NOTICE
Read this manual before working with the product. For personal and system
safety, and for optimum product performance, ensure you thoroughly
understand the contents before installing, using, or maintaining this
product.
For equipment service or support needs, contact your local Emerson
Automation Solutions/Rosemount Tank Gauging representative.
Spare Parts
Any substitution of non-recognized spare parts may jeopardize safety.
Repair, e.g. substitution of components etc, may also jeopardize safety and
is under no circumstances allowed.
Rosemount Tank Radar AB will not take any responsibility for faults,
accidents, etc caused by non-recognized spare parts or any repair which is

CAUTION
Make sure that there is no water or snow on top of the lid when it is opened.
This may damage the electronics inside the housing.
CAUTION
Be careful when opening the lid in very low temperatures. High humidity and
temperatures far below the freezing point may cause the gasket to get stuck
to the lid. In that case you may use a heating fan to warm the housing in
order to release the gasket. Be careful not to use excess heat which may
damage the housing and electronics.
CAUTION
The products described in this document are NOT designed for nuclear-
qualified applications. Using non-nuclear qualified products in applications
that require nuclear-qualified hardware or products may cause inaccurate
readings. For information on Rosemount nuclear-qualified products, contact
your local Emerson Sales Representative.

•Use the equipment only as specified in this manual. Failure to do so may
impair the protection provided by the equipment.
•Do not perform any service other than those contained in this manual
unless you are qualified.
•Substitution of components may impair Intrinsic Safety.
Explosions could result in death or serious injury.
•Verify that the operating atmosphere of the transmitter is consistent
with the appropriate hazardous locations certifications.
•Do not remove the gauge cover in explosive atmospheres when the
circuit is alive.
High voltage that may be present on leads could cause electrical shock.
•Avoid contact with the leads and terminals.
•Ensure the mains power to the device is off and the lines to any other
external power source are disconnected or not powered while wiring the
device.
Electrical shock could cause death or serious injury.
•Use extreme caution when making contact with the leads and terminals.
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or

The Rosemount 2460 System Hub collects measurement data from field
devices and transmits the data to a host system. It also handles
communication from a host to the field devices.
The Rosemount 2460 supports a number of host communication interface
standards such as Ethernet, TRL2, RS485, and RS232. TRL2 and RS485 are
supported for field device communication also, as well as other standards
such as Enraf and Digital Current Loop (Whessoe).
