3.4 Connecting to a Power Supply and Turning the Power Switch On and Off
Connecting the Power Cord
1.
Check that the power switch is off.
2.
Connect the power cord plug to the power inlet on the left side panel.
3.
Connect the other end of the cord to an outlet that meets the conditions below. Use the three-
prong power outlet equipped with a protective earth terminal.
Rated supply voltage* 100 to 120 VAC/200 to 240 VAC
Permitted supply voltage range 90 to 132 VAC/198 to 264 VAC
Rated supply voltage frequency 50/60 Hz
Permitted supply voltage frequency range 48 to 63 Hz
Maximum power consumption Approx. 200 VA max.
(This value is for reference. When the built-in printer is not
being used and there are 16 active channels provided by
eight high-speed 10 MS/s 12-bit isolation modules, the
maximum power consumption is 135 VA.)
* The instrument can use a 100 V or a 200 V power supply. The maximum rated voltage differs according
to the type of power cord. Check that the voltage supplied to the DL850E/DL850EV is less than or equal
to the maximum rated voltage of the provided power cord (see page iii) before using it.
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.
