Keysight N774x Series
This is a Safety Class 1 instrument (provided with a protective earth
terminal) and has been manufactured and tested according to
international safety standards.
Before operation, you should review the instrument and manual for
safety markings and instructions. You must follow these to ensure safe
operation and to maintain the instrument in safe condition.
Some circuits are powered whenever the instrument is connected to the
AC power source. To disconnect from the line power, disconnect the
power cord either at the rear power inlet or at the AC line power source
(receptacle). One of these must always be accessible. If the instrument
is in a cabinet, it must be disconnected from the line power by the
system's line power switch.
To avoid hazardous electrical shock, do not perform electrical tests when there
are signs of shipping damage to any portion of the outer enclosure (covers,
panels, and so on).
The instrument is not designed for outdoor use. To prevent potential fire or shock
hazard, do not expose the instrument to rain or other excessive moisture.
The instrument complies with installation category II and can operate from the
single-phase AC power source that supplies between 100 V and 240 V at a frequency
in the range 50 to 60 Hz. The maximum voltage fluctuation is 10% of the nominal
supply voltage. The maximum power consumption is 60 VA with all options installed.
