Quick Start Guide
1.3 Confirm HART Revision capability
If using HART-based control or asset management systems, confirm the HART
capability of those systems prior to transmitter installation. Not all systems are
capable of communicating with HART Revision 7 Protocol.
1.4 Confirm correct device driver
Verify the latest device driver (DD/DTM
™
) is loaded on your system to ensure
proper communication.

2.0 Handling
Proper handling of the Rosemount 520 is critical. To avoid damaging the
transmitter, avoid doing the following:
Lifting by the cable if the transmitter is mounted with fittings
Removing the protective diaphragm cap before installation
Applying pressure to the diaphragm using fingers, tools, or sharp objects
Using sharp objects to clean the diaphragm
Submerging or blocking the vent tube
Bending the cable within a radius of less than 90mm
3.0 Mount the transmitter
Note
All installation methods described in the following sections are grounded. If a different installation
method is used, the transmitter must be grounded to meet EMC and hazardous location
requirements.
3.1 Internal mounting
1. Secure the bracket to the tank wall.
2. Secure the transmitter by use of the provided spring. The spring is fitted into
the two holes in the bracket. The transmitter can be mounted and
dismounted without the use of tools.
3. Secure the transmitter cable to the tank wall.
Note
Emerson recommends protecting the cable by appropriate means to avoid the cable being
damaged from, for example, sloshing waves.
Emerson recommends installing the transmitter in locations with limited or no turbulence.
Emerson recommends avoiding this specific mounting method for service tanks due to challenges
associated with performing service and maintenance. Other mounting methods, such as pole
mounting, flexible rubber tube mounting and flexible PTFE tube mounting are recommended for
installation inside service tanks.
