3.1 Overview
This section describes how to properly mount the Gateway and make electrical connections,
including electrical wiring, grounding, and host system connections. This section also describes
how to mount the optional remote antenna.
3.1.1 General considerations
The Smart Wireless Gateway may be mounted in any general purpose location. Be sure the
covers are secured tightly to prevent exposure of any electronics to moisture and
contamination.
The Gateway should be mounted in a location that allows convenient access to the host system
network (process control network) as well as the wireless field device network.
3.1.2 Physical description
For dimensional drawing information refer to Appendix B: Product Certifications. The cast
aluminum housing encloses the electronics circuitry of the Gateway. The front of the enclosure
has an upper cover and a junction box cover. The upper cover provides access to the electronics
and radio. The junction box cover provides access to the terminal block.
To open either cover, use a ¼-in. bladed screwdriver to remove the appropriate screw on the
unhinged side of the enclosure.
