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:
3.3.1
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 (0,3 m) 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.
Note
Any spare lengths of coaxial cable should be placed in 12-in. (0,3 m) coils.
