5.15.1 'READY' state

For safety reasons a 'READY' state is supported between the supply off and on states. This gives the User the
control to reconnect their supply from the meter or IHD when it is safe to do so (e.g. appliances are off). When
the meter's switch is in 'READY' state, the 'READY' icon will illuminate on the LCD and an appropriate message
will be displayed which signifies that the meter is ready to reconnect supply and is waiting for the user to press
the correct key sequence on the meter's keypad or IHD.

5.15.2 Closing the switch from the 'READY' state

When the switch is in the 'READY' state, the 'READY' icon will illuminate on the meter's LCD followed by the
messages 'PRESS A' and 'CONNECT'. Pressing key 'A' on the meter displays 'Press B' followed by
'CONFIRM'. Pressing key 'B' within 30 seconds of pressing key 'A' closes the switch and reconnects the supply
otherwise it will stay in the 'READY' state and the meter's display reverts back to 'PRESS A' followed by
'CONNECT' display sequence.
