Safety messages

Failure to follow these installation guidelines could result in death or serious injury. Only

qualified personnel should perform the installation.

WARNING

Explosion hazard that could result in death or serious injury.

Installation of this transmitter in an explosive environment must be in accordance with the

appropriate local, national, and international standards, codes, and practices. Review the

approvals section of this manual for any restrictions associated with a safe installation.

Before connecting a handheld communicator in an explosive atmosphere, ensure that the

instruments are installed in accordance with intrinsically safe or non-incendive field wiring

practices.

Magnetic hazard that can result in death or serious injury

This device contains magnets which could be harmful to pacemaker wearers.

Electrostatic hazard that can result in death or serious injury

Avoid contact with the leads and terminals. High voltage that may be present on leads can

cause electrical shock.

The power module may be replaced in a hazardous area. The power module has surface

resistivity greater than one gigaohm and must be properly installed in the wireless device

enclosure. Care must be taken during transportation to and from the point of installation to

prevent electrostatic charge build-up.

The polymer enclosure has surface resistivity greater than one gigaohm and must be

properly installed in the wireless device enclosure. Care must be taken during transportation

to and from the point of installation to prevent electrostatic charge build-up.

NOTICE

Shipping considerations for wireless products.

The unit was shipped to you without the power module installed. Remove the power module

prior to any re-shipping.

Primary lithium batteries are regulated in transportation by the U. S. Department of

Transportation, and are also covered by IATA (International Air Transport Association), ICAO

(International Civil Aviation Organization), and ADR (European Ground Transportation of

Dangerous Goods). It is the responsibility of the shipper to ensure compliance with these or

any other local requirements. Consult current regulations and requirements before shipping.

WARNING

Physical access

Unauthorized personnel may potentially cause significant damage to and/or

misconfiguration of end users’ equipment. This could be intentional or unintentional and

needs to be protected against.

Physical security is an important part of any security program and fundamental in protecting

your system. Restrict physical access by unauthorized personnel to protect end users’ assets.

This is true for all systems used within the facility.

2 Wireless considerations

2.1 Power up sequence

Verify the Wireless Gateway is installed and functioning properly

before any wireless field devices are powered. Install the Power

Module, SmartPower™ Solutions model number 701PBKKF into the

Rosemount 702 Wireless Discrete Transmitter to power the device.

Power up wireless devices in order of proximity from the Gateway,

beginning with the closest device, then working outward from the

Gateway. This results in a simpler and faster network formation.

Enable Active Advertising on the Gateway to ensure new devices are

able to join the network faster.

2.2 Antenna position

Position the antenna vertically, either straight up or straight down,

and approximately 3 ft. (1 m) from any large structure, building, or

conductive surface to allow for clear communication to other devices.

Figure 2-1: Antenna Position

2.3 Conduit entry

Upon installation, ensure each conduit entry is either sealed with

a conduit plug using approved thread sealant, or has an installed

conduit fitting or cable gland with appropriate threaded sealant.

Note

The conduit entries are threaded ½–14 NPT.

A. Conduit entry

2.4 Field Communicator connections

The power module must be installed before the Field Communicator

can interface with the Rosemount 702 Wireless Discrete Transmitter.

For HART® Wireless Transmitter communication via a Field

Communicator, a Rosemount 702 Wireless Device Dashboard (DD)

is required. To obtain the latest DD, visit the Field Communicator

System Software and Device Description site at: Emerson.com/Field-

Communicator. This transmitter uses the Black Power Module; Order

model number 701PBKKF.

3 Mounting the transmitter with a strap

3.1 Direct mount installation

Note

Do not employ direct mount installation when using tubing and

connectors such as Swagelok® fittings.

B. Float switch

Procedure

1. Install the switch according to standard installation practices

making sure to use thread sealant on all connections.

2. Using the threaded conduit entry, attach the Rosemount 702

housing to the switch.

3. Referring to the wiring diagram (see Reference information:

wiring switch inputs, output circuits, and leak sensors), attach

the switch wiring to the terminals.

4. Connect the Power Module.

Quick Start Guide 9

Note

Wireless devices should be powered up in order of proximity

from the Wireless Gateway, beginning with the closest device

to the Gateway. This will result in a simpler and faster network

formation.

5. Close the housing cover and tighten to safety specification.

Always ensure a proper seal so the metal touches metal, but

do not over tighten.

6. Position antenna vertically, either straight up or straight down.

The antenna should be approximately 3 ft. (0.91 m) from any

large structures or buildings, to allow clear communication to

other devices.
