3.1
Introduction
WARNING
The procedures in this section are
intended only for qualified service
personnel. Do not perform these pro-
cedures unless qualified to do so.
Failure to recognize and observe nor-
mal safety precautions could result
in personal injury or death.
The information in this section is arranged as follows:
3.2
Handling precautions
Explains precautions
that must be followed to prevent contamination
to the switch card assembly. Contamination
could degrade the performance of the switch
card.
3.3
Connections
Covers the basics for connecting
external circuitry to the two available connector
cards; the screw terminal connector card and the
multi-pin connector card.
3.4
Typical connection schemes
Provides some
typical connection schemes for single card, two-
card, and two-mainframe system configurations.
3.5
Model 7013 installation and removal
Pro-
vides the procedures to install and remove the
switch card assembly in the Model 7001 main-
frame.
3.2
Handling precautions
To maintain high impedance isolation, care should be
taken when handling the relay card to avoid contami-
nation from such foreign materials as body oils. Such
contamination can substantially lower leakage resis-
tances, thus degrading performance.
To avoid possible contamination, always grasp the
relay card and the connector card by the side edges or
shields. Do not touch the board surfaces or compo-
nents. On connectors, do not touch areas adjacent to
the electrical contacts. Dirt build-up over a period of
time is another possible source of contamination. To
avoid this problem, operate the mainframe and switch
card assembly in a clean environment.
If a card becomes contaminated, it should be thor-
oughly cleaned as explained in paragraph 5.2.
3.3
Connections
This paragraph provides the basic information needed
to connect your external test circuitry to the switch
card. It includes detailed information on the two avail-
able connector cards.
