Connecting the Power Supply and Turning the
Power Switch ON/OFF
Before Connecting the Power
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 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 the possibility of
electric shock. Connect the power cord to a three-pin 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.
Connecting the Power Cord
1.
Check that the power switch is turned OFF.
2.
Connect the power cord plug to the power connector on the left side panel.
3.
Connect the plug on the other end of the power cord to the outlet that meets the
conditions below. The AC outlet must be of a 3-prong type with a protective
earth ground terminal.

1. The DL750/DL750P can use a 100-V or a 200-V system for the power supply. The maximum
rated voltage of the power cord varies depending on its type. Check that the voltage supplied
to the DL750/DL750P is less than or equal to the maximum rated voltage of the provided
power cord (see page Part 1:iv) before using it.
