3.4 Connecting the Power Supply
Connecting the DC Power Supply to the DC Power Supply Model (/DC)
WARNING
• Connect the DC power cord after checking that the power switch of the
instrument is turned OFF. If you connect the power cord with the power switch
turned ON, sparks may be emitted and can lead to fire.
• To prevent the possibility of electric shock or fire, be sure to use a power cord
and power connector that YOKOGAWA specifies.
• Make sure to perform protective earth grounding to prevent electric shock.
CAUTION
• There is a polarity to the DC power connector. Check the polarity when making
a connection. If you have trouble connecting it, do not force it; check the
connector direction.
• To prevent shorting the power supply, remove the power cord from the power
supply when the power supply is not in use.
Creating the Power Cord
Create a power cord using the power connector that comes with the package. For the
power cord, use a cable that is between AWG12 (conductive cross-sectional area of 3.3
mm
2
) and AWG14 (conductive cross-sectional area of 2.1 mm
2
) with an outer diameter
less than or equal to 3.6 mm.
There are two types of terminal tips. Use the tip with a small diameter for the protective
grounding terminal.
