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 installation, 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 its specifi cations 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 category II or higher.
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) 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.
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.
