2. Cautions
 Verify that the supply voltage variation is within the rating. Also, check the voltage variation at
the end terminal of the transmission route, since voltage drop occurs depending on the diam-
eter or the length of the transmission cable.
 If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.)
terminal of the power supply is connected to an actual ground.
 Do not use during the initial transient time (approx. 0.5sec.) after the power supply is switched
ON.
 Make sure to use an isolation transformer for the DC power supply. If an auto-transformer (sin-
gle winding transformer) is used, this product or the power supply may get damaged.
 In case a surge is generated in the power supply used, connect a surge absorber to the supply
and absorb the surge.
Power supply
 Do not run the wires together with high-voltage lines or power lines or put them in the same
raceway. This can cause malfunction due to induction.
 Make sure to carry out the installation and wiring in the power supply OFF condition.
 In order to reduce noise, make the wiring as short as possible.

In case of input, “0: Input OFF” or “1: Input ON” is read out in each bit.
