INTRODUCTION
This section explains how to install the Thermocouple Analog
Input Termination Unit (NTAI02). Read, understand, and com-
plete the steps in the order they appear before using the
NTAI02 unit.
SPECIAL HANDLING
Observe these steps when handling electronic circuitry:
NOTE: Always use the Bailey Controls Field Static Kit (part number
1948385A1 - consisting of two wrist straps, ground cord assembly,
alligator clip and a static dissipating work surface) when working
with modules. The kit is designed to connect the technician and the
static dissipating work surface to the same ground point to prevent
damage to the modules by electrostatic discharge.
Use the static grounding wrist strap when installing and removing
modules. Static discharge may damage MOS devices on modules in
the cabinet. Use grounded equipment and static safe practices
when working with modules.
1.
Use Antistatic Bags.
Keep the modules in the antistatic
bag until you are ready to install them in the system. Save the
bag for future use.
2.
Ground Bags Before Opening.
Before opening a bag con-
taining an assembly with CMOS devices, touch it to the equip-
ment housing or ground to equalize charges.
3.
Avoid Touching Circuitry.
Handle assemblies by the
edges; avoid touching the circuitry.
4.
Avoid Partial Connection of CMOS Device.
Verify that all
devices connected to the modules are properly grounded before
using them.
5. Ground Test Equipment.
6.
Use an Antistatic Field Service Vacuum
. Remove dust
from the module if necessary.
7.
Use a Grounded Wrist Strap.
Connect the wrist strap to
the appropriate grounding plug on the power entry panel. The
grounding plug on the power entry panel is connected to the
cabinet chassis ground.
