Safety Summary

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 elsewhere in this manual violates safety

standards of design, manufacture, and intended use of the instrument. Hewlett-Packard Company assumes no

liability for the customer's failure to comply with these requirements.

GENERAL

This product is a Safety Class 1 instrument (provided with a protective earth terminal). The protective features of

this product may be impaired if it is used in a manner not specified in the operation instructions.

Any LEDs used in this product are Class 1 LEDs as per IEC 825-1.

ENVIRONMENTAL CONDITIONS

This instrument is intended for indoor use in an installation category II, pollution degree 2 environment. It is

designed to operate at a maximum relative humidity of 95% and at altitudes of up to 2000 meters. Refer to the

specifications tables for the ac mains voltage requirements and ambient operating temperature range.

BEFORE APPLYING POWER

Verify that the product is set to match the available line voltage, the correct fuse is installed, and all safety

precautions are taken. Note the instrument's external markings described under "Safety Symbols".

GROUND THE INSTRUMENT

To minimize shock hazard, the instrument chassis and cover must be connected to an electrical ground. The

instrument must be connected to the ac power 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 protective earth terminal will cause a potential shock hazard that could result in

personal injury.

ATTENTION: Un circuit de terre continu est essentiel en vue du fonctionnement sécuritaire de l'appareil.

Ne jamais mettre l'appareil en marche lorsque le conducteur de mise … la terre est d‚branch‚.

FUSES

Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.) should be

used. Do not use repaired fuses or short-circuited fuseholders. To do so could cause a shock or fire hazard.

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

Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be

made only by qualified service personnel.

Instruments that appear damaged or defective should be made inoperative and secured against unintended

operation until they can be repaired by qualified service personnel.

WARNING The WARNING sign denotes a hazard. It calls attention to a procedure, practice, or the like,

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

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

Caution The CAUTION sign denotes a hazard. It calls attention to an operating procedure, or the like,

which, if not correctly performed or adhered to, could result in damage to or destruction of part

or all of the product. Do not proceed beyond a CAUTION sign until the indicated conditions

are fully understood and met.
