FB3000 RTU Instruction Manual
D301851X012
November 2023
24 Installation
Figure 2-17. External Power Connections
1
Input power from external power supply (power for RTU)
2
Loop power from external power (power for field devices)
Note
If your installation includes multiple chassis, wire power only to the left-most (base)
chassis.
Note
If your FB3000 does not power on, check that the polarity of the DC input voltage wiring
connections match Figure 2‐16. If you accidentally reversed the polarity, it triggers an
internal fuse and switch to protect the device from damage. Once the polarity is corrected,
the switch will reset automatically to allow for proper operation.
