IM 2560A-01EN
Ground the Instrument before Making External Connections
Securely connect the protective grounding before connecting to the target device or to an
external control unit. Before touching the target device, turn off this instrument and check that
there is no voltage or current being output.
Measurement Category
The measurement category of the 2560A terminals is Other (O). Do not use it for main power
supply circuits or circuits that fall under Measurement Categories II, III, and IV.
Install or Use the Instrument in Appropriate Locations
• Do not install or use the instrument outdoors or in locations subject to rain or water.
• Install the instrument so that you can immediately remove the power cord if an abnormal or
dangerous condition occurs.
Wiring Correctly
This instrument sources large voltage and current. If you do not connect the devices correctly,
not only will it damage the instrument or the target device, it may also lead to electric shock or
fire. Be careful when you connect the lead wires, and be sure to check the following points.
Before output (before turning on the output), check that:
• Lead wires are connected to the instrument’s output terminals correctly.
Check that output lead wires that should be connected to low voltage-current output
terminals (OUTPUT 1) are not connected to the high voltage output terminals or large
current output terminals.
• Lead wires are connected to the target device correctly.
Lead wires are not shorted because of wiring errors, broken insulation of lead wires,
unintended contact with conductive parts, and so on.
• The lead wires are fastened firmly to the terminals.
• There no problems with the terminals, such as the presence of foreign substances.
During output (do not touch the terminals or the connected lead wires when this instrument is
on), check that:
• There no problems with the terminals, such as the presence of foreign substances.
• The terminals are not abnormally hot.
The terminal connections may become loose over time. If this happens, heat may be
generated due to changes in contact resistance. Periodically check that the lead wires are
firmly connected to the terminals. Be sure to turn off both this instrument and the target
device before you check the connections.
After output (immediately after the output is turned off)
After you output a voltage or current, voltage may remain for some time even after you turn
the output off. This residual voltage may lead to electric shock. Do not touch the terminals
immediately after you turn the output off. The amount of time that voltage remains varies
depending on the target device.
CAUTION
Operating Environment Limitations
