Legal and Safety Information
Note the instrument's external markings described under "Safety Symbols". Only operate the product at the rated
mains voltage and phase as stipulated on the input label.
Ground the Instrument
This product is provided with protective earth terminals. To minimize shock hazard, the instrument must be connected
to the AC 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 pro-
tective earth terminal will cause a potential shock hazard that could result in injury or death.
External Voltage Sources
Do not connect voltage sources to the output of the power supply with voltage ratings that are greater than the nom-
inal voltage rating of the supply. Under no circumstances can you connect an external voltage with reversed polarity to
the output terminal. Equipment damage will result.
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
Only qualified, service-trained personnel who are aware of the hazards involved should remove instrument covers.
Always disconnect the power cable and any external circuits before removing the instrument cover.
Do Not Modify the Instrument
Do not install substitute parts or perform any unauthorized modification to the product. Return the product to an Agi-
lent Sales and Service Office for service and repair to ensure that safety features are maintained.
Fuses
The instrument contains an internal fuse, which is not customer accessible.
In Case of Damage
Instruments that are not functioning correctly, appear damaged or defective should be made inoperative and secured
against unintended operation until they can be repaired by qualified service personnel.
A WARNING notice denotes a hazard. It calls attention to an operating procedure, practice, or the like
that, if not correctly performed or adhered to, could result in personal injury or DEATH. Do not proceed
beyond a WARNING notice until the indicated conditions are fully understood and met.
