HP 8673G Safety Considerations

SAFETY CONSIDERATIONS

GENERAL

This product and related documentation must be reviewed for familiarization with safety markings and instructions before operation.

This product is a Safety Class I instrument (pro- vided with a protective earth terminal).

BEFORE APPLYING PDWER

Verify that the product is set to match the avail- able line voltage and the correct fuse is installed.

SAFETY EARTH GROUND

An uninterruptible safety earth ground must be provided from the main power sourceto the prod-

uct input wiring terminals, power cord, or sup- plied power cord set.

Any interruption of the protective (grounding) conductor (inside or outside the instrument) or disconnecting thepro- tectiweearth terminal will causeapoten- tial shock hazard that could result in personal injury. (Grounding one conduc- tor of a two conductor outlet is not suffi- cientprotection.) In addition, verify that a common ground exists between the unit under test and this instrumentprior to energizing either unit.

Whenever it is likely that theprotection has been impaired, the instrument must be made inoperative and be secured against any unintended operation.

If this instrument is to be energized via an auto-transformer (for voltage reduc- tion) make sure the common terminal is connected to neutral (that is, the grounded side of the mains supply).

Servicing instruction are for use by service-trained personnel only. To auoid dangerous electricshock, do not perform any servicing unless qualified to do so. Adjustments described in the manual are performed with power supplied to the instrument while protective covers

are removed. Energy available at many points may, if contacted, result in personal injury.

Capacitors inside the instrument may still be charged even if the instrument has been disconnectedfrom its source of SUPPlY.

For continued protection against fire hezard, replace the line fuse(s)only with 25OV fuse(s) of the same current rating and type (for example, normal blow, time delay, etc.) Do not use repaired fuses or short-circuited fuseholders.
