Installing the 100W and 100WP ERT Module
TDC-0909-004 100W and 100WP Datalogging ERT Module Installation Guide 13
Proprietary and Confidential
100W and 100WP ERT Modules with Integral Connectors
If 100W and 100WP ERT modules with integral connectors (ERW-1300-X0X) and the registers are not
installed at the same time, secure the protective connector cover on the ERT module using an Itron Security
Seal (Itron part number MSC-0018-001). Cable ties are not shipped with the 100W and 100WP ERT module,
but can be ordered from Itron. Use the protective cover (on the ERT module side) in the field for up to one
year.
Warning If a three-port 100W and 100WP ERT module is installed but the Leak Sensor is not
attached, the environmental cap (MSC-0019-008) must remain in place on the blue connector
(Leak Sensor connector) to protect the connector from damage.
To install a security seal (MSC-0018-001) through the protective connector cover
1. Align the protective cover and connector security seal holes.
2. Insert the security seal pointed end through the security holes in the connector and protective cover.
3. Insert the pointed end of the security seal into the cap end and push until the seal locks.
Rod Mount Installation
100W and 100WP ERT modules can mount below the pit lid on a customer-supplied 1/2-inch OD rod. The
example installation described in this section uses a fiberglass rod. For more information, visit www.itron.com
and reference the Water Meter Compatibility List (PUB-0063-002).
Warning The rod installation area must be free from other pipes, wires, or facilities that may
be damaged by driving a rod into the ground.
Caution You must follow local codes when using the rod mount installation method. Failure to use
1/2-inch rod and follow instructions may result in an unreliable installation.
Observe the following guidelines for mounting the 100W and 100WP ERT module using the wall mount
procedure:
ERT module positioning other than upright could negatively affect radio performance
and battery life.
Use only Itron-approved splice kits or inline connectors.
