Safety Precautions
This instrument is an IEC safety class 01 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.
“Handle with care.” (To avoid injury, death of personnel or damage to the
instrument, the operator must refer to the explanation in the User’s Manual or
Service Manual.)
Electric shock, danger
Alternating current
Both direct and alternating current
ON (power)
OFF (power)
ON (power) state
OFF (power) state
Grounding
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 WT3000 is a power measurement instrument that can measure parameters
such as voltage, current, and power. Do not use this instrument for anything
other than as a power 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 disable this protection by using an
extension cord without protective earth grounding.

vii
IM 760301-01E
•Connect the Protective Ground 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.
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.
•Do Not Remove the Covers or Disassemble or Alter the Instrument
Only qualified YOKOGAWA personnel 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 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.
•Measurement Category
This instrument is a measurement category II product. Do not use it for
measurement category III or IV measurements.
•Installation Location
• This instrument is designed to be used indoors. Do not install or use it outdoors.
• Install the instrument so that you can immediately remove the power cord if an
abnormal or dangerous condition occurs.
CAUTION
Operating Environment Limitations
This product is a Class A (for industrial environments) product. Operation of this
product in a residential area may cause radio interference in which case the
user will be required to correct the interference.
