Wiring

Wiring the power supply
Connect the red conductor color (5V DC) to the positive side of the 5V DC power supply and connect black (0 V) to the
negative side. Carefully read the following important notes and wire the unit using the following connection example as a
reference.
WB1F
5V DC ±0.25 V
Black: Power supply -
Red: Power
Caution Caution
Do not reverse the power supply connections under any circumstances. Doing so may result in
damage.
z
Always turn off the WB1F's power supply before wiring the product.
z
Use the product within the rated power supply voltage range. Otherwise there is a risk of explosion or burn-
out.
z
When using this product in situations where it is not built into other equipment, do not use an integrated
power supply. Otherwise there is a risk of fire or electric shock.
z
The power supply reset time is 300 ms. Use the product 300 ms or later after turning on the power supply.
z
Avoid parallel wiring of the product's wires in the same conduit or duct with high voltage lines or power
lines (inverter power lines in particular) as this may cause malfunction or damage due to the effect of induc-
tion noise.
z
If the wires are long and when there is a risk of being affected by power sources or solenoids, independently
wire the product as a general rule.
z
For the RS-232 type, extend the cable with a AWG30 or thicker cable with due consideration the drop in the
power supply voltage.
If the total cable length exceeds 2.8 m, this may affect noise resistance, so fully evaluate this when using the
product.
For the RS-232 type, connect a shield of cable to ground or 0V when the communication performance is not
good by the noise environment.
z
For USB type, do not extend the connecting cable. Doing so may result in malfunction or damage.
z
Wiring external trigger input
The external trigger input is used to turn on the reading request.
The external trigger input operates as a non-voltage input or a voltage input (VIL: 1.0 V, VIH: 4.0 V-VCC).
Wire the I/O circuit by referring to the following I/O circuit connection example (dry contact).

Caution Caution
Mistakenly wiring the product may cause the internal circuit to be damaged.
