Safety Precautions
The following safety precautions should be observed before using
this product and any associated instrumentation. Although some in-
struments and accessories would normally be used with non-haz-
ardous voltages, there are situations where hazardous conditions
may be present.
This product is intended for use by qualified personnel who recog-
nize shock hazards and are familiar with the safety precautions re-
quired to avoid possible injury. Read the operating information
carefully before using the product.
The types of product users are:
Responsible body is the individual or group responsible for the use
and maintenance of equipment, and for ensuring that operators are
adequately trained.
Operators use the product for its intended function. They must be
trained in electrical safety procedures and proper use of the instru-
ment. They must be protected from electric shock and contact with
hazardous live circuits.
Maintenance personnel perform routine procedures on the product
to keep it operating, for example, setting the line voltage or replac-
ing consumable materials. Maintenance procedures are described in
the manual. The procedures explicitly state if the operator may per-
form them. Otherwise, they should be performed only by service
personnel.
Service personnel are trained to work on live circuits, and perform
safe installations and repairs of products. Only properly trained ser-
vice personnel may perform installation and service procedures.
Exercise extreme caution when a shock hazard is present. Lethal
voltage may be present on cable connector jacks or test fixtures.The
American National Standards Institute (ANSI) states that a shock
hazard exists when voltage levels greater than 30V RMS, 42.4V
peak, or 60VDC are present.
A good safety practice is to ex-
pect that hazardous voltage is present in any un-
known circuit before measuring.
Users of this product must be protected from electric shock at all
times. The responsible body must ensure that users are prevented
access and/or insulated from every connection point. In some cases,
connections must be exposed to potential human contact. Product
users in these circumstances must be trained to protect themselves
from the risk of electric shock. If the circuit is capable of operating
at or above 1000 volts,
no conductive part of the circuit may be
exposed.
As described in the International Electrotechnical Commission
(IEC) Standard IEC 664, digital multimeter measuring circuits
(e.g., Keithley Models 175A, 199, 2000, 2001, 2002, and 2010)
measuring circuits are Installation Category II. All other instru-
ments’ signal terminals are Installation Category I and must not be
connected to mains.
Do not connect switching cards directly to unlimited power circuits.
They are intended to be used with impedance limited sources.
NEVER connect switching cards directly to AC mains. When con-
necting sources to switching cards, install protective devices to lim-
it fault current and voltage to the card.
Before operating an instrument, make sure the line cord is connect-
ed to a properly grounded power receptacle. Inspect the connecting
cables, test leads, and jumpers for possible wear, cracks, or breaks
before each use.
For maximum safety, do not touch the product, test cables, or any
other instruments while power is applied to the circuit under test.
ALWAYS remove power from the entire test system and discharge
any capacitors before: connecting or disconnecting cables or jump-
ers, installing or removing switching cards, or making internal
changes, such as installing or removing jumpers.
Do not touch any object that could provide a current path to the
common side of the circuit under test or power line (earth) ground.
Always make measurements with dry hands while standing on a
dry, insulated surface capable of withstanding the voltage being
measured.

Do not exceed the maximum signal levels of the instruments and ac-
cessories, as defined in the specifications and operating informa-
tion, and as shown on the instrument or test fixture panels, or
switching card.
When fuses are used in a product, replace with same type and rating
for continued protection against fire hazard
Chassis connections must only be used as shield connections for
measuring circuits, NOT as safety earth ground connections.
If you are using a test fixture, keep the lid closed while power is ap-
plied to the device under test. Safe operation requires the use of a
lid interlock.
If a screw is present, connect it to safety earth ground using the
wire recommended in the user documentation.
The symbol on an instrument indicates that the user should re-
fer to the operating instructions located in the manual.
The symbol on an instrument shows that it can source or mea-
sure 1000 volts or more, including the combined effect of normal
and common mode voltages. Use standard safety precautions to
avoid personal contact with these voltages.
The
WARNING heading in a manual explains dangers that might
result in personal injury or death. Always read the associated infor-
mation very carefully before performing the indicated procedure.
The
CAUTION heading in a manual explains hazards that could
damage the instrument. Such damage may invalidate the warranty.
Instrumentation and accessories shall not be connected to humans.
Before performing any maintenance, disconnect the line cord and
all test cables.
To maintain protection from electric shock and fire, replacement
components in mains circuits, including the power transformer, test
leads, and input jacks, must be purchased from Keithley Instru-
ments. Standard fuses, with applicable national safety approvals,
may be used if the rating and type are the same. Other components
that are not safety related may be purchased from other suppliers as
long as they are equivalent to the original component. (Note that se-
lected parts should be purchased only through Keithley Instruments
to maintain accuracy and functionality of the product.) If you are
unsure about the applicability of a replacement component, call a
Keithley Instruments office for information
To clean the instrument, use a damp cloth or mild, water based
cleaner. Clean the exterior of the instrument only. Do not apply
cleaner directly to the instrument or allow liquids to enter or spill
on the instrument.

