Wiring to Power
Wire the FB3000 through the bottom of the chassis.
The terminal blocks accept wiring 2mm in diameter
(12 AWG) or smaller. To connect the wire to the
removable block compression terminals:
Bare the end (6mm maximum) of the wire.
Insert the bared end of the wire into the clamp
beneath the termination screw.
Tighten the screw.
Expose a minimum of bare wire to prevent short circuits.
Allow some slack when making connections to prevent
strain.
Connect the power wiring. Review the power wiring
descriptions in Chapter 2 of the Emerson FB3000 RTU
Instruction Manual (part D301851X012).
Verify the hook-up polarity is correct.
To make DC power supply connections:
Remove the terminal block connector from the
socket.
Insert each bare wire end into its appropriate
connector and secure the wire (see Figure 9).
Plug the terminal block connector back into the
socket.
1 Input power from external power supply
(power for RTU)
2 Loop power from external power supply
(power for field devices)
