Safety Considerations

Model

GENERAL

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

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

BEFORE APPLYING POWER

Verify that the product is set to match the available line voltage and the correct fuse is installed.

SAFETY EARTH GROUND

An uninterruptible safety earth ground must be provided from the main power source to the prod- uct input wiring terminals, power cord, or supplied power cord set.

SAFETY SYMBOLS

A Instruction manual symbol: the product will be marked with this symbol when it is necessary for the user to refer to the instruction

manual (refer to Table of Contents). f Indicates hazardous voltages. 1,- Indicates earth (ground) terminal.

The WARNING sign denotes a hazard. It calls attention to a procedure, practice, or the like, which, if not cor-

rectly performed or adhered to, could result in per- sonal injury. Do not proceed beyond a WARNING sign until the indicated conditions are fully under- stood and met.

The CAUTION sign denotes a hazard. It calls attention to an operating procedure, practice, 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.

I WARNING 1

Interrupting the protective (grounding) conductor (inside or outside the instrument)or disconnecting the protective earth terminal will cause a potential shock hazard that could result in personal injury. (Grounding one conductor of a two conductor outlet is not sufficientprotection).

Whenever it is likely that the protection has been impaired, the instrument must be made inopera- tive and be secured against any unintended operation.

If this instrument is to be energized via an auto- transformer (for voltage reduction), make sure the common terminal is connected to the earth termi- nal of the power source.

Servicing instructions are for use by service-trained personnel only. To avoid dangerous electric shock, do not perform any servicing unless qualified to do so.

Adjustments described in the manual are per- formed with power supplied to the instrument while protective covers are removed. Energy avail- able at many points may, if contacted, result inper-

sonal injury.

Capacitors inside the instrument may still be charged even if the instrument has been discon- nected from its source of supply.

For continued protection against fire hazard, re- place the line fuse(s)only with 250V 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.
