Cable/conduit entries
The electronics housing has three entries for ½ - 14 NPT glands. Optional M20×1.5, minifast and eurofast
adapters are also available.
For remote mounting, the nut and sleeve on the Rosemount 2240S can be replaced with a M32 gland for
connection of temperature sensors/WLS.
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
It is recommended that a sealant of type PTFE is used to prevent water ingress and to enable future
removal of the plug/gland.
