Wiring for Analog Inputs
Note
(1) Connect the shield to the FG terminal to prevent noise.
(2) When an input is not being used, short the + and – terminals.
(3) Separate wiring from power lines (AC power supply lines, high-voltage
lines, etc.)
(4) When there is noise in the power supply line, install a noise filter on the
input section and the power supply.
(5) Refer to the following information on open circuits when using voltage in-
puts.
