Safety Precautions
Make sure to comply with the following safety precautions. Failure to comply may result in injury or death
(electric shock hazard).
• Power Supply
Before connecting the power cord, ensure that the power supply voltage matches the voltage rating for
the instrument, and that it is within the maximum rated voltage for the power cord itself.
• Power Cord and Plug (Desktop Type)
To prevent an 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 grounding terminal. Do not invalidate
protection by using an extension cord without protective grounding.
• Protective Grounding
Make sure to connect the protective grounding to prevent electric shock before turning ON the power.
• Necessity of Protective Grounding
Never cut off the internal or external protective grounding wire or disconnect the wiring of the protective
grounding terminal. Doing so poses a potential shock hazard.
• Defect of Protective Grounding
Do not operate the instrument when the protective grounding or the fuse might be defective. Also, make
sure to check them before operation.
• Fuse
To prevent fire, only use a fuse that has a rating (voltage, current, and type) that is specified by the
instrument. When replacing a fuse, turn OFF the power switch and unplug the power cord. Never short
the fuse holder.
• Do Not Operate in Explosive Atmosphere
Do not operate the instrument in the presence of flammable liquids or vapors. Operation of any electrical
instrument in such an environment constitutes a safety hazard.
• Do Not Remove Covers
Some areas inside the instrument have high voltages. Do not remove the cover if the power supply is
connected. The cover should be removed by YOKOGAWA's qualified personnel only.
