Make sure to comply with the following safety precautions. Not complying might
result in injury or death, or damage to the instrument.
WARNING
Power Supply
Before connecting the power cord, make sure that the power supply
voltage matches the voltage rating of the instrument and that it does
not exceed the maximum rated voltage of the power cord.
Power Cord and Plug
To prevent an electric shock or fire, be sure to use the power cord
supplied by YOKOGAWA. The main power plug must be plugged in an
outlet with a protective grounding terminal. Do not invalidate protection
by using an extension cord without protective grounding.
Protective Grounding
The protective grounding terminal must be connected to ground to
prevent an 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 and Fuse
Do not operate the instrument when the protective grounding or fuse
might be defective.
Do Not Operate Near Flammable Materials
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 Any Covers
There are some areas inside the instrument with high voltages. Do not
remove any cover if the power supply is connected. The cover should
be removed by qualified personnel only.
External Connection
To ground securely, connect the protective grounding before
connecting to measurement or control unit. Also, when touching the
circuit, turn off the power to the circuit and check that there is no
voltage being generated.
To prevent electric shock, connect the ground terminal of the probe or
input connector to the protective ground of the object under
measurement.
See below for operating environment limitations.
