Connecting the Power Supply

Before Connecting the Power Supply
To prevent electric shock and damage to the instrument, follow the warnings below.
• Make sure that the power supply voltage matches the instrument's rated supply voltage
and that it does not exceed the maximum voltage range specified for the power cord.
• Confirm that the instrument's power switch is off before you connect the power cord.
• To prevent fire and electric shock, only use a power cord supplied by YOKOGAWA.
• To avoid electric shock, be sure to ground the instrument. Connect the power cord to a
three-prong power outlet with a protective earth terminal.
• Do not use an ungrounded extension cord. Doing so renders the protective features of the
instrument ineffective.
• Use an outlet that complies with the power cord provided and securely connect the
protective grounding. If such an outlet is unavailable and protective grounding cannot be
furnished, do not use the instrument.
Connecting the Power Cord

2. Connect the instrument's power cord to the power inlet on the rear panel.