Introduction
WARNING
The procedures in this section are
intended only for qualified ser-
vice personnel. Do not perform
these procedures unless qualifie
to do so. Failure to recognize and
observe normal safety precau-
tions could result in personal
injury or death.
The information in this section is arranged as follows:
• Handling precautions  Explains precautions
that must be followed to prevent contamination to the
switch card. Contamination could degrade the perfor-
mance of the card.
•
Multi-pin (mass termination) connections
 Covers the basics for connecting external circuitry to
the connector card.
• Model 7036 installation and removal  Pro-
vides the procedures to install and remove the Model
7036 switch card from the Model 7001/7002 main-
frame.
Handling precautions
To maintain high impedance isolation, care should be taken
when handling the card to avoid contamination from such for-
eign materials as body oils. Such contamination can substan-
tially lower leakage resistances and degrade 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 components. On connectors, do
not touch areas adjacent to the electrical contacts. Dirt
buildup over a period of time is another possible source of
contamination. To avoid this problem, operate the mainframe
and switch card in a clean environment.

Card Connections and Installation

If a card becomes contaminated, it should be thoroughly
cleaned as explained in Section 5.
WARNING
The following connection infor-
mation is intended to be used by
qualified service personnel. Fail-
ure to recognize and observe
standard safety precautions
could result in personal injury or
death.
Multi-pin (mass termination)
connections
Since connections to external circuitry are made at the 96-pin
male DIN bulkhead connector, there is no need to separate
the connector card from the relay card. If the connector card
is separated from the relay card, carefully mate them
together and install the supplied 4-40 screw to secure the
cards. Make sure to handle the cards by the edges and shields
to avoid contamination.
Terminal identification for the DIN connector of the multi-
pin connector card is provided by Figure 3-1 and Table 3-1.
This connector will mate to a 96-pin female DIN connector.

Card Connections and Installation
3-4
Keithley has a variety of cable and connector accessories
available to accommodate connections from the connector
card to test instrumentation and DUTs (devices under test).
In general, these accessories, which are summarized in
Table 3-2, utilize a custom-built cable assembly for
connections.
Typical connection technique
All external circuitry, such as instrumentation and DUTs,
that you want to connect to the switch card must be termi-
nated with a single 96-pin female DIN connector. The fol-
lowing connection techniques provide some guidelines and
suggestions for wiring your circuitry.
WARNING
Before beginning any wiring pro-
cedures, make sure all power is
off and stored energy in external
circuitry is discharged.
WARNING
When wiring a connector, do not
leave any exposed wires. No con-
ductive part of the circuit may be
exposed. Properly cover the con-
ductive parts, or death by elec-
tric shock may occur.
CAUTION
The 7011-MTC-2 cable is not
intended to be used with the
Model 7036. Pins 1 and 33 in the
cable are internally shorted, but
the Model 7036 uses these pins
for signaling. Using the 7011-
MTC-2 cable with the Model 7036
will short out the system and
cause equipment damage.
NOTE
It is recommended that external cir-
cuitry be connected (plugged in) after
the Model 7036 is installed in the Model
7001/7002 mainframe. Installation is
covered at the end of this section.
In Figure 3-2, connections are accomplished using a custom-
built cable assembly that consists of a Model 7011-KIT-R
connector and a suitable round cable. Hitachi part number
N2807-P/D-50TAB is a round, 50-conductor cable. Two
cables can be used to provide 100 conductors. The connector
has solder cups to accommodate the individual wires of the
unterminated cable. Figure 3-3 provides an exploded view of
the connector assembly and shows how the cable is con-
nected. For further Model 7011-KIT-R assembly informa-
tion, refer to the packing list provided with the kit. The
connector end of the resultant cable assembly mates directly
to the multi-pin connector card. The unterminated end of the
cable assembly is wired directly to instrumentation and
DUT.
