Section 3
Installation
Introduction
This section contains information needed when installing the
Conductor VMS Series 43 Auxiliary Terminal. It includes infor-
mation on special handling, unpacking and inspection, safety
considerations and wiring considerations.
Following these topics is an installation sequence flowchart
that guides personnel, seeking to perform a specific installa-
tion task, to the proper procedure needed to perform that task.
Special Handling
The auxiliary terminal contains sensitive electronic circuitry.
This circuitry contains semiconductor devices that are subject
to damage by static electricity.
A static field kit (refer to Table 1-4 ) is available for personnel
working on components containing semiconductor devices. It
contains two wrist straps, a ground cord assembly, an alligator
clip and a static dissipating work surface. The intention is to
connect the technician and the static dissipating work surface
to the same ground point to prevent electrostatic discharge
damage to the static sensitive devices.
When handling static sensitive devices:
1. Most assemblies with semiconductor devices come in a
special antistatic bag. Keep the assembly in the bag as much
as possible whenever the assembly is not installed.
2. Remove assemblies containing semiconductor devices from
their antistatic container only under certain conditions:
a. When at a static-free workstation or when the bag is
grounded at a field test sight.
b. Only after neutralizing the conductive area of the
container.
