CONSIDERATIONS

Mechanical

2-2
Electrical shock can result in death or serious injury.
• Avoid contact with the leads and terminals.
Process leaks could result in death or serious injury.
• Install and tighten all four flange bolts before applying pressure.
• Do not attempt to loosen or remove flange bolts while the transmitter is
in service.
Replacement equipment or spare parts not approved by Rosemount Inc. for use
as spare parts could reduce the pressure retaining capabilities of the transmitter
and may render the instrument dangerous.
• Use only bolts supplied or sold by Rosemount Inc. as spare parts.
Improper assembly of manifolds to traditional flange can damage SuperModule
Platform.
• For safe assembly of manifold to traditional flange, bolts must break back
plane of flange web (i.e., bolt hole) but must not contact module housing.
Upper and lower unit labeling must match exactly to maintain hazardous
location approvals.
• When upgrading, it is imperative that approval codes match between the
SuperModule and the electronics housing.
Measurement performance depends upon proper installation of the
transmitter and impulse piping. Mount the transmitter close to the process and
use minimum piping to achieve best performance. Also, consider the need for
easy access, personnel safety, practical field calibration, and a suitable
transmitter environment. Install the transmitter to minimize vibration, shock,
and temperature fluctuation.
For a Rosemount 3051S transmitter assembled to a Rosemount 753R
Web-Based Monitoring indicator, detailed 753R installation instructions can
be found in the 753R Manual 00809-0100-4379.
IMPORTANT
Install the enclosed pipe plug (found in the box) in the unused conduit
opening. For straight threads, a minimum of 6 threads must be engaged. For
tapered threads, install the plug wrench-tight.
For material compatibility considerations, see document number
00816-0100-3045 on www.rosemount.com.
NOTE
For steam service or for applications with process temperatures greater than
the limits of the transmitter, do not blow down impulse piping through the
transmitter. Flush lines with the blocking valves closed and refill lines with
water before resuming measurement.
