Water Module Installation Instructions
General
This leaflet contains instructions for Elster's water meter module (see Figure 1) for use on
water meters to provide readings to the EnergyAxis System. For proper installation and
maximum life of the modules, use the following procedures. All modules are programmed
and sealed at the factory before shipment.
Familiarize yourself with the location and identification of the terminals on the water meter
register before any installation procedure.

Installation
Direct (Integral) Mounting
The water module is shipped pre-wired and attached to a new water meter. Install the water
meter with the EnergyAxis water module as you would any other water meter.
Pit Applications
The water module is shipped pre-wired to the new water meter. However, it is necessary to
mount the water module to the pit cover. The water module is designed to fit standard
(1-7/8 inch diameter) holes in pit covers.
1. Unscrew the cap from the water module. The dome-like cap is fitted to a threaded
cylinder on the top of the module.
2. Adjust the spacer nut as necessary to account for the thickness of the pit cover,
leaving the threaded cylinder protruding above the cover to screw the cap on.
3. Insert the water module's threaded cylinder through the pit cover hole from the
inside of the cover.

4. Screw the cap onto threaded cylinder. This will secure the water module to the pit
cover.
5. Insert the vandal clip into the cap. It may be necessary to twist the water module
cap slightly to make sure the vandal clip is flush with the cap.
Composite pit covers do not require a hole in the cover. These covers have a shelf on the
inside of the cover for water AMR modules. If you are using composite pit covers, slide the
EnergyAxis water module through the slot on the shelf.
Remote Connections
The water module is shipped along with an enclosure housing. The enclosure housing must
be installed, and then the water module cable must be connected to the water meter
register.
The EnergyAxis water module register connections are as follows:
1. There is a label temporarily placed on the water module. Before placing the water
module inside the enclosure housing, remove this label and place it on a visible area
of the enclosure housing.
2. Place the module inside of the enclosure housing (Elster style number 1C11748H01)
provided with the module. Keep the threaded cylindrical portion of the water
module pointing up and slide the module into the enclosure. The enclosure housing
should be held with the arrow on the top of the housing pointing up while the
module is inserted.
3. With the module secured within the enclosure housing, mount the assembly using
the mounting bosses that are on the sides of the housing. Screws are not included
and should be provided by the utility. It is preferable to mount the housing outside
and above ground; otherwise, mount the housing as high as possible.
4. Connect the black wire to the terminal on the water meter register identified as
DATA. Typically, this connection is done by placing the wire under the screw
terminal and tightening down securely. See the product information for your water
meter register for more information.
5. Connect the red wire to the terminal on the water meter register identified as
POWER. Typically, this connection is done by placing the wire under the screw
terminal and tightening down securely. See the product information for your water
meter register for more information.
6. Connect the bare wire to the terminal on the water meter register identified as
COMMON. Typically, this connection is done by placing the wire under the screw
terminal and tightening down securely. See the product information for your water
meter register for more information.
7. If the standard 6-foot cable is not sufficient, splice the cable using a weatherproof
gel cap (for example, 3M style number 314 IDC) to provide greater length. The total
cable length should not exceed 100 feet.
