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.

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.

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.
