3.9 Connecting the Power Cord and Turning the
Power ON/OFF
When Using the Accessory Power Cord
DR232/DS400/DS600 (when using the accessory power cord)
Follow the warnings below to avoid electric shock or damaging the instrument.
WARNING
• Connect the power cord only after confirming that the voltage of the
power supply matches the rated electric power voltage for this
instrument.
• Connect the power cord after checking that the power switch of this
instrument is turned off.
• To prevent electric shock or fire, always use the power cord supplied by
Yokogawa.
• Always use protective grounding to prevent electric shock. Connect the
power cord of the instrument to a three-pole power outlet which has a
protective ground terminal.
Do not use the function grounding ( marked terminal) under the power
connecting part as the protective ground terminal.
• Never use an extension cord that does not have protective grounding,
otherwise the protection feature will be negated.
• An AC outlet (auxiliary for the DS400/DS600) should be used to supply
power to the DS400/DS600 using a power cable(DV400-051)
separately available. Do not use this AC outlet to supply power to the
other equipments nor use other cables for the power connection.
Otherwise, the current flowing through the AC outlet will exceed the
permissible current, thereby resulting in the fuse blowing, overheating
or burning may occur.
Connecting Procedure
1. Check that the power switch is turned off.
2. Connect the plug of the accessory power cord to the power connector.
3. Plug the other end of the power cord into a power outlet that satisfies the following conditions:
For DS400/DS600 in order to cut down on unnecessary radio interference, attach a clamp filter
(accessory) near the power cord plug as shown below. Make a loop with the power cord and
clamp it in the clamp filter.
Rated supply voltage : 100 to 240 V AC (free power supply),operating voltage: 90 to 250 V AC
Rated supply voltage frequency : 50/60 Hz
Power consumption :
DR232 ... About 130 VA max.
DS400 ... About 55 VA max.
DS600 ... About 70 VA max.
Use a three-pole power outlet provided with a protective ground terminal.
