1 About this guide
This Quick Start Guide provides basic guidelines for the Rosemount 2110.
Refer to the Rosemount 2110 Reference Manual for more instructions. The
manual and this guide are also available electronically at
Emerson.com/Rosemount.
1.1 Safety messages
WARNING
Failure to follow safe installation and servicing guidelines could result in
death or serious injury.
Ensure the level switch is installed by qualified personnel and in accordance
with applicable code of practice.
Use the level switch only as specified in this manual. Failure to do so may
impair the protection provided by the level switch.
Repair, e.g. substitution of components, etc. may jeopardize safety and is
under no circumstances allowed.
WARNING
Explosions could result in death or serious injury.
The level switch must only be installed and operated in non-hazardous
(ordinary) locations.
WARNING
Electrical shock could cause death or serious injury.
Ensure the power to the level switch is off, and the lines to any other external
power source are disconnected or not powered while wiring the level switch.
Avoid contact with the leads and terminals. High voltage that may be
present on leads can cause electrical shock.
Ensure the wiring is suitable for the electrical current and the insulation is
suitable for the voltage, temperature, and environment.

WARNING
Process leaks could result in death or serious injury.
Ensure the level switch is handled carefully. If the process seal is damaged,
gas might escape from the vessel (tank) or pipe.
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users’ equipment. This could be intentional or
unintentional and needs to be protected against.
Physical security is an important part of any security program and
fundamental to protecting your system. Restrict physical access by
unauthorized personnel to protect end users’ assets. This is true for all
systems used within the facility.
CAUTION
Hot surfaces
The flange and process seal may be hot at high process temperatures. Allow
to cool before servicing.

3.1 Cable selection
Twisted-pairs and shielded wiring is recommended for environments with
high EMI (electromagnetic interference). Two wires can be safely connected
to each terminal screw. Maximum wire size is 15 AWG.
3.2 Cable glands/conduits
The cable gland is integrated in the four-position plug of the level switch. Do
not make any modifications to the level switch.
