WARNING
• Use the Correct Power Supply
Ensure that the source voltage matches the voltage of the
power supply before turning ON the power. In the case of a
desktop type, ensure that it is within the maximum rated voltage
range of the provided power cord before connecting the power
cord.
• Use the Correct Power Cord and Plug (Desktop Type)
To prevent 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 disable this protection by using an extension cord without
protective earth grounding.
The power cord is designed for use with this instrument. Do not
use the power cord with other instruments.
• Connect the Protective Grounding Terminal
Make sure to connect the protective grounding to prevent
electric shock before turning ON the power.
The power cord that comes with the desktop type 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 grounding wire
or disconnect the wiring of the protective grounding terminal.
Doing so invalidates the protective functions of the instrument
and poses a potential shock hazard.
• Do Not Operate with Defective Protective Grounding
Do not operate the instrument if the protective grounding might
be defective. Also, make sure to check them before operation.
• Do Not Operate in an Explosive Atmosphere
Do not operate the instrument in the presence of flammable
liquids or vapors. Operation in such an environment constitutes
a safety hazard.
Prolonged use in a highly dense corrosive gas (H 2 S, SOx, etc.)
will cause a malfunction.
• Do Not Remove Covers
The cover should be removed by YOKOGAWA’s qualified
personnel only. Opening the cover is dangerous, because some
areas inside the instrument have high voltages.
• Ground the Instrument before Making External Connections
Connect the protective grounding before connecting to the item
under measurement or control unit.
• Damage to the Protection
Operating the instrument in a manner not described in this
manual may damage the instrument’s protection.
