Product description
The SGM1430-B meter from Aclara is one of an advanced,
modular designed family of products for small to medium
enterprise and commercial installations.The SGM1430-B
is available in different polyphase variations,and it forms
an integral part of a complete two-way,secure,end-to-end
solution.
The SGM1430-B offers flexibility and the choice of
home area network (HAN) and wide area network
(WAN) communications.As standard,the SGM1430-B
supports different advanced metering infrastructure
(AMI) technologies,including the UK communications
service provider (CSP) hub solution.This hub mechanically
connects directly to the electricity meter and
communicates with it using the ZigBee communication
protocol.A manufacturing option that provides direct
communications via a hardwired interface is also available.
The on-board ZigBee radio frequency (RF) interface
uses an industry-standard Smart Energy Profile for HAN
communications to the UK communications hub and in-
home displays (IHDs) .
The standard meter is supplied with an integrated 3 x 100
A switch for consumer supply connection/disconnection.
Certain models of the SGM1430-B meter offer an optional
2 A load control relay for controlling other ancillary devices
such as night storage heating and pumps.
The meters also support a comprehensive tariff developed
in association with the UK Great Britain Companion
Specifications Standard,plus both seasonal time of day
(STOD) and block tariffs.
Additionally,the meters offer storage for two years of load
profile data and support independent profiling of voltage
profile data (e.g.line voltage, current,frequency). The
SGM1430-B meter also provides,as standard,enhanced
power quality features offering support for sag/swell and
under/over voltage.
Designed with easy installation in mind,the SGM1430-B
meter offers a means for quick and secure deployment,
and a custom-designed Liquid Crystal Display (LCD)
provides added value information.For example, when
ZigBee is used,information such as HAN pairing progress,
notification of pairing complete,local signal strengths for
HAN is displayed to improve the installation experience.
All SGM1430-B meters have a common layout for
buttons,optical port,display, and pulse indicators.The
communications hub interface is also standardised across
all meter models.It’s possible to customise the SGM1430-B
meter with optional variants and extras, including the
following:
• Back-lit LCD
• Hardwired communications interface
• Magnetic detection
• Removal of the HAN

Physical components
Enclosure and covers
The SGM1430-B meters use a thermally stable,UV-
protected polycarbonate enclosure that is double
insulated to protective Class II.The enclosure provides an
Ingress Protection Rating of IP54 in accordance with IEC
60529.The following cover segments are constructed of
polycarbonate 10% GF (Grade Lexan 503RS):
• Meter cover - When the meter is fully installed,the main
cover cannot be removed while the terminal cover is
fitted to the meter.
• Terminal cover – This protects the terminal screws
from external contact.Inside the terminal cover is a
diagram identifying the connections on the terminal
block.This includes a schematic diagram and description
of all physical elements on the terminal block,the
arrangement of active and neutral terminals for the
conductors,and an identifying number defining the
specific variant of terminal.
Cover seals
The meter cover and terminal cover are secured by
standard single sealing screws.Each screw head, which has
a torque value of 0.6-0.9 Nm,features a recessed hole and
slot to accommodate a 0.914 mm diameter thread wire
seal.The sealing wire is crimped close to the body of the
meter using a tool with die indents.As a manufacturing
option,the meter can be supplied with an ultrasonic
permanent seal.
Display
The SGM1430-B meter face has a backlit LCD that
consists of graphical elements and segments.The
graphical section displays the meter status in quantities
up to eight digits,including the unit of measure. It can
also display end user instructions to advise installation
teams that commissioning is complete.The LCD backlight
will illuminate the display when a button is pressed.The
automatic scroll duration,manual scroll timeout,backlight
duration,and contrast adjustment are configurable via the
display settings.
The display shows the following:
• Units of measure
• Constant display of the meter status
• State of the primary supply contactor
• State of the auxiliary control relay (applicable to
SGM1432-B and SGM1433-B)
• Voltage state per phase
• Direction of current per phase
• Signal strength as reported by the HAN module
• Communication status of the HAN network
• Direction of energy (e.g.flowing from the premises to
the network)
• Battery status
• Various data values,meter status, and indications
• Current and historical energy and demand registers
