Line cord
The Model 2290-5 uses a detachable, three-wire power cord for connection to the power source and
to a safety earth ground through a grounded AC outlet. Only use the power cord that's provided with
your instrument, or an equivalent adequately rated power cord.
The exposed metal parts of the instrument are connected to the outlet ground through the
line cord to provide protection against electrical shock. Always use an AC outlet that has a
properly connected safety ground.
Connect to other instruments
The rear panel SET/MON and I MON BNC jack shields are connected to chassis ground and the AC
power source ground using the power cord. Do not apply any voltage to the shields. The HIGH
VOLTAGE SHV port is also connected to chassis ground and cannot be floated above ground.
This unit contains hazardous voltages. Be absolutely certain that the high voltage is
completely discharged before removing or connecting the high-voltage cable. High-voltage
cables can store charge if they are disconnected from the supply while high voltage is
turned on, and can cause personal injury or death if not handled properly. Use only
connecting cables with a rated working voltage of 5 kV or higher (see the
Optional
accessories
section for more information).
Do not connect the high-voltage output to exposed circuitry. And load connected to the
high-voltage output should be enclosed in a metal shield that is connected to safety earth
ground using #18 AWG or larger wire.
If the instrument is used in a manner not specified by Keithley Instruments, the protection
provided by the equipment may be impaired.
