SECTION 3 - INSTALLATION
INTRODUCTION
This section explains how to install and prepare the IIOIS12
(OIS) and IIOIC12 (OIC) for operation. Read and understand
these steps before installing the IIOIS12 or IIOIC12. Call the
local Elsag Bailey sales office if you have any questions about
installing or setting up either the IIOIS12 or IIOIC12.
SPECIAL HANDLING
The IIOIS12/IIOIC12 weighs about 114 kg (250 lbs). Be sure to
move the cabinet with equipment rated for this weight.
HARDWARE SETUP ELECTROSTATIC DISCHARGE (ESD) CONTROL
The OIS contains circuit boards using CMOS components.
Before removing a module from the multibus chassis or the
computer or doing maintenance on equipment having static
sensitive devices read this section.
Static Susceptible Devices (SSD) are likely to be damaged from
contact with potential static charges greater than 6.25 volts.
This potential, when placed across the leads of a SSD can
damage the oxide layers within the package. Latent or immedi-
ate damage may result. Latent damage may not be detectable
under normal circuit check-out, but may result in a reduced
life of equipment or reduced system functions.
Methods for preventing damage involve equalizing the poten-
tials across all SSD terminals and across the SSD working
area, tooling and operator. The most common method is to
connect tools, assembly equipment and the operator electri-
cally to earth ground. This procedure should be followed at all
stages of handling.
Special handling procedures help avoid damage to the printed
circuit boards.
1. Personnel working with or handling printed circuit boards
need to be grounded by wearing conductive wrist ground
straps.
NOTE: Always use the Elsag Bailey Field Static Kit (P/N 1948385A2
- consisting of a wrist strap, ground cord assembly and alligator clip)
when working with the OIS/OIC. 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 dis-
charge.
