SAFETY CONSIDERATIONS

GENERAL. This is a Safety Class 1 instrument (provided with terminal for connection to protective earth ground).

OPERATION. BEFORE APPLYING POWER verify that the product is set to match the available line voltage, the correct

line fuse is installed, and all safety precautions (see following warnings) are taken. In addition, note the instrument's external markings described under "Safety Symbols".

WARNING.

• Servicing instructions are for use by service-trained personnel. To avoid dangerous electrical shock, do not perform any

servicing unless you are qualified to do so.

• BEFORE SWITCHING ON THE INSTRUMENT, the protective earth terminal of the instrument must be connected to

the protective conductor of the (mains) power cord. The mains plug shall be inserted only in an outlet socket that is provided with a protective earth contact. This protective action must not be negated by the use of an extension cord (power cable) that is without a protective conductor (grounding). Grounding one conductor of a two-conductor outlet is not sufficient protection.

• If this instrument is to be energized via an auto-transformer (for voltage change), make sure the common terminal is

connected to the earth terminal of the power source.

• Any interruption of the protective (grounding) conductor (inside or outside the instrument), or disconnecting of the

protective earth terminal will cause a potential shock hazard that could result in personal injury.

• Whenever it is likely that the protective earth connection has been impaired, this instrument must be made inoperative

and be secured against any unintended operation.

• 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 this instrument in the presence of flammable gases or fumes.

• Do not install substitute parts or perform any unauthorized modification to this instrument.

• Some procedures described in this manual are performed with power supplied to the instrument while its protective

covers are removed. If contacted, the energy available at many points may result in personal injury.

• Any adjustment, maintenance, and repair of this instrument while it is opened and under voltage should be avoided as

much as possible. When this is unavoidable, such adjustment, maintenance, and repair should be carried out only by a skilled person who is aware of the hazard involved.

• Capacitors inside this instrument may hold a hazardous electrical charge even if the instrument has been disconnected

from its power source.

Revisions

Manual Revisions

This manual was written for AC Power Sources; that have the same serial prefixes (first part) as those listed on the title page and whose serial numbers (second part) are equal to or higher than those listed in the title page.

Introduction

Note 1) If the serial prefix of your unit is higher than that shown in the title page then the unit was made after

the publication of this manual and may have hardware and/or firmware differences not covered in this manual. If they are significant to the operation and/or servicing of the AC Power Source, those differences are documented in one or more Manual Change sheets included with this manual.

2) If the serial prefix on the unit; is lower than that shown on the title page, then the unit was made before the publication of this manual and can be different from that described here. Such differences are covered in “Appendix A - Manual Backdating Changes” in the User’s Manual.

Firmware Revisions

You can obtain the firmware revision number by either reading the integrated circuit label, or query the AC Power Source; using the GPIB *IDN query command (see "Chapter 3 -Troubleshooting" ).

Electrostatic Discharge

The power supply has components that can be damaged by ESD (electrostatic discharge). Failure to observe standard, antistatic practices can result in serious degradation of performance, even when an actual failure does not occur.

When working on the AC Power Source; observe all standard, antistatic work practices. These include, but are not limited to:

• working at a static-free station such as a table covered with static-dissipative laminate or with a conductive table mat

(Agilent P/N 9300-0797, or equivalent).

• using a conductive wrist strap, such as Agilent P/N 9300-0969 or 9300-0970.

• grounding all metal equipment at the station to a single common ground.

• connecting low-impedance test equipment to static-sensitive components only when those components have power

applied to them.

• removing power from the AC Power Source before removing or installing printed circuit boards .
