2240S Installation
4.4.9 Tankbus wiring
To connect a Rosemount 2240S:
1. Ensure that the power supply is switched off.
2. Loosen the four screws and remove the cover from the terminal compartment.
3. Run the Tankbus wires through the appropriate cable glands or conduits.
4. Connect the Tankbus wires to the X2 and X3 terminals as shown in Figure 4-6 on page 41 .
5. Connect the cable shield to the terminal marked X1.
6. In case the Rosemount 2240S is installed at the end of a Tankbus network, enable the termination by
using a jumper between terminals X3 and X4 as shown in Figure 4-6 on page 41 .
7. Use metal plugs to seal unused ports.
8. In order to prevent water from entering the terminal compartment, ensure the cover sealing is placed
in the correct position.
9. Attach and tighten the cover on the terminal compartment. Ensure that the cover is fully engaged to
meet explosion-proof requirements and to prevent water from entering the terminal compartment.
10.Tighten the conduit/cable glands. Note that adapters are required for M20 glands.
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.
