SECTION 3 - INSTALLATION
INTRODUCTION
This section covers the proper handling of devices susceptible
to electrostatic discharge, dipswitch and jumper settings, and
termination unit or module installation. Follow the steps in this
section to install and prepare a specific interface for operation.
SPECIAL HANDLING
The INFI-NET to INFI-NET interface modules have components
that are sensitive to electrostatic discharge. Follow these han-
dling procedures:
NOTE: Always use Bailey's field static kit (part number 1948385_1 -
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 semiconductors, touch it to the
equipment 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 Semiconductors.
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 must be effectively
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 dipswitch contacts that can result in unnec-
essary circuit board malfunction, do not use a lead pencil to
set a dipswitch.
