1 Safety

WARNING

• Failure to follow these installation guidelines could result in serious injury

or death.

• Installation and servicing instructions are for use by qualified personnel

only. Do not perform any servicing other than that contained in the
operating instructions, unless qualified.

• Rosemount Magnetic Flowmeters ordered with non-standard paint

options or non-metallic labels may be subject to electrostatic discharge.
To avoid electrostatic charge build-up, do not rub the flowmeter with a
dry cloth or clean with solvents.

• Verify that the operating environment of the sensor and transmitter is

consistent with the appropriate Agency Approval.

• If installed in an explosive atmosphere, verify that the device certification

and installation techniques are suitable for that particular environment.

• To prevent ignition of flammable or combustible atmosphere,

disconnect power before servicing circuits.

• Explosion hazard—Do not disconnect equipment when a flammable or

combustible atmosphere is present.

• Do not connect a Rosemount Transmitter to a non-Rosemount sensor

when installed in an “Ex” environment, explosive atmosphere, hazardous
area, or classified area.

• Follow national, local, and plant standards to properly earth ground the

transmitter and sensor. The earth ground must be separate from the
process reference ground.

CAUTION

• In cases where high voltage/high current are present near the meter

installation, ensure proper protection methods are followed to prevent
stray voltage/current from passing through the meter. Failure to
adequately protect the meter could result in damage to the transmitter
and lead to meter failure.

• Completely remove all electrical connections from both sensor and

transmitter prior to welding on the pipe. For maximum protection of the
sensor, consider removing it from the pipeline.

4 Rosemount™ 8712EM Transmitter with Foundation™ Fieldbus

May 2019 Quick Start Guide

3 Pre-Installation

Before installing the transmitter, there are several pre-installation steps that
should be completed to make the installation process easier:

• Set the hardware switches if necessary

• Consider mechanical, electrical, and environmental requirements

Note

Refer to the product reference manual for more detailed requirements.

Hardware switches

The electronics board is equipped with two user-selectable hardware
switches. These switches set the Simulate Enable and Transmitter Security.
The standard configuration for these switches when shipped from the
factory are as follows:

Table 3-1: Hardware switch default settings

Setting Factory configuration

Simulate enable Off

Transmitter security Off

In most cases, it is not necessary to change the setting of the hardware
switches. If the switch settings need to be changed, refer to the product
reference manual.

Be sure to identify any additional options and configurations that apply to
the installation. Keep a list of these options for consideration during the
installation and configuration procedures.

Mechanical considerations

The mounting site for the transmitter should provide enough room for
secure mounting, easy access to conduit entries, full opening of the
transmitter covers, and easy readability of the Display screen (if equipped).

Electrical considerations

Before making any electrical connections to the transmitter, consider
national, local, and plant electrical installation requirements. Be sure to have
the proper power supply, conduit, and other accessories necessary to
comply with these standards.

6 Rosemount™ 8712EM Transmitter with Foundation™ Fieldbus

May 2019 Quick Start Guide

The transmitter requires external power. Ensure access to a suitable power
source.

Table 3-2: Electrical data

Rosemount 8712E flow transmitter with FOUNDATION fieldbus

Power input AC power:

90–250VAC, 0.45A, 40VA

Standard DC power:
12–42VDC, 1.2A, 15W

Fieldbus Fieldbus segment requires a separate

9VDC to 32VDC power supply with a
power conditioner to decouple the
power supply output from the fieldbus
wiring segment.

Environmental considerations

To ensure maximum transmitter life, avoid extreme temperatures and
excessive vibration. Typical problem areas include the following:

• Tropical or desert installations in direct sunlight

• Outdoor installations in arctic climates

Remote mounted transmitters may be installed in the control room to
protect the electronics from the harsh environment and to provide easy
access for configuration or service.

Pipe mounting

1. Attach the saddle clamp to the pipe using the U-bolt mounting
hardware.

2. Attach the transmitter to the saddle clamp assembly with
appropriate fasteners.

Surface mounting

5 Wiring

5.1 Conduit entries and connections

Transmitter conduit entries ports are ½"-14NPT as standard, M20 conduit
connections will use an adapter. Conduit connections should be made in
accordance with national, local, and plant electrical codes. Unused conduit
entries should be sealed with the appropriate certified plugs. The plastic
shipping plugs do not provide ingress protection.

5.2 Conduit requirements

• For installations with an intrinsically safe electrode circuit, a separate

conduit for the coil cable and the electrode cable may be required. Refer
to the product reference manual.

• For installations with non-intrinsically safe electrode circuit, or when

using the combination cable, a single dedicated conduit run for the coil
drive and electrode cable between the sensor and the remote
transmitter may be acceptable. Removal of the barriers for intrinsic
safety isolation is permitted for non-intrinsically safe electrode
installations.

• Bundled cables from other equipment in a single conduit are likely to

create interference and noise in the system. See Figure 5-1.

• Electrode cables should not be run together in the same cable tray with

power cables.

• Output cables should not be run together with power cables.

• Select conduit size appropriate to feed cables through to the flowmeter.

Sensor to transmitter wiring

Cable kits are available as individual component cables or as a combination
coil/electrode cable. Remote cables can be ordered directly using the kit
numbers shown in Table 5-1, Table 5-2, and Table 5-3. Equivalent Alpha
cable part numbers are also provided as an alternative. To order cable,
specify length as quantity desired. Equal length of component cables is
required.
