Note
Use either of the methods shown below to connect the 24-V DC communica-
tions power supply to the trunk line. Refer to 2-4-7 Wiring the Communica-
tions Power Supply for wiring details.
1. The communications power supply can be connected through a T-branch
2. The communications power supply can be connected through a Power
When grounding the communications power supply to an acceptable ground
(100 Ω or less), connect the communications power supply’s V- and FG termi-
nals.
If an acceptable ground is not available, connecting the V- and FG terminals
may introduce noise into the network so we recommend against connecting
the terminals.
Use a separate power supply for DeviceNet communications. The power sup-
ply can be shared, however, if noise interference is not generated by the inter-
nal circuit power supply, Sensor power supply, or other source.
