2.3 Power Connection
This section describes the procedures for supplying power.
2.3.1 Power Requirements
For normal operation of the instrument, observe the power voltage range described below.
Voltage range Frequency
85 to 132 V 47.5 to 63 Hz
170 to 264 V 47.5 to 63 Hz
Changeover between 100 and 200 V systems is made automatically.
CAUTION
Supplying power exceeding the above range may result in electrical shock,
fire, failure, or malfunction.
2.3.2 Connecting the Power Cord
Check that the power switch on the front panel is turned off.
Insert the power plug into an outlet, and connect the other end to the power inlet on the rear panel. To ensure that the
instrument is earthed, always use the supplied 3-pin power cord, and insert the plug into an outlet with a earth terminal.
WARNING
If the power cord is connected without the instrument earthed, there is a risk of
receiving a fatal electric shock. In addition, the peripheral devices connected
to the instrument may be damaged.
When connecting to the power supply, DO NOT connect to an outlet without a
earth terminal. Also, avoid using electrical equipment such as an extension
cord or a transformer.
CAUTION
If an emergency arises causing the instrument to fail or malfunction, discon-
nect the instrument from the power supply by either turning off the power
switch on the front panel or by pulling out the power cord or the power inlet.
When installing the instrument, place the instrument so that an operator may
easily operate the main switch.
If the instrument is mounted in a rack, a power switch for the rack or a circuit
breaker may be used for power disconnection.
