Safety Notices

The following general safety precautions must be observed during all phases of operation of this instrument. Failure to

comply with these precautions or with specific warnings or instructions elsewhere in this manual violates safety stand-

ards of design, manufacture, and intended use of the instrument. Agilent Technologies assumes no liability of the cus-

tomer’s failure to comply with the requirements.

HAZARDOUS VOLTAGES All models generate voltages in excess of 60 VDC, with some

models rated at up to 1,500 VDC! Ensure that all instrument connections, load wiring,

and load connections are either insulated or covered so that no accidental contact

with lethal output voltages can occur.

General

The equipment is for industrial use. It is not applicable for IT mains supply systems.

Equipment operators are subject to all applicable safety regulations. Along with the warning and safety notices in this

manual, all relevant safety, accident prevention, and environmental regulations must also be followed. In particular,

the operators of the equipment:

lMust be informed of the relevant safety requirements.

lMust have read and understood the operating manual before using the equipment.

lMust use the designated and recommended safety equipment.

Do not use this product in any manner not specified by the manufacturer. The protective features of this product may

be impaired if it is used in a manner not specified in the operating instructions.

Environmental Conditions

Environmental condition are described under Common Characteristics.

Before Applying Power

Verify that all safety precautions are taken. All connections must be made with the unit turned off, and must be per-

formed by qualified personnel who are aware of the hazards involved. Improper actions can cause fatal injury as well as

equipment damage.

Legal and Safety Information

Note the instrument's external markings described under "Safety Symbols". Only operate the product at the rated

mains voltage and phase as stipulated on the input label.

Ground the Instrument

This product is provided with protective earth terminals. To minimize shock hazard, the instrument must be connected

to the AC mains through a grounded power cable, with the ground wire firmly connected to an electrical ground (safety

ground) at the power outlet. Any interruption of the protective (grounding) conductor or disconnection of the pro-

tective earth terminal will cause a potential shock hazard that could result in injury or death.

External Voltage Sources

Do not connect voltage sources to the output of the power supply with voltage ratings that are greater than the nom-

inal voltage rating of the supply. Under no circumstances can you connect an external voltage with reversed polarity to

the output terminal. Equipment damage will result.

Do Not Operate in an Explosive Atmosphere.

Do not operate the instrument in the presence of flammable gases or fumes.

Do Not Remove the Instrument Cover

Only qualified, service-trained personnel who are aware of the hazards involved should remove instrument covers.

Always disconnect the power cable and any external circuits before removing the instrument cover.

Do Not Modify the Instrument

Do not install substitute parts or perform any unauthorized modification to the product. Return the product to an Agi-

lent Sales and Service Office for service and repair to ensure that safety features are maintained.

Fuses

The instrument contains an internal fuse, which is not customer accessible.

In Case of Damage

Instruments that are not functioning correctly, appear damaged or defective should be made inoperative and secured

against unintended operation until they can be repaired by qualified service personnel.

A WARNING notice denotes a hazard. It calls attention to an operating procedure, practice, or the like

that, if not correctly performed or adhered to, could result in personal injury or DEATH. Do not proceed

beyond a WARNING notice until the indicated conditions are fully understood and met.
