Connecting the Power Supply and Turning the
Power Switch ON/OFF
Before Connecting the Power Supply
Make sure that you observe the following points before connecting the power. Failure to
do so may cause electric shock or damage to the instrument.
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 power switch of the instrument is
turned OFF.
• To prevent electric shock or fire, be sure to use the power cord for the
instrument that is supplied by YOKOGAWA.
• Make sure to provide protective earth grounding to prevent 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.
• If an AC outlet that matches the power cord provided is unavailable and
protective grounding cannot be furnished, do not use the instrument.
