3 Precautions and Safety Practices
1. Energy meters are generally installed in electrically live surroundings. To minimise the risk of electrical
shock, stay away from loose or exposed electrical connections. If there is loose or exposed electrical wiring
near the installation site, initiate appropriate preventive measures.
2. Check for the wiring configuration of the meter and ensure that the meter is installed for the appropriate
wiring connection.
3. Before energizing the meter, ensure that no stray strands of wire are present outside the connector blocks.
4. Meter must be protected by fuses or voltage isolating links in each voltage circuit.
5. Under no circumstances should the current transformer (CT) connections to the meter be disconnected
while current is flowing in the primary circuit of the external CT.
6. Ensure that the connected load does not exceed the current range specified on the rating plate.
7. The meter contains a battery that must be disposed of in a suitable manner at the end of its life.
8. Secure Meters recommends carrying out regular installation checks, especially when the product is installed
at locations posing higher risk of degradation or corrosion – such as under direct, strong sunlight, areas with
high ambient temperature and little ventilation, areas near heat sources like a furnace, areas near sea or a
water body, areas where the meter is regularly exposed to chemical fumes, etc.
9. It is recommended to immediately cut off the meter supply upon occurrence of any fault within the meter.
10. Keep the meter away from fire, corrosive chemicals, and fumes thereof, rain and direct, prolonged exposure
to water.
11. The electrical installation of electronic meters at a site requires an adequate understanding of all governing
rules and regulations.

8 External Features
Given below is a detailed description of the various parts that make up Premier 300.
Figure 1: Premier 300 part details
Name Plate:Displays the basic electrical and ownership information about the meter such as voltage and
current ratings, number of phases, barcode, serial number, month and year of manufacture, property of
(customer name and logo), part no., etc.
Meter Base and Front Cover:The base or enclosure of the meter is made of a high-grade fire retardant
poly-carbonate. The front cover, made of the same material, is fastened to the base with screws. A sealing
arrangement is provided to prevent tampering.
Push Buttons:Two push buttons, namely left and right buttons, allow interactions with Premier 300. These
buttons are used for various user operations such as display navigation, page mode selection, MD reset,
etc.There is provision of sealing left push button.
LCD Display:A large multi-segment LCD that supports alpha-numeric characters for displaying information
and values for various electrical parameters recorded by the meter.
IEC 1107 optical port:An optically-isolated, sealable port to enable data to be transferred to and from the
meter (for billing or downloading new parameters) through optical probe. This port is immune to spurious
external electrical signals.

PUBLIC BGX501-747-R04, Premier 300 User Manual Page 13 of 41
Terminals and Terminal Block:There are eleven main terminals at the bottom of Premier 300. The
arrangement of terminals is 1S (In), VR, 1L (Out), 2S (In), VY, 2L (Out), 3S (In) VB, 3L (Out), N (In) and
N (Out). In addition to these, there is a smaller termination on the left for fixing RJ11 connector for
communication on RS 232 and in RS485 variant RJ11 is on the right hand side. A terminal block, capable of
sustaining high temperature, is provided in the meter with adequate provisions for connecting wires to the
meter.
Extended Terminal Block Cover:ETBC not only protects the terminal connections from attempted
tampers and external interference but also enhances human safety from electrical hazards.
Sealing screw for ETBC:This screw facilitates the necessary sealing arrangement after the installation of
the meter in the field.
LEDs: Premier 300 has two metrological LEDs: while the left LED indicates the rate of consumption of
active energy, the right LED can be configured to indicate several different energies.

9 Using the Display
Premier 300 is equipped with a large multi-segment alpha-numeric LCD display and two buttons for the
essential user interface. Display parameters for Premier 300 are configurable through BCS.
Figure 2: All segment check for the LCD Display of Premier 300
The LCD screen has various sections and annunciators for displaying specific bits of information such as
current status of the meter, parameter values, user messages etc. An annunciator or a section corresponding to
the demanded information is illuminated at the time of display.
Details of individual sections are summarized below.
S. No. Icon / Segment Details / Remark
1
7 large 7 segment character display with 5 decimal points for alpha-numeric
displays.
2. 3 large 11 segment character display for alpha-numeric displays
3.
OBIS code - 8 small 7 segment character including 1 of 2 segments. This is
a standard code under DLMS understood by diverse communication
entities. OBIS code specifies six value groups for displaying meter data
information viz. A,B,C,D,E,F. Depending on the meter type, information
could be displayed using some or all of these value groups. Premier 300
displays information using value groups C, D, and E only. The significance
of each group is explained below:
Value Group ‘C’: Identifies the physical quantity measured by
the meter. For example Voltage, Line Currents etc.
Value Group ‘D’: Identifies how a parameter is processed for
example whether the parameter is logged instantaneously or
over an integrated time period such as (MD)
Value Group ‘E’: Identifies the different rate registers available in
the meter
4. Unit and multiplier indicator. These icons display unit values using proper
combination of characters like k, V, W, A, h.
5. Billing indicator
6. Critical event indicator

7. Cover open indicator
8. Magnet tamper indicator
9. Phase presence indicator
10.
Quadrant indicator shows import, export, lag and lead. This indicates type of
energy being displayed which can be basic import or export, inductor and
capacitor for reactive lag and reactive lead respectively.

Table 6: Operations possible through Premier 300 buttons
9.1.1 Push-Button Mode
The meter supports a list of parameters which can be displayed on the LCD. This requires configuring a
sequence of parameters called Display Sequence. The buttons provided on the meter can be used to scroll
through this sequence.
Premier 300 supports Page Mode display view. Multiple pages can be selected. While a long push (button
press > 5 seconds) allows page navigation, a short push allows scrolling through the available displays in a
page.
The default first display parameter will be the lamp test display with all display segments on. Upon reaching the
end of a display list, the display rolls over again to show the first one in Auto Mode.
A display on the LCD remains on until the normal on time is elapsed. The normal on time is configurable.
After timing out of the manual mode, the display switches to the sleep mode and reverts to auto mode
thereafter. Sleep period, or the display off time, is configurable.
9.1.2 Auto mode
Auto Mode is the default mode for the Premier 300 display. The configured parameters scroll automatically with
a specified period. The auto display cycle ends with a brief sleep mode. Upon recovering from the sleep mode,
the display cycle repeats for selected displays. Upon power interruption, the display starts in auto mode.
The Left button is used for performing the MD Reset operation. This requires pressing the Left button for five
seconds.
