The following safety precautions should be observed before using this product and any
associated instrumentation. Although some instruments and accessories would normally be
used with nonhazardous voltages, there are situations where hazardous conditions may be
present.
This product is intended for use by personnel who recognize shock hazards and are familiar
with the safety precautions required to avoid possible injury. Read and follow all ins
operation, and maintenance information carefully before using the product. Refer to the user
documentation for complete product specifi cations.
If the product is used in a manner not specifi ed, the protection provided by the product

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.

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.
For safety, instruments and accessories must be used in accordance with the operating
instructions. If the instruments or accessories are used in a manner not specifi ed in t
operating instructions, the protection provided by the equipment may be impaired.
Do not exceed the maximum signal levels of the instruments and accessories. Maximum signal

Important test system safety information
This system contains instruments that can produce
hazardous voltages. It is the responsibility of the test system
installer, maintenance personnel, and service personnel to
make sure the system is safe during use and is operating
properly. You must also realize that in many test systems a
single fault, such as a software error, may output hazardous
signal levels even when the system indicates that there is no
hazard present.
It is important that you consider the following factors in your
system design and use:
• The international safety standard IEC 61010-1 denes
voltages as hazardous if they exceed 30 V
42.4 VPEAK or 60 V dc for equipment rated for dry
locations. Keithley Instruments products are only rated for
dry locations.
• Read and comply with the specications of all instruments
in the system. The overall allowed signal levels may be
constrained by the lowest rated instrument in the system.
For example, if you are using a 500 V power supply with
a 300 V dc rated switch, the maximum allowed voltage in
the system is 300 V dc.
• Cover the device under test (DUT) to protect the operator
from ying debris in the event of a system or DUT failure.
RMS and
• Make sure any test xture connected to the system
protects the operator from contact with hazardous
voltages, hot surfaces, and sharp objects. Use
shields, barriers, insulation, and safety interlocks to
accomplish this.
• Double-insulate all electrical connections that an operator
can touch. Double insulation ensures the operator is
still protected even if one insulation layer fails. Refer to
IEC 61010-1 for specic requirements.
• Make sure all connections are behind a locked cabinet
door or other barrier. This protects the system operator
from accidentally removing a connection by hand and
exposing hazardous voltages. Use high-reliability fail-safe
interlock switches to disconnect power sources when a
test xture cover is opened.
• Where possible, use automatic handlers so that operators
are not required to access the DUT or other potentially
hazardous areas.
• Provide training to all users of the system so that they
understand all potential hazards and know how to protect
themselves from injury.
• In many systems, during power up, the outputs may be in
an unknown state until they are properly initialized. Make
sure the design can tolerate this situation without causing
operator injury or hardware damage.
NOTE
To keep users safe, always read and follow all safety warnings
provided with each of the instruments in your system.
Install the instrument
The 4200A-SCS can be used on a bench or in a rack. See
the instructions that came with your rack-mount kit if you are
installing the 4200A-SCS in a rack.
Wiring the interlock
If you need voltages greater than ±40 V for testing, you
must add an interlock switch to the xture. This ensures
that hazardous voltages are not present when the exterior
enclosure of the xture is open. It also enables the
4200A-SCS to output higher voltages when the exterior
enclosure of the xture is closed.
When the safety interlock signal is asserted (the switch is
closed and the signal is connected to +12 V), all the voltage
ranges of the SMUs are functional. When the safety interlock
signal is not asserted (the switch is open), the 200 V range
on the SMUs is disabled, limiting the nominal output to
±40 V.
If you need voltages greater than ±40 V, you must also
connect the exterior of the test xture enclosure to protective
earth (safety ground). Take care to ensure that the wiring
(FORCE, GUARD, and SENSE) in the xture does not
electrically contact the exterior of the enclosure.
WARNING
The 4200A-SCS is provided with an interlock circuit
NOTE
that must be positively activated for the high-voltage
output to be enabled. The interlock facilitates safe
operation of the equipment in a test system. Bypassing
the interlock could expose the operator to hazardous
voltage that could result in personal injury or death.
Asserting the interlock allows the SMU and preamplier
terminals to become hazardous, exposing the user to
possible electrical shock that could result in personal
injury or death. SMU and preamplier terminals should
be considered hazardous even if the outputs are
programmed to be low voltage. Precautions must be
taken to prevent a shock hazard by surrounding the test
device and any unprotected leads (wiring) with double
insulation for 250 V, Category 0.
There are low-voltage and high-voltage test xtures for the
4200A-SCS. Low-voltage xtures, such as the 8101-PIV, are
intended for applications that are less than ±40 V. For these
applications, an interlock is not needed.
High-voltage test xtures can be used with applications that
are greater than ±40 V. The test xture has a safety interlock
switch connected to its lid. When the lid is closed, the
interlock circuit is closed (asserted), and SMU ±200 V ranges
are enabled.
Conversely, the interlock circuit is open (de-asserted) when
the lid is open, and the SMU ±200 V ranges are disabled.
High-voltage test xtures require extra precaution to ensure
there are no shock hazards.
For correct operation with the 4200A-SCS, the test xture
should have a normally open switch that is used for the
interlock. An open interlock condition occurs when the switch
is open.
For the examples shown in this quick start guide, you do not
need to use an interlock. The 4200A-SCS functions on all
current ranges and up to ±40 V without asserting the
interlock. When the interlock is not asserted, the maximum
voltage on the SMU and preamplier terminals is not
hazardous.
To connect the interlock cable:
NOTE
1. Connect one end of the supplied interlock cable to
the rear panel of the 4200A-SCS. The location of the
rear-panel interlock connector is shown in the following
graphic.
2. Connect the other end of the connector to the test xture.
Test connections
If you are testing discrete devices, you need a test xture
that is equipped with 3-lug triaxial connectors. The 8101-PIV
test xture that is included with the 4200A-SCS-PKC allows
the 4200A-SCS to be connected to a discrete device.
For connections to a probe station for wafer testing, see the
4200A-SCS Learning Center
The outer shield of the triaxial cables connects the 8101-PIV
to the 4200A chassis, which connects to common.
