Safely connect to instruments
Line voltage selection
The Model 2290-10 auto detects the input voltage and the input frequency. It operates from a 100 V
AC to 240 V AC power source that has a line frequency between 50 Hz and 60 Hz. Power
consumption is less than 80 Watts total.
The AC power connection on the rear panel provides the connection to the detachable power cord
and to a protective ground. Make sure that you always use an outlet that has a protective ground.
There are three versions of the Model 2290-10 to allow operation from a 100, 120, 220, or 240 V
nominal AC power source with a line frequency of 50 or 60 Hz. Before connecting the power cord to a
power source, verify that the line voltage selector card, located in the rear panel fuse holder, is set for
the correct AC line voltage.
This instrument may be damaged if operated with the line voltage selector set for the wrong AC line
voltage, or if the wrong fuse is installed.
Interlock circuit
An interlock circuit is provided on the rear panel of the instrument. This circuit must be closed to
enable the Model 2290-10 to produce output voltages. When the safety interlock signal is enabled,
the power supply is enable to output up to 10 kV. However, when the safety interlock signal is not
enabled, the output voltage is turned off.
The Model 2290-10 is provided with an interlock circuit that must be positively activated in
order for the high voltage output to be enabled. The interlock helps facilitate safe operation
of the equipment in a test system. Bypassing the interlock could expose the operator to
hazardous voltages that could result in personal injury or death.
