2) Grounding the Analog Input Signal Cables
a) Connect the shield of the shielded twisted-pair wire to the "Shield" terminal of the
Module.
b) Use a wire of the following specifications to connect the Analog Input Module ground
terminal (FG) directly to the control panel ground terminal (E).
• Wire size: 1.5 mm
c) When connecting the ground terminals (FG) of several Analog Input Modules, also
use a wire of the above specifications to connect the Analog Input Module ground
terminal (FG) to the control panel ground terminal (E). Do not cross wires between
the Analog Input Module ground terminals.
Incorrect connection may make input signal unstable and cause malfunction.
3) Grounding the Analog Output Signal Cables
a) As a rule, ground the shield of the shielded twisted-pair wire to one point on the load
side. Better output characteristics, however, may be obtained by grounding it at one
point on the Module side. Ground according to the actual situation.
b) Ground the shield of the shielded twisted-pair wire to an unused terminal of the Ana-
log Output Module. Unused terminals are used as relay terminals.
c) Use a wire of the following specifications to connect the unused terminals, to which
the shield is grounded, directly to the control panel ground terminal (E).
• Wire size: 1.5 mm
d) When connecting the unused terminals of several Analog Output Modules, to which
the shields are grounded, also use a wire of the above specifications to connect
these unused terminals directly to the control panel ground terminal (E). Do not
cross wires between the Analog Output Module ground terminals.
Incorrect connection may make output signal unstable and cause malfunction.
