3-8
Take the following precautions before turning on the power supply. Failure to do so can
result in electric shock or damage to instruments.
• Before connecting the power cord, ensure that the power supply source voltage
matches the rated supply voltage of the instrument and that it is within the
maximum rated voltage of the provided power cord.
• Check that the instrument's power switch is OFF before connecting the power
cord.
• To prevent the possibility of electric shock or fire, always be sure to use the
power cord supplied for the instrument by YOKOGAWA.
• Make sure to implement protective earth grounding to prevent electric shock.
Connect the instrument's power cord into a three-prong electrical outlet with a
protective grounding terminal. The AC outlet must be of a three-prong type with
a protective earth ground terminal.
• Do not use an extension cord without protective earth ground. Otherwise, the
protection function will be compromised.
• Use an outlet that is compatible with the accessory power cord, and be sure to
connect protective grounding. Do not use the instrument if the power outlet does
not provide appropriate protective grounding.
The AQ6370B has a MAIN POWER switch for turning the main power ON/OFF, and a
POWER switch for starting and shutting down the instrument. The POWER switch is a
push-button switch; press once to turn it ON and press again to turn it OFF.
•
Confirm that the MAIN POWER switch on the rear panel of the instrument is OFF.
•
Make sure the voltage of the power outlet matches the instrument's supply
voltage.
•
Before replacing a fuse, always turn the MAIN POWER switch OFF and remove
the power cord from the power outlet.
Do not input a strong light source to the instrument when turning the power ON. If a
strong light source is input, the optical section can be damaged.
