Installation precautions
Observe the following saf ety preca uti ons when installing instruments.
Turn off instrument power and unplug all ca bles before installing an instrument in a rack.
Failure to remove power before installing may cause personal injury or death from electrical
shock.
Heat sources should be mounted away from the instrument, its cabling, and its accessories, with
sufficient space provided between the instrument and heat source for airflow and cooling.
To prevent damaging heat build-up and ensure specified performance, make sure there is adequate
ventilation and airflow around the instrument to ensure proper cooling. Do not cover the ventilation
holes on the top, sides, or bottom of the instrument.
Cabinet preparati on
The rack mount kit requires a 4U slot in the cabinet because of the added vent panel. 1U is a
standard vertical spacing that is equal to 4.45 cm (about 1.75 in).
To prepare the rack for installation:
1. Select a location in the cabinet rack.
2. Take steps to make it easier to manipulate and install the instrument:
• Clear as much space as possible around the selected cabinet rack location.
• If practical, remove the cabinet sides from the rack.

Install the cage nuts
To install the cage nuts on the rack rails and the support shelves for the instrument:
1. Use the vent panel as a guide, mark holes for the selected installation location (eight places total).
2. Install the cage nuts (1) in the backside of each rail hole (2) where marked in step 1. To install a cage nut, if
you are using a cage nut installation tool, place the bottom lip of the nut so it rests in the rail hole. Grab the
top lip of the nut and pull (3) until the nut snaps in place. Repeat for each cage nut.

Safety precaut ions
The following safety precautions should be observed befor e usin g this produ ct and any ass ocia ted ins trum ent a tion . Alt ho ugh
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 installation, operation, and maintenance information carefully before using the
product. Refer to the user documentation for complete product specifications.
If the product is used in a manner not specified, 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 its specifications and operating 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
voltage or replacing consumable materials. Maintenance 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.
Service personnel are trained to work on live circuits, perform safe installations, and repair products. Only properly trained
service personnel may perform installation and service procedures.
Keithley Instruments products are designed for use with electrical signals that are measurement, control, and data I/O
connections, with low transient overvoltages, and must not be directly connected to mains voltage or to voltage sources with high
transient overvoltages. Measurement Category II (as referenced in IEC 60664) connections require protection for high transient
overvoltages often associated with local AC mains connections. Certain Keithley Instruments measuring instruments may be
connected to mains. These instruments will be marked as cat egory II or higher.
Unless explicitly allowed in the specifications, 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
fixtures. The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than
30 V RMS, 42.4 V peak, or 60 VDC are present. A good safety practice is to expect that hazardous voltage is present in any
unknown circuit before measuring.
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 of electric shock. If
the circuit is capable of operating at or above 1000 V, no conductive part of the circuit may be exposed.
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 jumpers, 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.
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 specified in the 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 defined in the
specifications and operating information and shown on the instrument panels, test fixture panels, and switching cards.
Chassis connections must only be used as shield connections for measuring circuits, NOT as protective earth (safety ground)
connections.
The WARNING heading in the user documentation explains dangers that might result in personal injury or death. Always read
the associated information very carefully before performing the indicated procedure.

The CAUTION heading in the user documentation explains h az ards that coul d dama ge th e instr ume nt. Su ch damage may
invalidate the warranty.
The CAUTION heading with the
injury or damage the instrument. Always read the associated information very carefully before performing the indicated
procedure. Damage to the instrument 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 Instruments. Standard fuses with applicable national
safety approvals may be used if the rating and type are the same. The detachable mains power cord provided with the
instrument may only be replaced with a similarly rated power cord. Other components that are not safety-rela ted may 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 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.
Unless otherwise noted in product-specific liter atur e , Keit hle y Instrument s instr ume nt s are desi gne d to operate indoors only, in
the following environment: Altitude at or below 2,000 m (6,562 ft); temperature 0 °C to 50 °C (32 °F to 122 °F); and pollution
degree 1 or 2.
To clean an instrument, use a cloth dampened with deionized water 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. Products that
consist of a circuit board with no case or chassis (e.g., a data acquisition board for installation into a computer) should never
require cleaning if handled according to instructions. If the board becomes contaminated and operation is affected, the board
should be returned to the factory for proper cleaning/servicing.
