Wiring
Use the following wiring procedure for the Rosemount 2230:
1. Unscrew and remove all six screws at the front of the display.
2. Remove the cover carefully. Take care of the locking spring for the 
weather protection hatch, see “2230 Components” on page 2-2.
NOTE!
Do not disconnect the cables between the display front and the circuit board. 
Ensure that the compartment is protected against water in case of rain.
3. Run the Tankbus cable through the gland.
4. Connect the Tankbus wires to the X2 and X3 terminals as illustrated in 
Figure 3-5 on page 3-11. Ensure that the positive lead is connected to 
the terminal marked FB+ and the negative lead to the terminal marked 
FB-.
5. Connect the cable shield to the “Shield Loop Through” (X1) terminal.
6. If the 2230 display is the last device on the Tankbus, connect a jumper 
for the built-in termination. See “The Tankbus” on page 3-8 for more 
information on termination.
7. Replace the cover. Make sure that the sealing and the locking device for 
the weather protection hatch are placed in the correct positions.
8. Firmly tighten the six screws on the front cover.
NOTE!
Ensure that o-rings and seats are in good condition prior to mounting the 
cover in order to maintain the specified level of ingress protection. The same 
requirements apply for cable inlets and outlets (or plugs). Cables must be 
properly attached to the cable glands.
