Section 3. Installation
Figure 3-8 illustrates an example with a 2-in-1 version of the 5900S in a SIL
safety installation. A 4-wire cable is used to connect the Primary and
Secondary Tankbuses through the same cable entry. The SIL alarm wire is
connected through a separate cable entry. A junction box is used to provide
sufficient number of connections for the field devices to the Primary and
Secondary Tankbus.
