GPS Antenna

The Connected Grid GPS Antenna kit (optional) includes the following items:
GPS antenna with integrated 15-foot coaxial cable (see
Male QMA connector adapter, to connect the cable to the router GPS antenna port
Hardware required to mount the antenna, for example on the substation or utility cabinet exterior
This antenna provides connectivity to the GPS system, from which the router derives precise time and location
information while operating on the network.
GPS Antenna Information
Caution:
If the antenna is mounted outside, the antenna assembly must be grounded either at the bracket or at the
external building point where the cabling enters the building. This is critical because if it's not grounded, the CGR 1120
chassis would be isolated on the antenna card very close to AC isolation requirements. Also see Statement 1052 below.
Warning:
Do not locate the outdoor antenna near overhead power lines or other electric light or power circuits, or
where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into
contact with such circuits, as they may cause serious injury or death. For proper installation and grounding of the
antenna, please refer to national and local codes (for example, U.S.:NFPA 70, National Electrical Code, Article 810,
Canada:Canadian Electrical Code, Section 54). Statement 1052
The GPS antenna is a field-replaceable component.
