Anritsu MT8801C - Protective Grounding

Section 2 Preparations Before Use

2.3.1 Protective grounding
(1) Grounding with 3-pole power outlet
The power supply polarity of the 3-pole (grounded, 2-pole type) matches that of
the 3-core power cord plug. Therefore, the MT8801C is connected to ground
potential when the power cord is connected to the plug. As a result, it is not
necessary to connect the FG terminal to ground.
(2) Grounding with conversion adapter
If a 3-pole power socket is not provided, use the 3-pole to 2-pole conversion
adapter as shown in the figure below. Connect the green wire protruding from
the 3 to 2 conversion adapter to ground.
