BEC62(08) product overview
The BEC62(08) is a three-phase, four wire, STS compliant prepayment electricity meter ideal for
residential, commercial and light industrial electricity metering applications.
The device is also termed a “split” meter, consisting of two items; the MCU (measurement control unit
and the UIU (User interface unit). The MCU is installed outside the customer premises in a meter box
or kiosk, while the UIU sits inside the customer premises.
The BEC62(08) solution provides a number of innovations, the split function serves as a great
advantage to the utility as access to the meter is restricted, thereby reducing the chance of meter
tamper. The unit also has a wide range of programmable functions, to provide a high level of
customisation for each utility.

This LED has a dual function - it indicates the rate of consumption and is also used to verify the
accuracy of the meter.
The LED flashes faster to indicate a rapid consumption of electricity.
The LED pulses 1,000 times for every kWh of energy measured.
Virtual token carrier (VTC)
The BEC62(08) meter supports two VTC interfaces.
Direct probe port (type A)
This port is primarily used to extract data from an uninstalled meter using a hand-held unit, as
it enables the interrogator unit to supply power to the meter.
The physical port is shared with the flags port; therefore only one channel can be used at a
time.
The flags port takes priority.
Flags probe port
This port is primarily used to extract data from an installed meter using a hand-held unit.
The physical port is shared with the direct probe interface; therefore only one channel can be
used at a time.
The flags port takes priority.
This port is optically isolated, so you are protected and totally isolated from the mains supply.
This port only operates when the meter is powered.
You cannot power the meter through this interface.

Installing a wireless solution
The BEC62(08) can be converted into a wireless meter, through the addition of a Wireless Meter
Interface (WMI) which enables RF communication from the meter to the Wireless User Interface Unit
(wUIU). It is important to note that the wireless solution requires a wUIU to be installed in the
consumer’s home.
To install the wireless meter interface (WMI):
The WMI is installed close to the meter to enable RF communication. The WMI can be installed on a
pole with cable ties, or within a pole top box on a DIN rail. When installed in an unobstructed
environment a distance of up to 150 metres, line of sight, can be achieved between the two devices.
Once positioned, the communication cables from the WMI are connected onto the meter terminals 12
and 13, by pushing back the orange clips. The terminals are not polarity sensitive (See Figure 2,
Wiring instructions).
