EA_Water 2.0 module

Installation instructions

General

This leaflet contains instructions for Elster’s EA_Water 2.0 module 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.

The EA_Water 2.0 module can be installed as an integral, wall, or pipe mount. The integral mount consists of the module
being mounted directly to the water meter. See “Integral mount” on page 1 for specific instructions. The wall mount is
mounted to a mostly flat surface such as a wall or other surface. See “Wall mount” on page 2 for specific instructions. The
pipe mount consists of hardware to mount the module to a pipe. See “Pipe mount” on page 4 for specific instructions.

Familiarize yourself with the location and identification of the terminals on your water meter registers before any installation
procedure.

Radio communications performance and mounting

The EA_Water 2.0 module is designed to provide excellent radio communications performance when it is mounted such
that the front surface arrows point up. Alternate mounting orientations may impair radio communications performance.

Integral mount cover

1. Align the hoop EA_Water 2.0 module over the water meter register so that the EA_Water 2.0 module wires are
able to connect to the water meter terminals.

2. Securely attach the EA_Water 2.0 module over the water meter register.

3. Using the table in “Connection instructions” on page 1, connect the appropriate wires to the correct terminals on
the water meter register. Typically, the connection is made by placing the wire under the screw terminal and
tightening down securely. See the product documentation for your water meter register for more information.

Wall mount

The EA_Water 2.0 module can be mounted on a wall close to the water meter. To assist placing the enclosure on the
hanging screw, the enclosure has hash marks that will help you properly align the module.

The cable from the EA_Water 2.0 module and the water meter register should not exceed 100 feet (30 meters).

1. Remove the remote mount cover from the EA_Water 2.0 module.

Be sure to connect the cables correctly. Failing to properly connect the cables may prevent the module from operating
correctly. For information on proper connections, see “Connection instructions” on page 1.

2. For proper operation of the module, connect the cables as described in “Connection instructions” on page 1.
a. If you do not have an inline connector, splice the cables from the EA_Water 2.0 module to the water meter

register cable using weatherproof gel caps (for example, 3M style 314 IDC). Be sure to follow the
manufacturer’s directions for wire preparation when using gel caps.

CAUTION

!

Cable tie

Be sure to carefully

align arrows

Insert the cable back into the EA_Water 2.0 module, making sure to provide strain relief for the cable. Be sure
to securely fashion the cable by using the cable tie, as illustrated in the next figure.

Be sure that the arrows are as closely aligned as possible before mating. Failing to properly align the arrows may result in
damage to the connector, requiring a replacement of either the connector or the module itself.

b. If you have an inline connector, align the arrows on both connector ends. Press firmly to fully mate the

connectors (see next figure).

3. Reattach the remote mount cover to the EA_Water 2.0 module.

4. Hang the EA_Water 2.0 module on the hanger screw, making sure it is level.

5. Screw 2 screws into the 2 bottom supporting screw mounts.
