Note
Grounding the transmitter via threaded conduit connection may not provide
sufficient ground.
Grounding - F
Signal wiring of the fieldbus segment can not be grounded. Grounding out
one of the signal wires may shut down the entire fieldbus segment.
Shield wire ground
To protect the fieldbus segment from noise, grounding techniques for shield
wire usually require a single grounding point for shield wire to avoid creating
a ground loop. The ground point shall be located at the power supply.
The devices designed for "daisy-chain" connection offer an isolated shield
loop-through terminal in order to enable a continuous shield throughout the
Tankbus network.
In order to avoid unintentional grounding points, the cable shield inside the
terminal compartment must be isolated.
3.3.3 Hazardous areas
When the Rosemount 5900S level gauge is installed in hazardous areas, local
regulations and specifications in applicable certificates must be observed.
Certificates for Rosemount Tank Gauging products, such as the Rosemount
5900, are available on
3.3.4 Power requirements
The Rosemount 5900S is powered over the intrinsically safe Tankbus by the
Rosemount 2410 Tank Hub. The 2410 feeds the intrinsically safe fieldbus
segment by acting as a FISCO power supply on the Tankbus.
When installed in a F
Tank Hub, the Rosemount 5900S is powered by the FF segment.
