Connecting the Power Supply
Before Connecting the Power
To prevent the possibility of electric shock and damage to the instrument, follow the
warnings below.
WARNING
• Before connecting the power cord, ensure that the source voltage matches the
rated supply voltage of the instrument and that it is within the maximum rated
voltage of the provided power cord.
• Connect the power cord after checking that the main power switch of the
instrument is turned OFF.
• To prevent the possibility of electric shock or fire, always use the power cord
supplied by YOKOGAWA.
• Make sure to perform protective grounding to prevent the possibility of electric
shock. Connect the power cord to a three-prong power outlet with a protective
earth terminal.
• Do not use an extension cord without protective earth ground. Otherwise, the
protection function will be compromised.
• Use an AC outlet that complies with the power cord provided and securely
connect the protective grounding. If such an AC outlet is unavailable and
protective grounding cannot be furnished, do not use the instrument.

Connect the other end of the cord to an outlet that meets the conditions below.
The AC outlet must be of a three-prong type with a protective earth ground
terminal.
