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
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 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.
