Page 7 of 30 2Getting Started: Routing Node-ERT Gateway Mesh The Routing Node-ERT Gateway Mesh provides a unified means of reading Itron R300/R400 electric meters over an IPv6 network. The ERT Gateway Mesh communicates directly with the Connected Grid Router (CGR). The gateway utilizes RF links with optimized modulation rates. The CGR then transmits the data to the OpenWay Operations Center (a part of the head-end system) over the utility's backhaul communication solution. The ERT Gateway's flexible design provides installation options for a variety of wall-mounted or pole-mounted locations. This flexibility provides optimal communication effectiveness and range and minimizes installation costs. Important! Installation must be completed by professional installers to ensure trouble-free operation of the Itron OpenWay system. Follow these product installation instructions to ensure proper operation of your Routing Node ERT Gateway Mesh. Important! Use the ERT Gateway shipping packaging to transport the ERT Gateway. The shipping materials protect the ERT Gateway from damage. 15 June 2020 815-0322-00 Rev0 Itron, Inc.

Page 12 of 30 Routing Node ERT Gateway Mesh Installation Guide 2 Getting Started: Routing Node-ERT Gateway Mesh ERT Gateway Antennas The ERT Gateway utilizes three antennas. ERT antenna: The ERT antenna is a custom designed, 5.5dBi antenna that mounts directly to the top of the ERT Gateway Mesh housing. WAN antenna: The WAN antenna is a custom designed 2.6dBi antenna that mounts directly to the bottom of the ERT Gateway Mesh housing to support the customer's backhaul data requirements. Caution: This equipment has been designed and approved per FCC and ISED rules to operate with these antennas. To reduce potential radio interference to other users, the antenna type and its gain were chosen so that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication. Antennas not included in this list and approved by Itron are strictly prohibited for use with this device. Installing the Routing Node ERT Gateway with an unapproved antenna will void the product warranty and can void the user's authority to operate this equipment. Internal Wi-Fi antenna:The Wi-Fi antenna is used for local access to the device. The effective range is approximately 100 feet from the front (1) of the ERT Gateway Mesh and approximately 50 feet to the rear (2) of the device. The shown coverage area assumes the device is mounted at a height of 25 feet with a clear line-of-sight path between the ERT Gateway Mesh and the programming device. 15 June 2020 815-0322-00 Rev0 Itron, Inc. Page 13 of 30 3Planning an ERT Gateway Installation This chapter describes ERT Gateway installation preparation and planning. Installation Profiles The ERT Gateway may be installed in a variety of configurations and locations (for more information, see Installation location information on page 3). Itron identified the following profiles for ERT Gateway installations. Location Location description Utility pole The ERT Gateway is installed on a utility pole. Light pole/street light The ERT Gateway is installed on either a light pole or the davit arm of the street light. Pipe or mast The ERT Gateway is secured/installed to a pipe or fence railing (from 2 to 3.5 inches in diameter). Siting the ERT Gateway ERT Gateways can be installed in the field on a variety of surfaces. Examples of siting surfaces include:
wooden or metal walls metal pipes fence railings utility poles In determining the ERT Gateway placement, observe the following primary considerations. Best practices are to site the ERT Gateway:
For optimum RF reception. In a location where there is a power connection. On a structure or in a location that can physically support the weight of the ERT Gateway
(and its mounting hardware). Caution: Always get permission to install the ERT Gateway at the selected site prior to installation. If you have questions or need help, contact Itron Support. 15 June 2020 815-0322-00 Rev0 Itron, Inc.

In accordance with FCC rules, unapproved modifications or operation beyond or in conflict with these use instructions could void the user's authority to operate the equipment. Only authorized Itron personnel may open the ERT Gateway. Unauthorized access or modifications to the ERT Gateway will void the warranty. Propagation Study for the ERT Gateway Installation Site Prior to the ERT Gateway field installation, contact Itron. Itron performs a propagation study to:
evaluate the quantity and types of network endpoints. assess the environmental and geographical considerations for the ERT Gateway installation. optimize the ERT Gateway placement within the network to get the best possible reception. assess the physical and structural implications of the selected mounting surface. The propagation study provides the information to determine the exact ERT Gateway installation location and the best mounting surface. This iterative process may be repeated as the final installation parameters are determined. 15 June 2020 815-0322-00 Rev0 Itron, Inc. Page 15 of 30 Routing Node ERT Gateway Mesh Installation Guide 3 Planning an ERT Gateway Installation AC Power Requirements The ERT Gateway Mesh requires an 85-264 VAC source defined as a 10 Amp or 15 Amp branch circuit that must be protected by a certified branch circuit breaker. Warning! Do not connect the ERT Gateway to a circuit protected by a GFCI breaker. The wiring must be sized in accordance with the National Electrical Code, ANSI/NFPA 70 and, where applicable, the Canadian Electrical Code, Part I, CSA C22.1 or the prevailing local code. Mounting Hardware Requirements Mounting hardware requirements are based on the installation location and your system configuration. The installer must supply the following mounting hardware to properly attach the ERT Gateway to the mounting surface. Caution: Each installation is unique. You must ensure the mounting hardware securely supports the ERT Gateway. The ERT Gateway without the mounting hardware weighs 8 pounds. Itron recommends you consult a qualified engineer to verify load requirements and safety issues. Installers must comply with local codes when the ERT Gateway is installed.
