Disconnecting from the Supply Source
The plug attached to the power cable (on the power outlet side or device side
of the cable) serves as the disconnecting device (device that cuts off the power
supply) of the E4980A/AL. When the power supply must be cut off to avoid
such danger as electric shock, pull out the power cable’s plug (on the power
outlet side or device side of the cable).
To allow this operation to be performed smoothly, be sure to follow the
guidelines in “Ensuring Adequate Free Space around the LCR meter for
Immediate Disconnection of the Power Cable in Case of Emergency” on
page 28.
When turning the power OFF under normal circumstances, always follow
the methods described in “Turning the Power ON and OFF” on page 29.
