When installing remote mount antennas for the wireless field device, always use established
safety procedures to avoid falling or contact with high-power electrical lines.
Install remote antenna components for the wireless field device 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 wireless field device 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.
Be aware of overhead electrical power lines.
