instances where care should be taken. These are listed below.
1. Twisted pair shielded cable should be used. This cable should also be isolated from
power lines, which could induce noise.
2. If noise (electrically induced) is present at the input, then a smoothing capacitor can
be used. The rating of which should be 0.1–0.47 m F.
3. You MUST when using a current input, connect terminals Vþ to Iþ.
4. If there is excessive noise, connect the FG terminal with the electrically grounded
terminal on the FX2N-4AD.
5. Connect the ground terminal on the FX2N-4AD uni t to the ground ...
