Chapter 4: Wall Installation This page intentionally left blank. 22 L900 MIU Pit and Wall Installation and Maintenance Guide Chapter 5: Pit Installation This chapter describes storage and unpacking instructions, preliminary tests, tools, materials, site selection, and pit installation of the L900 MIU. Prior to Installation Storage Upon receipt, inspect shipping containers and contents for damage prior to storage. After the inspection is complete, store the cartons in a clean, dry environment. Keep in mind that the L900 MIU has an internal battery. Storage for more than one year can affect product life. Be sure to use a first-in first-out inventory control system. See "Environmental Conditions" on page 4 Unpacking As with all precision electronic instruments, the L900 MIU must be handled carefully; however, no additional special handling is required. After unpacking the L900 MIU, inspect it for damage. If the L900 MIU appears to be damaged or proves to be defective upon installation, notify your Neptune sales representative. If one or more items requires reshipment, use the original cardboard box and packing material. Figure 23 – L900 MIU Kit L900 MIU Pit and Wall Installation and Maintenance Guide 23 Chapter 5: Pit Installation Tools and Materials Table 8 on page 9 and Table 9 on page 10 show the recommended tools and materials you need to successfully install the L900 MIU. Some items may not apply to your specific installation, or the list may not contain all required tools or materials. Site Selection Always follow your company's safety practices and installation guidelines when installing an L900 MIU. Never perform an installation during a lightening storm or under excessively wet conditions. Installation and operation in moderate temperatures increase reliability and product life. See "L900 MIU Pit Environmental Conditions" on page 4. Follow these guidelines when selecting a location to install the L900 MIU. For best results, select a location where there is no chance that another object can be set over the antenna. Avoid installing the L900 MIU behind metal fences or walls. Make sure the pit location gives adequate room for installing both the L900 MIU and the pit antenna. For maximum performance, the flange of the pit antenna needs to be located above the pit lid. For maximum performance, Neptune recommends that pit antennas be installed above the lid as illustrated in Figure 24. Figure 24 – Antenna Placement for Low Traffic Areas 24 L900 MIU Pit and Wall Installation and Maintenance Guide Chapter 5: Pit Installation When installing in a high traffic area, Neptune recommends that the dome of the antenna be recessed in the pit lid as shown in Figure 25. Recessing the installation reduces the range of the antenna. Figure 25 – Antenna Placement for High Traffic Areas For best results, Neptune recommends installing the L900 MIU in a location that provides a direct line of site to the path of the meter reader. Although the L900 MIU has a cable already attached (2 feet or 6 feet), some installations can require additional cable. In these cases, the maximum cable length between the encoder register and L900 MIU depends on the register's manufacturer and model. Refer to Table 11 for maximum cable lengths. Table 11 – Cable Length and Manufacturer Encoder Register Maximum Cable Length Neptune ARB V* 300 feet (91 meters) Neptune ProRead / E-CODER 500 feet (152 meters) Sensus Protocol Register 200 feet (61 meters) * Meets manufacturer's published specification for wire length between encoder and remote receptacle.

L900 MIU Pit and Wall Installation and Maintenance Guide 33 Chapter 5: Pit Installation This page intentionally left blank. 34 L900 MIU Pit and Wall Installation and Maintenance Guide Chapter 6: Data Logging Extraction About Data Logging The L900 MIU is capable of storing interval data for data logging. The L900 MIU is activated using the Trimble® Nomad® and R900® Belt Clip Transceiver (R900 BCT) and is explained in more detail in the following section. The L900 MIU stores consumption in hourly intervals for a rolling total of 96 days. This is equal to 2,304 hourly intervals of consumption. The data logging data is extracted through RF activation. The RF activation allows the utility workers to visit the location and extract the data without physically interacting with the meter itself. This limits the worker’s exposure to animals or other dangerous situations. The extraction process, once started, takes approximately 30 seconds. The activation is done through the HHU connected to the R900 BCT via Bluetooth. The activation signal is sent by the R900 BCT to the L900 MIU which in turn sends the data intervals to the R900 BCT and are saved in the HHU. Accessing Data Logging Complete the following steps for data logging. 1. From the host software home screen on the HHU, click MENU. See Figure 46.
