I NTRODUCTION
The purpose of this document is to provide qualified metering personnel with
product description; operating, maintenance, and upgrading instructions; site
analysis guides; and diagrams for the SGM1400-B Series smart meter family. It is
not intended to replace the extensive training necessary to install or remove meters
from service. Any work on or near energized meters, meter sockets, or other
metering equipment presents the danger of electrical shock. All work on these
products must be performed by qualified industrial electricians and metering
specialists only. All work must be done in accordance with local utility safety
practices and procedures.

P RODUCT D ESCRIPTION
The SGM1400-B meter from Aclara is an advanced modular designed family of
products for domestic and small commercial installations. The SGM1400-B is
available in both single phase and dual element variants, and it forms an integral
part of a complete two-way, secure, end-to-end solution.
The SGM1400-B has been designed to offer flexibility and the choice of home
area network (HAN) and wide area network (WAN) communications. As
standard, the SGM1400-B supports different AMI technologies, including the UK
CSP communications hub solution. The communications hub mechanically
connects directly to the electricity meter. The hub communicates with the meter
using the ZigBee communication protocol. A manufacturing option that provides
direct communications via a hardwired interface is also available.
The on-board ZigBee RF interface uses industry standard Smart Energy Profile
for HAN communications to the UK communications hub and in-home display
(IHD) respectively.
The standard meter is supplied with an integrated 100A switch for
connect/disconnect of the consumer supply. Certain models of the SGM1400-B
Series meter offer an optional 2 A load control relay, whilst others support an
additional 100 A contactor for control of other ancillary devices such as night
storage heating, pumps, etc.

General Information
The meters also support a comprehensive tariff developed in association with the
UK Great Britain Companion Specifications Standard and supports 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 instrumentation values, typically line voltage,
current, frequency, etc. The SGM1400-B Series meter also provides, as standard,
enhanced power quality features offering support of sag/swell, under/over voltage,
and max and min.
Designed with installation in mind, the SGM1400-B Series meter offers a means
for a quick and secure deployment. A custom-designed 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, etc. is
displayed to improve the installation experience. Refer to Installation on page 71
for more information on installing an SGM1400-B Series meter.
All SGM1400-B Series meters have a common layout for buttons, optical port,
display, and pulse indicators. The communications hub interface is also
standardized across all meter models. The SGM1400-B Series meter can be
customized with optional variants and extras, including the following:
• Back-lit LCD
• Hardwired Communications Interface
• Magnetic Detection
• Removal of the HAN

P HYSICAL C OMPONENTS
The SGM1400-B Series smart meter family comprises of a single phase and single
phase with 2 A relay output. The main physical features of a SGM1400-B Series
meter are shown below.
Enclosure and Covers
The SGM1400-B Series 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 - 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
Cover Seals
The meter cover and terminal cover are secured by standard single sealing screws.
The torque value for the sealing screw is 0.6-0.9 Nm. The screw head has 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 also be supplied with an ultrasonic
permanent seal.
Display
The SGM1400-B Series meter provides a backlit Liquid Crystal Display (LCD)
located on the meter face. The display 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 object.
The display shows the following:
• Units of measure
• Constant display of the meter status
• State of the primary supply contactor
• State of the secondary contactor (applicable to SGM1415-B, SGM1416-B,
and SGM1422-B)
