WARNING
Power Supply
Ensure the source voltage matches the voltage of the power supply before turning
on the power.
Power Cord and Plug
To prevent an electric shock or fire, be sure to use the power supply cord supplied
by YOKOGAWA. The main power plug must be plugged in an outlet with protective
grounding terminal. Do not invalidate protection by using an extension cord without
protective grounding.
Protective Grounding
Make sure to connect the protective grounding 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 protective grounding terminal. Doing so poses a potential shock hazard.
Defect of Protective Grounding and Fuse
Do not operate the instrument when protective grounding or fuse might be
defective.
Fuse
To prevent a fire, make sure to use fuses with specified standard (current, voltage,
type). Before replacing the fuses, turn off the power and disconnect the power
source. Do not use a different fuse or short-circuit the fuse holder.
Do not Operate in an Explosive Atmosphere
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 with high voltage. 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.
Handling the CRT
This CRT is in conformity with the requirements specified in CSA and VDE
standards. However please avoid rough handling or jarring of the instrument to
prevent possible CRT implosion. Breakage of the CRT may cause a high velocity
scattering of glass fragments.
