Safety Precautions
This instrument is an IEC safety class I instrument (provided with a terminal for
protective earth grounding).
The general safety precautions described herein must be observed during all phases of
operation. If the instrument is used in a manner not specified in this manual, the
protection provided by the instrument may be impaired. Yokogawa Electric Corporation
assumes no liability for the customer’s failure to comply with these requirements.
The following symbols are used on this instrument.
Danger. Refer to the user’s manual. This symbol appears on dangerous
locations on the instrument which require special instructions for proper handling
or use. The same symbol appears in the corresponding place in the manual to
identify those instructions.
Alternating current

v
IM 703155-01E
Be sure to observe with the precautions below. Not complying might result in injury
or death.
WARNING
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 disable this protection by using an
extension cord without protective earth grounding.
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 Operate with Defective Protective Grounding or Fuse
Do not operate the instrument if the protective earth or fuse might be defective.
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 environments constitutes a safety hazard.
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
Securely connect the protective grounding before connecting to the item under
measurement or to an external control unit. If you are going to touch the circuit,
make sure to turn OFF the circuit and check that no voltage is present.
To prevent the possibility of electric shock or an accident, connect the ground of
the probe and input connector to the ground of the item being measured.
