3 Installation considerations

3.1 General considerations

When finding an appropriate location on the tank for a Rosemount 5900S Radar Level Gauge, the conditions of the tank must be carefully considered. The gauge should be installed so that the influence of disturbing objects is kept to a minimum, preferably outside the radar signal beam.
Ensure that the Rosemount 5900S is installed such that it is not exposed to higher pressure and temperature than specified.
It is the responsibility of the user to ensure that the device meets the specific inside tank installation requirements such as:
• chemical compatibility of wetted materials
• design/operation pressure and temperature
For a complete specification of the 5900S device to be installed, you can identify the model code on the attached antenna label and match with ordering information data.
Ensure that environmental conditions are within specified limits.
Do not install the Rosemount 5900S in non-intended applications, for example environments where it may be exposed to extremely intense magnetic fields or extreme weather conditions.
Antennas with plastic surfaces and painted surface, may under certain extreme conditions generate an ignition-capable level of electrostatic charge. When installing in hazardous areas ensure using tools, cleaning material etc. which can not generate electrostatic charge.
See the Rosemount 5900S Reference Manual for more information.

3.2 Parabolic antenna requirements

3.2.1 Inclination

The inclination of the Rosemount 5900S with Parabolic Antenna should not exceed 1.5 ° towards the center of the tank. For products with high condensation such as bitumen/asphalt applications, the radar beam should be directed vertically without any inclination.
Figure 3-1: Maximum Inclination with Parabolic Antenna
A. Maximum inclination 1.5°

3.2.2 Flange requirements

The tank flange has to meet the following inclination requirements (see
Figure 3-2) in order to allow proper adjustment of the antenna:
• maximum 4.5° away from the tank wall
• maximum of 2° towards the tank wall
• in case the nozzle inclination exceeds the recommended values, you may
use the welded flange ball which can be mounted at a maximum angle of 17°
60 mm (2.4 in.)
< 17°

3.2.3 Nozzle and free space requirements

When installing the Rosemount 5900S with parabolic antenna on a Ø 20" nozzle, consider the following recommendations.
Obstacles (construction bars, pipes larger than Ø 2", etc.) within the 10° wide radar beam are generally not accepted, as these may result in disturbing echoes. However, in most cases a smooth tank wall or small objects will not have any significant influence.

3.3 Electrical requirements

3.3.1 Cable/conduit entries

The electronics housing has two entries for ½ - 14 NPT. Optional M20×1.5, minifast and eurofast adapters are also available. The connections must be made in accordance with local or plant electrical codes.
Make sure that unused ports are properly sealed to prevent moisture or other contamination from entering the terminal block compartment of the electronics housing.
Note
Use the enclosed metal plugs to seal unused ports. The plastic plugs mounted at delivery are not sufficient as seal!
Note
Thread sealing (PTFE) tape or paste on male threads of conduit is required to provide a water/dust tight conduit seal and to meet the required degree of ingress protection as well as to enable future removal of the plug/gland.
NPT is a standard for tapered threads. Engage the gland with 5 to 6 threads. Note that there will be a number of threads left outside the housing as illustrated below.
Figure 3-5: Cable Entry with NPT Threaded Gland
A. The NPT threaded gland leaves a number of threads outside the housing
Ensure that glands for the cable entries meet requirements for IP class 66 and 67.

3.3.2 Grounding

The housing should always be grounded in accordance with national and local electrical codes. Failure to do so may impair the protection provided by the equipment. The most effective grounding method is direct connection to earth ground with minimal impedance.
There are three grounding screw connections provided. Two are located inside the terminal compartment of the housing and the third is located on
the housing. The internal ground screws are identified by a ground symbol:
.
Note
Grounding the transmitter via threaded conduit connection may not provide sufficient ground.
Grounding - FOUNDATION™ Fieldbus
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 Emerson.com/Rosemount Tank Gauging.

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 FOUNDATION Fieldbus system without a Rosemount 2410 Tank Hub, the Rosemount 5900S is powered by the FF segment.
