7. Power Cable Receptacle (to LINE)

The receptacle (outlet) to which the power cable is connected.
To connect the device to a power source (outlet), use the supplied
three-prong power cable with a ground conductor.
The plug attached to the power cable (on the power outlet side or device
side of the cable) serves as the E4980A/AL's disconnecting device (device
that cuts off the power supply). When the power supply must be cut off to
avoid such danger as electric shock, pull out the power cable plug (on the
power outlet side or device side of the cable). For the procedure for turning
off the power in normal use, see the description in
