1 The analog input is received through a twisted
pair shielded cable. This cable should be wired
separately from power lines or any other lines
which may induce electrical noise.
2 If a voltage ripple occurs during input, or there is
electrically induced noise on the external wiring,
connect a smoothing capacitor of 0.1 to 0.47µF,
25V.
3 If you are using current input, connect the V+ and
I+ terminals to each other.
4 If there is excessive electrical noise, connect the
FG frame ground terminal with the grounded
terminal on the FX-4AD.
5 Connect the ground terminal on the FX-4AD unit
with the grounded terminal on the base unit. Use
class 3 grounding on the base unit, if available.
