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.

• Potential electrostatic charging hazard: Rosemount Magnetic flow

meters 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 flow meter 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.

• 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.

• Shock hazard: Shut off power before servicing. Do not operate without

power compartment cover.

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.

November 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:

• Identify options and configurations that apply to your application

• Set the hardware switches if necessary

• Consider mechanical, electrical, and environmental requirements

Note

Refer to the product reference manual for more detailed requirements.

Identify options and configurations

The typical transmitter installation includes a device power connection, a
4-20mA output connection, and sensor coil and electrode connections.
Other applications may require one or more of the following configurations
or options:

• Pulse output

• Discrete input/discrete output

• HART multidrop configuration

The transmitter may have up to four user-selectable hardware switches.
These switches set the alarm mode, internal/external analog power,
internal/external pulse power, and transmitter security. The standard
configuration for these switches when shipped from the factory is as follows:

Table 3-1: Hardware switch default settings

Setting Factory configuration

Alarm mode High

Internal/external analog power Internal

Internal/external pulse power External

Transmitter security Off

The analog power switch and pulse power switches are not available when
ordered with intrinsically safe output, ordering code B.

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 Local Operator Interface (LOI)
screen (if equipped).
