Electrostatic Damage

Electrostatic discharge can damage semiconductor devices inside this module if you

touch backplane connector pins. Guard against electrostatic damage by observing

the following precautions.

1746-NI8 Power Requirements

The 1746-NI8 module receives its power through the SLC 500™ chassis backplane

from the fixed or modular +5V dc/+24V dc chassis power supply. The +5V dc

backplane supply powers the SLC circuitry and the +24V dc backplane supply

powers the module analog circuitry. The maximum current drawn by the module is

shown in the table below.

When you are using a modular system configuration, add the values shown in the

table above to the requirements of all other modules in the SLC chassis to prevent

overloading the chassis power supply.

ATTENTION

Electrostatic discharge can degrade performance or cause

permanent damage. Handle the module as stated below.

• Wear an approved wrist strap grounding device when

handling the module.

• Touch a grounded object to rid yourself of electrostatic charge

before handling the module.

• Handle the module from the front, away from the backplane

connector. Do not touch backplane connector pins.

• Keep the module in its static-shield bag when not in use, or

during shipment.
