6 Meter Installation
Safety Warnings
Before you install and operate your meters, you should be familiar with all regulatory
agency, manufacturer, and utility industry safety precautions. Observe these safety
precautions during all steps of meter installation, operation, and service. Failure to
comply with these precautions, or with specific warnings or instructions elsewhere in this
guide, violates safety standards of design, manufacture, and the intended use of the
meter. Echelon assumes no liability for failure to comply with these requirements.
The information presented in this guide is intended to be an aid to qualified metering
personnel. It does not replace the extensive training necessary to handle metering
equipment in a safe manner.
Safety Warning: Any work on or near energized meters or other metering
equipment presents the danger of electrical shock. Only qualified electricians
and metering specialists should be authorized to work with the meters, in
accordance with local utility safety practices, utility requirements, and other
safety precautions as dictated by local code, regulations, or statutes.
Visual Meter Inspection
Before installing the meter, inspect the meter case, display, optical port, and blades to
make sure they are not damaged.
Safety Warning: Return damaged meters and components to Echelon; do
not attempt to repair the damage. The meter has no user-serviceable parts.
Any attempt to remove or repair internal parts voids the meter warranty.
Provisioning the Meter
Before a meter can operate correctly in your system, it must be configured with specific
operating parameters. This configuration is called “provisioning” and is performed by
writing programs with preset values into the meter, either from NES System Software
via the Data Concentrator, or directly to the meter optical port from a computer using
the NES Provisioning Tool application. The parameters in the Provisioning Tool
programs are set by administrative staff at the governing utility, and the programs can
be distributed to technicians for meter provisioning operations.
The meter provisioning may be performed by Echelon prior to shipment, at a service
depot before transportation to the meter installation site, or at the installation site.
After a meter is installed, updates to program settings are usually performed by sending
the updated information from NES System Software to the Data Concentrator that is
supervising the meter. The Data Concentrator writes the update to the meter and
confirms the successful implementation back to NES System Software. For more
information on the Data Concentrator, see the DC-1000/SL and DC-1000/SLE Data
Concentrator User’s Guide.
You can also use the Provisioning Tool to view meter data and diagnostic information.
For instructions on provisioning meters, see the NES Provisioning Tool User’s Guide.
