5.19. Commission E-meter
Commissioning the meter is preparing the meter to
be handled by the system: the meter becomes
operational. During installation in the field, the meter
is updated with the physical installation data like
customer ID, postal code or similar. During
installation, the current configuration as well as other
relevant parameters shall be saved.
During installation, the meter is commissioned via the
optical port by a hand-held device by an installer. The
installer enters and reads a list of relevant information
in the meter by means of an installer security key:
• Time synchronization
• Security key
• Tariff structure ID
• ZIP code
• Meter ID
• Reset alarms
• Disable installation keys
After commissioning, the meter disables the
installation key and blocks the optical port for
communication except for specific readings due to
data recovery, testing and calibration.

5.20. Security
A security model includes authentication and
encryption of data on different levels. Authentication
and encryption keys are delivered from concentrators
to meters. Meters are installed and commissioned to
get the default keys which are changed remotely to
operational keys.

6. Data protection
Special attention is paid to a system of meter data
protection in order to prevent meter tampering.
Access to the billing data registers in order to change
their values is not possible. Entering the RTC
correction constant, meter configuration and auxiliary
terminals can be performed only after entering an
eight digit password and pressing the Param push-
button that is under the meter cover.
7. Meter connection procedure
1. The meter should be fixed with screws at the place
of measurement.
