Keysight Technologies assumes no liability forcustomer’s failure to comply with these requirements.Product manuals may be provided on CD-ROM or in printed form. Printed manuals are anoption for many products. Manuals may also be available on the Web. Go towww.keysight.com and type the product model number in the Search field at the top ofthe page.NOTE Do not use this instrument in any manner not specified by the manufacturer. Theprotective features of this instrument may be impaired if it is used in a manner notspecified in the operation instructions.This instrument is an INDOOR USE product.This instrument complies with INSTALLATION CATEGORY II for mains input andINSTALLATION CATEGORY I for measurement input terminals, and POLLUTION DEGREE 2defined in IEC 61010-1.If an instrument is marked CAT I (IEC Measurement Category I), or it is not marked with ameasurement category, its measurement terminals must not be connected toline-voltage mains.Safety of any system incorporating the equipment is the responsibility of the assembler ofthe system.WARNING Hazardous voltage of up to the instrument’s maximum voltage may appear at High Force,Guard, and High Sense terminals if Interlock terminal is closed. Open the Interlockterminal when the High Force, Guard, and High Sense terminals are accessible. Voltageapplied to the terminals will be limited up to ±42 V.Do not work the interlock function intentionally in order to bring the output voltage to thesafe level. While the high voltage indicator is lit, the dangerous voltage by the outputvoltage or the residual charge appears on the measurement terminal.
