POINTS OF CAUTION
■HOT INSERTION/REMOVAL OF MODULES

without removing the power supply. However, replacing
multiple modules at once may greatly change line voltage
levels. We recommend that you replace them one by one.

Note 1: Remove CJC sensor for RTD or potentiometer input. The CJC sensor does not affect to DC voltage input.
Note 2: Be sure to eliminate noise as much as possible by e.g. using shielded cables. Ground the signal shield to
a most stable earth point in the environment.
Note 3: The temperature imbalance around the terminal affects greatly the cold junction compensation accuracy.
In order to minimize such imbalance, do not expose the input terminals directly to the wind from a cooling fan.
