Introduction
This manual contains information for servicing YOKOGAWA’s MV1000 and MV2000.
WARNING
This service manual is to be used by properly trained personnel only. To avoid
personal injury, do not perform any servicing unless you are qualified to do
so. Refer to the safety precautions prior to performing any servicing. Even if
servicing is carried out according to this service manual, or by qualified personnel,
YOKOGAWA assumes no responsibility for any result occurring from that servicing.
Safety Standards and EMC Standards
The MV conforms to IEC safety class I (provided with terminal for protective grounding),
Installation Category II, Measurement Category II (CAT II), and EN61326 (EMC
standard), class A (use in a commercial, industrial, or business environment).
The MV is designed for indoor use.
Safety Precautions
The general safety precautions described here must be observed during all phases of
operation. If the MV is used in a manner not described in this manual, the protection
provided by the MV may be impaired. Yokogawa Electric Corporation assumes no liability
for the customer’s failure to comply with these requirements.
WARNING
• Use the Correct Power Supply
Ensure that the source voltage matches the voltage of the power supply before
turning ON the power. In the case of a desktop type, ensure that it is within the
maximum rated voltage range of the provided power cord before connecting the
power cord.
• 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 earth grounding.
• Connect the Protective Grounding Terminal
Make sure to connect the protective grounding to prevent electric shock before
turning ON the power.
The power cord that comes with the desktop type 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 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.
Also, make sure to check them before operation.
