Please note that the switch on the front panel of the instrument does not stop the
flow of power to the instrument.
If you need to turn off the power, unplug the instrument at the mains or remove the
power cable connector from the appliance coupler at the rear of the instrument. For
this reason, the power cable connection should be easily accessible - allowing you
to turn off the power quickly. If the instrument is in a cabinet, it must be disconnected
from the line power by the system's line power switch.
The power switch allows you to switch between stand-by mode and
power-on mode.
Figure 2 Power Switch
When the instrument is in stand-by mode, the Pwr LED is orange. When
the instrument is powered-on, the Pwr LED is green.
To avoid the possibility of injury or death, you must observe the following
precautions before switching on the instrument.
•
Insert the power cable plug only into a socket outlet provided with a protective
earth contact. Do not negate this protective action by using an extension cord
without a protective conductor.
•
Do not interrupt the protective earth connection intentionally.
The AC power requirements are summarized on the rear panel of the
instrument.
