overloading the chassis backplane and/or backplane power supply.

ATTENTION

When using a 1771-P7 or 1771-PS7 power supply

to power an I/O chassis, you cannot place more

than four CFM modules in this chassis. The

interaction between the four CFM modules and

the 1771-P7 or 1771-PS7 power supply (not 16A

limit) prevents the power supply from powering

up.
