Safety precautions

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
warranty may be impaired.

The types of product users are:
Responsible body is the individual or group responsible for the use and maintenance of

equipment, for ensuring that the equipment is operated within
limits, 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 instrument. 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
properly, for example, setting the line vol
procedures are described in the user documentation. The procedures explicitly state if the
operator may perform them. Otherwise, they should be performed only by service personnel.

repair products. Only properly trained service personnel may perform installation and
service procedures.

Unless explicitly allowed in the specifi cations, operating manual, and instrument labels, do
not connect any instrument to mains.

Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on
cable connector jacks or test fi xtures. The American National Standards Institute (ANSI)

Operators of this product must be protected from electric shock at all times. The responsible
body must ensure that operators are prevented access and/or insulated from every
connection point. In some cases, connections must be exposed to potential human contact.
Product operators in these circumstances must be trained to protect themselves from the risk

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 connecting sources to switching cards, install protective devices to limit fault current and
voltage to the card.

Before operating an instrument, ensure that the line co

cracks, or breaks before each use.

When installing equipment where access to the main power cord is restricted, such as rack
mounting, a separate main input power disconnect device must be provided in close proximity
to the equipment and within easy reach of the operator.

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
levels are defi ned in the specifi cations and operating information and shown on the instrument
panels, test fi xture panels, and switching cards.

When fuses are used in a product, replace with the same type and rating for continued
protection against fi re hazard.

Chassis c

onnections must only be used as shield connections for measuring circuits, NOT as

protective earth (safety ground) connections.
If you are using a test fi xture, keep the lid closed while power is applied to the device under test.

Safe operation requires the use of a lid interlock.

If a screw is present, connect it to protective earth (safety ground) using the wire
recommended in the user documentation.

Before performing any maintenance, disconnect the line cord and all test cables.
To maintain protection from electric shock and fi re, replacement components in mains circuits

— including the power transformer, test leads, and input jacks — must be purchased from
Keithley. Standard fuses with applicable national safety approvals may be used if the rating and

replaced wi
be purchased from other suppliers as long as they are equivalent to the original component
(note that selected parts should be purchased only through Keithley to maintain accuracy
and functionality of the product). If you are unsure about the applicability of a replacement

Important test system safety information

This product is sold as a stand-alone instrument that may
become part of a system that could contain hazardous
voltages and energy sources. It is the responsibility of the
test system designer, integrator, 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 denes

voltages as hazardous if they exceed 30 V

42.4 V

or 60 VDC for equipment rated for dry

PEAK

locations. Keithley Instruments products are only rated for
dry locations.

• Read and comply with the specications 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 VDC rated switch, the maximum allowed voltage in
the system is 300 VDC.

RMS

and

• Cover the device under test (DUT) to protect the operator

from ying debris in the event of a system or DUT failure.

• 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 specic 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.
