Quick Start Guide
Remote antenna (optional)
The remote antenna options provide flexibility for mounting the Gateway based
on wireless connectivity, lightning protection, and current work practices.
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- to 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:
Installation of WL2/WN2 option (outdoor applications)
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.
When installing remote mount antennas for the Smart Wireless Gateway, always use
established safety procedures to avoid falling or contact with 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 installing, consult with a local area electrical inspector, electrical officer, and
work area supervisor.
The Smart Wireless 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 Process Management is not responsible for wireless performance or
non-compliance with spectrum regulations.
