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 protect the instrument and its users, refer to the explanation

Failure to comply with the precautions below could lead to injury or death.

WARNING

Use the Correct Power Supply

Make sure that the power supply voltage matches the WT500 rated supply voltage

and that it does not exceed the maximum voltage range specified for the power

cord.

Use the Correct Power Cord and Plug

To prevent fire and electric shock, use the power cord supplied by YOKOGAWA.

The main power plug must be plugged into an outlet with a protective earth

terminal. The earth protection will be nullified if you use an ungrounded extension

cord.

Connect to a Protective Earth Terminal

To prevent electric shock, be sure to connect to a protective earth terminal before

turning on the power. The power cord that comes with the instrument is a three-

prong 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

to the protective earth terminal. Doing so may result in electric shock or damage to

the instrument.

Do Not Operate with Defective Protective Grounding or Fuses

Do not operate the instrument if its protective grounding or one of its fuses might be

defective. Check the grounding and the fuses before operating the instrument.

Do Not Operate in an Explosive Atmosphere

Do not operate the instrument in the presence of flammable gasses or vapors.

Doing so is extremely dangerous.

Do Not Remove Covers

Only qualified YOKOGAWA personnel should remove the instrument’s covers. 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. Before touching a circuit, turn off its

power and check that it has no voltage.

Operating Environment Limitations

CAUTION

This is a class A instrument designed for an industrial environment. Operation of

this equipment in a residential area can cause radio interference, in which case

users will be required to correct the interference.
