Emerson Rosemount 2410 - Electrical Installation

3.4 Electrical installation
3.4.1 Cable entries
The Rosemount 2410 electronics housing has four ½ - 14 NPT and two ¾ - 14 NPT entries.
The 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
Thread sealing (PTFE) tape or paste on male threads of conduit is required to provide a
water/dust tight conduit seal and to meet the required degree of ingress protection as
well as to enable future removal of the plug/gland.
Note
NPT is a standard for tapered threads.Tightening torque is not given by the standard.
Common recommendation is to tighten the NPT gland by hand and then use a wrench to
tighten the NPT gland. Keep in mind that over tightening may be detrimental for the
sealing function or even damage the threads in the housing. Engage the gland with 5 to 6
threads. Note that there will be a number of threads left outside the housing as in Figure
3-1.
