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 m5V 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.
