Precautions for Correct Use
Do not allow the wiring between the Gateway Unit and the power supply to exceed 3 m.
Selecting a DC Power Supply
The DC power supply must satisfy the following conditions.
Item
Output voltage
Output ripple
Output current
Isolation
For Slave Units with network power supply, the power for external I/O is also supplied from the
power supply connected to the Gateway Unit (through the Flat Cable). When determining the output
current of the power supply, always include the actual load currents and the current consumptions of
the external I/O.
Refer to documentation for each Slave Unit for information on Slave Unit current consumptions.

The capacity of the power supply must be equal to the sum of the
following current consumptions or greater.
•
Current consumptions of all Word Slave Units and Repeater Units
•
Current consumptions of all Bit Slave Units plus the current
consumptions of the external I/O
The output must be isolated from both the AC power supply and the
case ground.
