Liberty 100 Smart Electricity Meter Technical Reference Manual
Local communication port
Local communication is provided by an IEC 1107 port supporting a maximum data rate of up to 9600 baud
which is the default.
Metrology LED
The red LED adjacent to the meters keypad flashes at a rate proportional to the instantaneous active power.
Over time, the flashes correspond to the amount of energy registered by the meter. The metrology LED emits
3200 flashes for each kWh measured.
Power and hub communication LEDs
The LED on the left indicates power, the middle LED indicates WAN network activity and the LED on the right
HAN network activity. See Section 6 ‘Communication Hub (Skyline-i 510)’ for details. The flashing frequency
indicates the current activity of the hub.
Hub pair button
The hub has a push button which is used for HAN pairing with in-home devices (only used when operating in
external mode i.e. not integrated with a Liberty 100 meter).
3.1.1 Front Cover
The meters front cover is manufactured from polycarbonate with a transparent window to view the display and a
flange to protect the meter from dust and moisture ingression. Two sealable screws, one at the top beneath the
communication module the other at the bottom beneath the sealable terminal cover secure the cover to the
meter base. The enclosure is designed to IP52. Provision is provided for front cover open detection in power on
and off conditions.
