STEP 4: MOUNT AND CONNECT THE GATEWAY
Integral Antenna with the 1420 on a Mast
The optimal installation of the 1420 Wireless Gateway is
on a pole approximately 1.8 meters above the top of the
exterior wall of a building. The following hardware and
tools are needed:
• Pipe mount with holes spaced 3.06 inches (78 mm)
apart horizontally and 11.15 inches (283 mm) apart
vertically.
• Two 3.06 inch (78 mm) by 5/16 inch U-bolts
• 1/2 inch wrench
Mount the gateway by doing the following:
1. Insert one U-bolt around the pipe and through the
top mounting holes of the pipe mount and the 1420,
and another U-bolt through the bottom mounting
holes of the pipe mount and the 1420.
2. Using a 1/2 inch socket-head wrench, fasten the nuts
to the U-bolts and tighten.
BEST PRACTICE
When mounting outside, best practice is to run the
Serial or primary Ethernet cable (P1) directly to the
Information System. Use conduit and/or strain relief
as necessary.
BEST PRACTICE
When installing cable/conduit, run an ethernet
connection from 1420 port P2 to a convenient
location indoors (if the 1420 was ordered with
Output Code 2). This will simplify future
configuration changes.

STEP 4 CONTINUED...
Remote Antenna (Optional)
The remote antenna options provide flexibility for mounting the Gateway based on wireless
connectivity, lightning protection, and current work practices.
WARNING
When installing a remote mount antenna for the Smart Wireless Gateway, use
established safety procedures to avoid falling or to avoid contacting high-power electrical
lines.
Install remote antenna components for the Smart Wireless gateway in compliance with
local and national electrical codes and use best practices for lightning protection.
Before installation, consult with the local area electrical inspector, electrical officer, and
work area supervisor.
The Smart Wireless Gateway remote antenna options are specifically engineered to
provide installation flexibility while optimizing wireless performance and maintaining local
spectrum approvals. Each remote antenna kit contains 50 ft. (15,2 m) of LMR-400 coaxial
cable, and a high-gain antenna. To maintain wireless performance and avoid
non-compliance with local spectrum regulations, do not change the length or type of
coaxial cable, or the antenna type.
If the remote antenna kit as specified is not used in this document, Emerson Process
Management is not responsible for wireless performance, or non-compliance with local
spectrum regulations.
Remote mount antenna kits include weather proof tape for use on the cable connections,
and a mounting kit for the lightning arrestor and antenna. The following diagram and table
describe each remote antenna kit option.

NOTE
The coaxial cables on the remote antenna options WL3 and WL4 are interchangeable

The remote antenna should be located for optimal wireless performance. Ideally, 15 - 25 ft.
(4,6 - 7,6 m) above the ground or 6 ft. (2 m) above obstructions or major infrastructure.
Installation of the WL2 Option:
1. Mount the antenna on a 2-in. (0.05 m) pipe mast using the supplied equipment.
2. Attach the lightning arrestor to the top of the Gateway.
3. Use the LMR-400 coaxial cable to connect the antenna to the lightning arrestor.
4. Seal each connection between the Gateway, lightning arrestor, cable, and antenna with
the weather proof tape.

Installation of the WL3/WL4 Option:
1. Mount the antenna on a 2-in. (0.05 m) pipe mast using the supplied equipment.
2. Mount the lightning arrestor using the supplied equipment, minimizing the distance
between it and the building egress for optimal lightning protection.
3. Use the LMR-400 coaxial cables to connect the Gateway, lightning arrestor, and
antenna.
4. Seal each connection between the Gateway, lightning arrestor, cables, and antenna with
the weather proof tape.
Any spare lengths of coaxial cable should be placed in 12-in. (0.3 m) coils.
Ensure that the mounting mast and lightning arrestor are grounded in accordance with
local/national electrical codes.

BEST PRACTICE
Typically, twisted shielded pair cable is used to wire the Serial connection. Standard
practice is to ground the shield on the Serial Host side and leave the shield floating
on the 1420 side. Be sure to insulate the 1420 shield to avoid grounding issues.
NOTE:
In most systems, A = Tx + and B = Rx -. In some systems, this is reversed. For 4-wire
systems, see Figure 2.

Supply Power
After mounting is complete supply power to the 1420 according to the following steps:
1. Ground the 1420 using suitable grounding methods. There is a case ground lug located
near the terminal block, and an external ground lug located near the conduit entries on
the bottom of the housing.
2. Connect the 24 V DC power wiring to the Power Input terminals in the 1420. The 1420
requires 500 mA of current.
3. Close the terminal cover and tighten securely.
BEST PRACTICE
Use an uninterruptible power supply (UPS) to ensure that the network is still
functional should there be a loss of power.
