Caution during Use

1. Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected accidents.

2. 24VDC power supply should be insulated and limited voltage/current or Class 2, SELV power
supply device.

3. Use only designated connector and do not apply excessive power when connecting or
disconnecting the connectors.

4. Keep away from high voltage lines or power lines to prevent inductive noise.
In case installing power line and input signal line closely, use line filter or varistor at power
line and shielded wire at input signal line.
Do not use near the equipment which generates strong magnetic force or high frequency
noise.

5. Do not connect or disconnect the USB cable or RS485 cable quickly and repeatedly while
communicating.
It may cause damage or malfunction of the product and PC.

6. After supplying power, connect with the communication output product. When disconnect,
communication output product first and power last.

7. When connecting multiple SCM-WF48 units to a PC, number of COM port goes up in
sequential order and it takes some time to identify and assign number of COM port.

8. When connecting the RS485 communication output product, connect the terminating
resistance (120Ω) at each end of the communication cable.

9. Use twist pair wire for RS485 communication. If not, use A(+) and B(-) cables in the same
length.

10. Use USB cable of designated standard, and do not use extension cable.

11. This unit may be used in the following environments.

Indoors (in the environment condition rated in 'Specifications')
