N2779A Power Supply

Safety Precautions

This apparatus has been designed and tested in accordance

with IEC Publication 1010, Safety Requirements for

Measuring Apparatus, and has been supplied in a safe

condition. This is a Safety Class I instrument (provided with

terminal for protective earthing). Before applying power,

verify that the correct safety precautions are taken as

described in the following warnings. In addition, note the

external markings on the instrument as described in Table 1

on page 5.

WARNING If the instrument is damaged, or if it fails to operate according to the

characteristics in this manual, remove the power cord and contact

Agilent Technologies.

WARNING Before turning on the instrument, you must connect the protective earth

terminal of the instrument to the protective conductor of the (mains)

power cord. The mains plug shall only be inserted in a socket outlet

provided with a protective earth contact. You must not negate the

protective action by using an extension cord (power cable) without a

protective conductor (grounding). Grounding one conductor of a

two-conductor outlet is not sufficient protection.

WARNING If you energize this instrument by an auto transformer (for voltage

reduction or mains isolation), the common terminal must be connected

to the earth terminal of the power source.

WARNING Whenever it is likely that the ground protection is impaired, you must

make the instrument inoperative and secure it against any unintended

operation.

WARNING Service instructions are for trained service personnel. To avoid

dangerous electric shock, do not perform any service unless qualified to

do so. Do not attempt internal service or adjustment unless another

person, capable of rendering first aid and resuscitation, is present.
