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.
• 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 the possibility of electric shock or fire, be sure to use the power cord
for the instrument that was supplied by YOKOGAWA.
• Make sure to perform 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.
• 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.
1. Check that the power switch is turned OFF.
2. Connect the power cord plug to the power connector on the rear panel. Use the
power cord that came with the package.
3. 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.
