Before connecting the power supply, first connect a DCN4-TB4 Open Type
Connector to the communications connector to convert it to a screw terminal
block.
When using a Repeater Unit, supply power through the BS+ and BS− termi-
nals of the Repeater Unit's PORT1 connector.
Connect a 24-VDC power supply to the Master Unit's communications power
supply connector (BS+ and BS−). This provides communications power to
each Slave Unit and Repeater Unit connected by round cable II or Flat Cable
I/II. Connect only one communications power supply for the trunk line. The
cable between the communications power supply and the communications
power supply connector must be no longer than 3 m.
When Repeater Units are used, communications power to sub-trunk lines is
supplied by the downstream port communications power supply connectors
(BS+ and BS−) of the Repeater Units. The cable between the communica-
tions power supply and the communications power supply connector must be
no longer than 3 m.
Note:
When using the UL standards, please
install a unit to restrict current between
