1 Wireless considerations
1.1 Power up sequence
The Emerson Wireless Gateway (Gateway) should be installed and
functioning properly before power modules are installed in any wireless field
devices. Wireless field 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.
1.2 Antenna position
The antenna should be positioned vertically, and be approximately 3 ft. (1
m) from large structures or buildings to allow for clear communication to
other devices.
1.3 Mounting height
For optimal wireless coverage, the Gateway or remote antenna is ideally
mounted 15 to 25 ft. (4,6 to 7,6 m) above ground or 6 ft. (2 m) above
obstructions or major infrastructure.
1.4 Gateway redundancy
If the wireless Gateway was ordered with redundancy (Gateway Redundancy
code RD), refer to Appendix D in the Emerson Wireless Gateway Reference
Manual for additional installation instructions.

3 Initial connection and configuration
3.1 DeltaV™ ready
If the Gateway was ordered DeltaV Ready (Data Protocols Code 5), then skip
to Physical installation, and connect the Gateway to a DeltaV 10.3 or newer
control network.
3.2 Initial connection and configuration
To configure the Gateway, a local connection between a PC/laptop and the
Gateway needs to be established.
Powering the Gateway
Bench top power will be needed to power the Gateway by wiring a 24 VDC
(nominal) power source, with at least 250 mA, to the power terminals.

Note
Figure 3-1 depicts the terminal block of legacy Gateways prior to the
introduction of PoE capabilities. Figure 3-2 shows the terminal block
arrangement of a PoE version of the Gateway. If the Gateway will be
powered via the standard 24 volt power input terminals, and no PSE is
desired, it is not necessary to change the default settings of the PoE jumper
matrix.
Note
The Gateway enclosure case should always grounded in accordance with
national and local electrical codes. The most effective grounding method is a
direct connection to earth ground with minimal impedance.

Note
IEEE 802.3af-2003 PoE standard provides up to 15.4 W of DC power
(minimum 44 V DC and 350 mA) to each device. Only 12.95 W is assured to
be available at the powered device as some power is dissipated in the cable.
IEEE 802.3at-2009 PoE standard also known as “PoE+” or “PoE plus”,
provides up to 25.5 W of power. The 2009 standard prohibits a powered
device from using all four pairs for power.
For more information on PoE and frequently asked questions, reference the
Emerson Wireless Gateway white paper.
3.3 Establishing a connection
Note
For information on connecting a Windows 7 PC, see Technical Note
(document number 00840-0900-4420).
Procedure

4 Physical installation
4.1 Pipe mount
Tools needed:
•2-in. (51 mm) mounting pipe or mast
•Two 5/16-in. (7,9 mm) u-bolts supplied with Gateway
•1/2-in. socket-head wrench
For installing the Gateway with a pipe mount:
Procedure
1. Insert one u-bolt around the pipe, through the top mounting holes of
the Gateway enclosure, and through the washer plate.
2. Use a 1/2-in. socket-head wrench to fasten the nuts to the u-bolt.
3. Repeat Step 1 and Step 2 for the second u-bolt and lower mounting
holes.
4.1.1 Best practice
If the Gateway was ordered with output code 2, run a secondary Ethernet
cable when installing cable conduit from the Gateway to a convenient
indoor location to simplify future configuration changes.
4.2 Remote antenna (optional)
The remote antenna options provide flexibility for mounting the Gateway
based on wireless connectivity, lightning protection, and current work
practices.
September 2020 Quick Start Guide
Quick Start Guide 13

WARNING
When installing remote mount antennas for the Gateway, always use
established safety procedures to avoid falling or contact with high-power
electrical lines.
Install remote antenna components for the Gateway in compliance with
local and national electrical codes and use best practices for lightning
protection.
Before installing consult with the local area electrical inspector, electrical
officer, and work area supervisor.
The Gateway remote antenna option is specifically engineered to provide
installation flexibility while optimizing wireless performance and local
spectrum approvals. To maintain wireless performance and avoid non-
compliance with spectrum regulations, do not change the length of cable or
the antenna type.
If the supplied remote mount antenna kit is not installed per these
instructions, Emerson is not responsible for wireless performance or non-
compliance with spectrum regulations.
The remote mount antenna kit includes coaxial sealant for the cable
connections for the lightning arrestor and antenna.
Find a location where the remote antenna has optimal wireless
performance. Ideally this will be 15–25 ft. (4,6 to 7,6 m) above the ground or
6 ft. (2 m) above obstructions or major infrastructure. To install the remote
antenna use one of the following procedures:
4.3 Installation of WL2/WN2 option (outdoor applications)
Procedure
1. Mount the antenna on a 1.5 to 2-in. pipe mast using the supplied
mounting equipment.
2. Connect the lightning arrestor directly to the top of the Gateway.
3. Install the grounding lug, lock washer, and nut on top of the lightning
arrestor.
4. Connect the antenna to the lightning arrestor using the supplied
coaxial cable ensuring the drip loop is not closer than 1 ft. (0,3m)
from the lightning arrestor.
5. Use the coaxial sealant to seal each connection between the wireless
field device, lightning arrestor, cable, and antenna.
6. Ensure the mounting mast, lightning arrestor, and Gateway are
grounded according to local/national electrical code.
7. Place any spare lengths of coaxial cable in 12-in. (0,3 m) coils.

Note
Weather proofing is required! The remote mount antenna kit
includes coaxial sealant for the cable connections for the lightning
arrestor, antenna, and Gateway. The coaxial sealant must be applied
to guarantee performance of the wireless field network. See Figure
4-3 for details on applying weather proofing.

5 Connect to the host system
Procedure
1. Wire the Gateway’s Ethernet 1 (Primary) or Serial Output connection
to the Host System Network or Serial I/O.
2. For serial connections, connect A to A, B to B, making sure all
terminations are clean and secured to avoid wiring connection
problems.

5.1 Best practice
In accordance with Emerson WirelessHART® security guidelines, the Gateway
should be connected to the Host System via a LAN (Local Area Network) and
not a WAN (Wide Area Network).
Twisted shielded pair cable is generally used to wire the serial connection,
and it is standard practice to ground the shield on the serial host side leaving
the shield floating on the Gateway side. Insulate the shield to avoid
grounding issues.
5.2 Power
Power the Gateway as directed in Powering the Gateway.
