WARNING
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can
cause electrical shock.
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.
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.
6.2
Magnetic test point
A magnetic test point is marked on the side of the housing to allow a functional test of the
Rosemount 2120 in the overall system. By touching a magnet to the target, the output
from the level switch will change state while the magnet is present.
