Power Supply Wiring
Section 3-5
Using Repeater Units
Note
The I/O power supply to multi-power supply Slave Units may be a source of
noise depending on the connected devices. Even when supplying the commu-
nications power supply together to all Slave Units, use a separate I/O power
supply so that noise does not affect the network.
Using Round Cable II
or Flat Cable I/II
When round cable II or Flat Cable I/II is used, the Slave Unit communications
power is supplied through the Flat Cable I/II. There is no special wiring
required to provide the communications power supply to individual Slave
Units. The same communications power supply is shared for the entire trunk
line or sub-trunk line.
For Slave Units requiring an I/O power supply (i.e., multi-power supply Slave
Units), however, I/O power must be supplied separately.
