Issue 1.2
The meter is fitted with an integrated supply control switch to connect or
disconnect the supply to the consumer's premises. The supply control
switch can be operated manually via push button when in an 'armed' state,
remotely by commands, or locally through control functions integrated in
the meter itself.
The supply control switch control is designed so that it enables the utility to
use the supply control switch as:

a switch for disconnecting the premises when the customers move
away or when grid maintenance is required;

a prepayment-mode supply control switch such that consumers may
be disconnected when prepaid credit runs out and reconnected when
prepaid credit is topped-up;

a load-limiting supply control switch where supply can be disconnected
if the consumer exceeds the load limit power threshold (Active power
threshold in kW). Reconnection can be maintained by ensuring that
consumer usage is below the disablement threshold.
No overcurrent protection/automatic disconnection
The supply control switch is not equipped with a thermal and/or short circuit
protection device. Do not use the supply control switch as an isolator.
To properly control the behaviour of the supply control switch under all
operating conditions a control unit is implemented. It is triggered by the
following sources:

Supply control switch push button B on the meter's face plate

Remote commands

Internal commands

External request actions
