Yokogawa Button Operated MV2000 - Manual (Page 7)

WARNING
• Use the Correct Power Supply
Ensure that the source voltage matches the voltage of the power supply before turning the power ON.
• Use the Correct Power Cord and Plug
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 ground terminal. Do not disable this
protection by using an extension cord without protective grounding.
The power cord and the power cord for the AC adapter are designed for use with this instrument. Do not
use them with other instruments.
• Connect the Protective Grounding Terminal
Make sure to connect the protective grounding before turning the power ON, to prevent electric shock.
The power cord that comes with the desktop type is a three-pronged 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. Make sure to check it
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 the control unit.
• Damage to Safety Features
Operating the instrument in a manner not described in this manual may damage the instrument’s safety
features.
• Because the electrolyte solution inside the battery is alkaline, harm can be done to the clothes or skin, if
the battery leaks or explodes and the solution comes in contact. If the electrolyte solution enters the eye,
it can cause blindness. In such case, do not rub the eye. Rinse thoroughly with water and immediately
consult your eye doctor.
• To prevent the possibility of shorting the recharge circuit, electric shock, and accidents when replacing
the battery box, always turn OFF the power to the MV1000 and remove the AC adapter power cord from
the outlet.
• Only use the battery box from YOKOGAWA (B8805HA).
• Do not leave the battery in direct sunlight, inside a hot vehicle, or near fire. This can cause leakage or
lower the performance and life of the battery.
• Do not disassemble or modify the battery. This can compromise the protection function provided by the
battery and cause excessive heating and explosions.
• Do not short the battery connectors. You can receive burns from the generated heat.
• Do not throw the battery box into fire or apply heat to it. This can cause dangerous explosions or
spraying of the electrolytes.
• Do not throw the batterybox or apply strong shock to it. This can cause leaks, excessive heating, and
explosions.
