SECTION 3 - INSTALLATION
INTRODUCTION
This section explains the procedures required to put the
IMDSI1
digital input module into operation. It includes
instructions on setting the address selection switch, digital
input jumper settings, termination configuration and physical
installation. Information is also provided on wiring connec-
tions and cabling, fusing and preoperating adjustments.
DO
NOT PROCEED
with operation until you read, understand and
complete the steps in the order in which they appear.
SPECIAL HANDLING
NOTE: Always use the Elsag Bailey field static kit (part number
1948385
1, consisting of two wrist straps, ground cord assembly,
alligator clip, and static dissipating work surface when working with
static sensitive devices. The kit is designed to connect the techni-
cian and the static dissipating work surface to the same ground
point to prevent damage to the static sensitive devices by electro-
static discharge.
Use the static grounding wrist strap when installing and
removing modules. Static discharge may damage static sensi-
tive devices on modules in a cabinet. Use grounded equipment
and static safe practices when working with static sensitive
devices.
1.
Use Static Shielding Bag.
Keep the module in its static
shielding bag until you are ready to install it in the system.
Save the bag for future use.
2.
Ground Bags before Opening.
Before opening a bag con-
taining an assembly with static sensitive devices, touch it to
the equipment housing or ground to equalize charges.
3.
Avoid Touching Circuitry.
Handle assemblies by the
edges; avoid touching the circuitry.
4.
Avoid Partial Connection of Static Sensitive Devices.
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 cards if necessary.
7.
Use a Grounded Wrist Strap.
Connect the wrist strap to
the appropriate grounding plug.
