Safety Precautions
Failure to comply with the precautions below could lead to injury or death or
damage to the instrument.
WARNING
Use the Instrument Only for Its Intended Purpose
The GS820 is a signal source and measurement instrument that can output and
measure voltage and current. Do not use this instrument for anything other than as
a signal source and measurement instrument.
Check the Physical Appearance
Do not use the instrument if there is a problem with its physical appearance.
Use the Correct Power Supply
Beforeconnectingthepowercord,ensurethatthesourcevoltagematchesthe
rated supply voltage of the instrument and that it is within the maximum rated
voltage of the provided power cord.
Use the Correct Power Cord and Plug
To prevent the possibility of electric shock or fire, be sure to use the power cord
supplied by YOKOGAWA. The main power plug must be plugged into an outlet with
a protective earth terminal. Do not invalidate this protection by using an extension
cord without protective earth grounding. Additionally, do not use the power cord
supplied with this instrument with another instrument.
Do not use the power cord in a bundled condition. If you use a power plug with
foreign substance on it, insulation may be compromised by humidity or other
factors and may cause a fire. Clean the power plug regularly.
Connect the Protective Grounding Terminal
BesuretoconnecttheprotectiveearthtopreventelectricshockbeforeturningON
the power. The power cord that comes with the instrument is a three-prong type
power cord. Connect the power cord to a properly grounded three-prong outlet.
Do Not Impair the Protective Grounding
Nevercutofftheinternalorexternalprotectiveearthwireordisconnectthewiring
of the protective earth terminal. Doing so poses a potential shock hazard.
Do Not Use When the Protection Functions Are Defective
Beforeusingthisinstrument,checkthattheprotectionfunctions,suchasthe
protective grounding and fuse, are working properly. If you suspect a defect, do not
use the instrument.
Do Not Operate in Explosive Atmosphere
Do not operate the instrument in the presence of flammable gasses or vapors.
Operation in such an environment constitutes a safety hazard.
Do Not Remove the Covers or Disassemble or Alter the Instrument
Only qualified YOKOGAWApersonnel may remove the covers and disassemble or
alter the instrument. The inside of the instrument is dangerous because parts of it
have high voltages.
Ground the Instrument before Making External Connections
Securely connect the protective grounding before connecting to the target device or
toanexternalcontrolunit.Beforetouchingthetargetdevice,turnoffthisinstrument
and check that there is no voltage or current being output.
