Before Connecting the Power Supply
WARNING
• Be sure to connect the protective grounding to prevent an electric shock
before turning on the power.
• Be sure to use the power supply cord provided by YOKOGAWA. The mains
power plug can only be plugged into an outlet with a protective grounding
terminal.
• Ensure that the source voltage matches the voltage of the power supply
before turning on the power.
• Connect the power cord only after having verified that the power switch is
turned OFF.
• Never use an extension cord without protective grounding wire since this
will invalidate the protection feature.
