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. Agilent Technologies Inc. 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.
All Light Emitting Diodes (LEDs) used in this product are 
Class 1 LEDs as per IEC 60825-1.
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 
80% 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. 
Ground the Instrument
To minimize shock hazard, the instrument chassis and 
cover must be connected to an electrical protective earth 
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.
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 fuse 
holders. 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.
