INTRODUCTION
This section explains how to configure and install the NTTA01
Translator Termination Unit. Read, understand and complete
the steps in the order they appear before using the TTA termi-
nation unit.
SPECIAL HANDLING
Observe these steps when handling electronic circuitry:
NOTE: Always use Bailey's Field Static Kit (part number 1948385A1
- consisting of two wrist straps, ground cord assembly, alligator clip
and static dissipative work surface) when working with the modules.
The kit grounds a technician and the static dissipative work surface
to the same ground point to prevent damage to the modules by elec-
trostatic discharge.
1.
Use Static Shielding Bag.
Keep the modules in the static
shielding bag until you are ready to install them in the system.
Save the bag for future use.
2.
Ground Bag Before Opening.
Before opening a bag con-
taining an assembly with CMOS devices, touch it to the equip-
ment housing or a 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 Antistatic Field Service Vacuum.
Remove dust from
the module if necessary.
7.
Use 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
earth grounding electrode system through the AC safety
ground.
8.
Do Not Use Lead Pencils to Set Dipswitches.
To avoid
contamination of switch contacts that can result in unneces-
sary circuit board malfunction, do not use a lead pencil to set a
dipswitch.
