9 CONNECTIONS
■ How to connect to FG terminal for INS-AX Series
INS-AX Series has a floating structure equipped with FG terminal and G terminal. The
function of these terminals and how to connect to them are e plained below:
FG terminal is GND potential for chassis.
INS-○○○AX has one FG terminal on the rear panel.
IJ-○○ has a total of 2 FG terminals (one on the front panel and one on the rear panel).
•FG terminal on the front panel of IJ-○○ is provided to connect the case of a plug
socket to the chassis of IJ-○○ automatically, when a plug socket bo is connected.
•FG terminal of the rear panel is provided to connect the chassis of INS-○○○AX
to that of IJ-○○. Make connection with the supplied GND cable.
When it is necessary to connect the chassis to the ground for safety, connect FG terminal
on the rear panel to the ground directly. It is supposed the ground plane, which serves as
a test environment, has been connected to the ground. However, connect FG terminal
directly to the ground. Namely, do not connect it to the ground plane.
E ample of connection
Plug socket box
FG terminal
Ground plane
G terminal is Signal GND for output pulses.
Connect G terminal to the ground plane that serves as a test environment. When a plug
socket bo is used, connect G terminal of the plug socket bo to the ground plane.
A common mode test and a normal mode test are available as test methods.
In case of a common mode test, G terminal becomes Signal Ground, which is connected
to the ground plane by connecting G terminal to the ground plane.
In case of a normal mode (interphase injection) test, Signal GND is separated from G
terminal and connected to one of power phases (R,S, T, N) in IJ-○○, while G terminal is
left connected to the ground plane.
(It is not necessary to disconnect G terminal from the ground plane in a normal mode
test. For INS-400 Series, on the other hand, it is necessary to disconnect G terminal.)
