Warning
• Be sure to use the s12 VDC power cable supplied with the product.
• Make sure of the polarities in connecting the +12 VDC power cable. Otherwise, it may
cause not only product trouble, but smoke and a fire.
• Do not apply 100 VAC to the +12 VDC power cable by mistake. Otherwise, it may cause
smoke or a fire.
Caution
• Use a separate power source to supply power to the 12 VDC power connector CN2 on each
Ethernet module. In cases where it is not possible to use separate power sources, wire the
power cable in such a way that each Ethernet module can be separately switched off.
• Use a +12 VDC power supply with a protective circuit.
