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:
Required Tools and Equipment
Have the following tools and equipment ready:
•
2.5 mm (0.1 in.) slot-head screwdriver
•
thermocouple or millivolt sensor
•
appropriate thermocouple extension wire (if needed)
•
thermocouple/mV input module (1746-NT8)
•
programming equipment
Power Requirements
The module receives its power through the SLC 500 chassis backplane from the
fixed or modular +5V dc/+24V dc chassis power supply. The maximum current
drawn by the module is shown in the following table.
ATTENTION
!
ELECTROSTATICALLY SENSITIVE COMPONENTS
•
Before handling the module, touch a grounded object to rid
yourself of electrostatic charge.
•
Handle the module from the front, away from the
backplane connector. Do not touch backplane connector
pins.
•
Keep the module in its static-shield container when not in
use or during shipment.
Failure to observe these precautions can degrade the module’s
performance or cause permanent damage.
