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.
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
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 VDC rated switch, the maximum allowed voltage in the
system is 300 VDC.
• 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.
and 42.4 V
RMS
, or 60 VDC
PEAK
• Cover the device under test (DUT) to protect the operator
from ying debris in the event of a system or DUT failure.
• 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.
To keep users safe, always read and follow all safety warnings
provided with each of the instruments in your system.
Install the instrument
Connect line power
You can use a 2380-500-30 or 2380J-500-30 instrument on a
bench or in a rack. See the instructions that came with your
rack-mount kit if you are installing the programmable DC
electronic load in a rack.
To prevent damaging heat build-up and ensure specied
performance, make sure there is adequate ventilation and air ow
around the instrument to ensure proper cooling. Do not cover the
ventilation holes on the top, sides, or bottom of the instrument.
Make sure the instrument is positioned so that it is easy to reach
any disconnecting devices, such as the power cord and the
power switch.
Operating the instrument on an incorrect line voltage
may cause damage to the instrument, possibly voiding the
warranty.
The instrument operates at 100 V, 115 V, 220 V, or 230 V with
a frequency of 50 Hz or 60 Hz. Make sure that the AC line
voltage indicator in the center of the rear-panel power module
matches the AC line voltage in your facility, as shown in the
following gure.

Next steps
Connect line power
The power cord supplied with the Model 2380-500-30 or
2380J-500-30 instrument contains a separate protective
earth (safety ground) wire for use with grounded outlets.
When proper connections are made, the instrument chassis
is connected to power-line ground through the ground wire
in the power cord. In addition, a redundant protective earth
connection is provided through a screw on the rear panel.
This terminal should be connected to a known protective
earth. In the event of a failure, not using a properly grounded
protective earth and grounded outlet may result in personal
injury or death due to electric shock.
Do not replace detachable MAINS supply cords with
inadequately rated cords. Failure to use properly rated cords
may result in personal injury or death due to electric shock.
To connect line power:
1. Make sure the front-panel power switch is in the o (0) position.
2. On the rear panel, select the correct voltage level (230 V,
115 V, or 100 V).
3. Connect the socket of the supplied power cord to the power
connection on the rear panel.
4. Connect the plug of the power cord to a grounded AC outlet.
Turn on the instrument

terminals must be 26 AWG to 10 AWG.
The wire must be heavy enough not to overheat while
carrying the short‑circuit input current of the unit. Make sure
to meet the wiring requirements described above.
Two‑wire connections
Two‑wire connections are used for basic operations when
maximum precision is not required. Keep the wire as short
as possible to reduce wire resistance. If you want higher
measurement precision, use four‑wire remote sense connections.
