Introduction
Cashpower Gemini HMI is part of the Gemini family of prepayment meters and is a single-phase,
keypad-based, stand-alone or split prepayment electricity meter in a British Standard housing. If used
as a split prepayment meter, it comprises two parts, namely the meter and the customer interface unit.
The Gemini MMI can be used as a stand-alone prepayment meter, typically
installed inside the household, or can be used as a split prepayment meter by
simply connecting the customer interface unit, which will then be the customer‟s
only interface with the meter.
When used as a split metering solution, the meter is usually installed in a secure, locked enclosure,
typically a pavement kiosk or pole-mounted equivalent. The customer interface unit is usually installed
in a convenient location in the consumer‟s home - remote from the meter and is connected to the
meter with a pair of communications wires.
