Rosemount Model 1195/ProPlate/Mass ProPlate
2-8
Terminal Side of Electronics Housing
Wiring connections are made through the conduit openings on the top
side of the housing. The field terminal side is marked on the electronics
housing. Mount the Mass ProPlate so that the terminal side is
accessible. A 0.75-in. clearance is required for cover removal. Install a
conduit plug on the unused side of the conduit opening.
Circuit Side of Electronics Housing
The circuit compartment should not routinely need to be opened when
the unit is in service; however, provide 0.75-in. clearance if possible to
allow access.
ProPlate Orientation
Proper venting or draining must be considered when selecting a
ProPlate location.
For liquid service, mount the side drain/vent valve upward; this allows
gases to vent. For gas service, mount the drain/vent valve down to allow
any accumulated liquid to drain. In steam service, fill lines with water
to prevent contact of the live steam with the electronics; condensate
chambers are not needed because the volumetric displacement of the
electronics is negligible.
Hardware Installation Safety Messages
Instructions and procedures in this section may require special
precautions to ensure the safety of the personnel performing the
operations. Please refer to the following safety messages before
performing any operation in this section.
Explosions could result in death or serious injury:
• Do not remove the transmitter cover in explosive atmospheres when the circuit
is alive.
• Before connecting a HART-based communicator in an explosive atmosphere,
make sure the instruments in the loop are installed in accordance with
intrinsically safe or non-incendive field wiring practices.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
• Both transmitter covers must be fully engaged to meet explosion-proof
requirements.
Failure to follow these installation guidelines could result in death or serious injury:
• Make sure only qualified personnel perform the installation.
