II. Meter Model
The counters are two models
1. Counters such SPLIT
They consist of two separate modules
a) Measurement Module: It is responsible for measuring electrical parameters (energy, power,
current, voltage, etc.) and protection of the meter (circuit breaker).. This module is expected to be
deported and placed out of reach of the client (support distributor niche)
b) Client Interface Module: It allows the client to communicate with the meter with the introduction
of credit and view information about the counter (credit level, consumption, electrical parameters,
etc.)..
Two options are proposed for the communication between the two modules:
- A wired communication via a telecommunications cable connecting the two parts over a maximum
distance of 150 m,
- A communication by CPL.
2. The Monobloc type counters
Counters Monobloc type are composed of a single module integrating the measurement system and
the client interface.

V. Warranty
The meters are guaranteed for one year from the date of receipt in Dakar. This warranty covers any
abnormalities in the functioning of the meter and involves the replacement of faulty meter with a
new meter at the expense of the bidder.
During the warranty period any malfunction found showing non-compliance with the requirements
specified herein entitles Senelec to claim the replacement of all meters affected lots borne by the
bidder.
The objective, the choice of components and the hardware architecture, is that the counter field
service is a global failure rate less than or equal to 0.5% per year throughout the life desired product,
that is to say, for at least 15 years.

of equipment. To take into account "setup stress", there may be a failure rate of up to 1% during the
first year after commissioning.
In case of failure of more than 1% in a batch, all the meters in the lot in question will be replaced at
the expense of the dealer and the warranty for the replacement meter set at one year after the date
of receipt.
