NOTICE
Shipping considerations for wireless products (Lithium Batteries: Green Power Module, model
number 701PGNKF):
The unit was shipped to you without the Power Module installed. Remove the power module prior to
shipping the unit.
Each green power module contains one “D” size primary lithium-thionyl chloride battery. 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 ARD
(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.
Power module considerations (Green Power Module, model number 701PGNKF):
The green power module with the wireless unit contains one “D” size primary lithium-thionyl chloride
battery (model number 701PGNKF). Each battery contains approximately 5.0 grams of lithium. Under
normal conditions, the battery materials are self-contained and are not reactive as long as the batteries and
the pack integrity are maintained. Care should be taken to prevent thermal, electrical or mechanical
damage. Contacts should be protected to prevent premature discharge.
Battery hazards remain when cells are discharged.
Power modules should be stored in a clean and dry area. For maximum power module life, storage
temperature should not exceed 30 °C.

Quick Start Guide
1.0 Wireless considerations
1.1 Power up sequence
The power module should not be installed on any wireless device until the
Gateway is installed and functioning properly. Wireless devices should also be
powered up in order of proximity from the Gateway, beginning with the closest.
This will result in a simpler and faster network installation. Enable Active
Advertising on the Gateway to ensure new devices join the network faster. For
more information, see the Gateway Reference Manual.
1.2 Antenna position
The internal antenna is designed for multiple mounting orientations. The
transmitter should be mounted according to best practices for your temperature
measurement application. The transmitter should be approximately 3 ft. (1 m)
from any large structure or building to allow clear communication to other
devices.
1.3 Field Communicator connections
The power module must be installed in the device for the Field Communicator to
interface with the Rosemount 248 Wireless. The Field Communicator
connections are located on the green power module. To communicate to the
transmitter, begin by removing the power module cover. This will expose the
HART communication terminals located on the green power module. Next,
connect the Field Communicator leads to the COMM port connections on the
green power module.
This transmitter uses the green power module; order model number 701PGNKF.
The power module is keyed and can only be inserted in one orientation. Field
communication with this device requires a HART-based Field Communicator.
Refer to Figure 1 for instructions on connecting the Field Communicator to the
Rosemount 248 Wireless.
