. INTRODUCTION
A Prepaid Energy Meter enables power utilities and the maintenance team to collect electricity bills
from the consumers prior to its consumption. The prepaid meter is not only limited to Automated
Meter Reading [AMR] but is also attributed with prepaid recharging ability and information exchange
with the utilities pertaining to customer’s consumption details.
The idea of prepaid metering will be very important for the new research fields of Micro-grid and Smart
Grid and is an inevitable step in making any grid smarter than it is now. Prepaid is a plan that deducts
usage charges and any fixed charges from account balance each day. Consumer is expected to take
responsibility.
This U n i q u e product termed as C o n t a c t l e ss p r e p a i d e n e r g y meter d e v e l o p e d by E l m e a s u r e , is
p r o b a b l y the first o f its kind in t h e I n d i a n meter m a n u f a c t u r i n g history. T he d e s i g n is c o m p l e t e l y
m i c r o c o n t r o ll e r based thus p r o v i d e s e ff e c t i v e s o l u t i o n to t h e e l e c t r i c a l service p r o v i d e r s . T he a c t i o n
r e q u i r e d by the service p r o v i d e r is just to i n s t a ll the meter and f u r t h e r a c t i v i t i e s involve o n l y the
consumer, which then is a very s i m p l e procedure to be f o ll o w e d . I t is s u ff i c i e n t f o r the service p r o v i d e r
to have only one m a n power or no man power to recharge the meter as per the c o n s u m e r ' s
r e q u i r e m e n t . This is not only limited to power and energy, Elmeasure devices also can integrate gas
and water meter with the different inlets of the house and deduct the balance based on consumption.
The meters can be networked with RS485, GSM/GPRS. The unique data communication enables the
secured recharging of the meter. Elmeasure has developed ELNet PPS software which enables the
customer to recharge the meters 24x using the payment gateway without even visiting the service
provider.
The microcontroller acquires signals from the metering element(s), processes them and calculates
values of measured energy or gas and water. The results are stored in registers for particular tariffs.
The microcontroller also generates pulses for the LED and, enables two-way communication via the
RS485 and drives the LCD and the control outputs.
. . IMPORTANT INSTRUCTIONS

2. INSTALLATION
2. . SAFETY WARNINGS
Before you install and operate your meters, it is important to be familiar with all regulatory
agency, manufacturer, and utility industry safety precautions. Observe these safety
precautions during all steps of meter installation, operation, and service. Failure to comply
with these precautions, or with specific warnings or instructions elsewhere in this guide,
violates safety standards of design, manufacture, and the intended use of the meter.
Elmeasure assumes no liability for failure to comply with these requirements.
The information presented in this guide is intended to be an aid to qualified metering
personnel. It does not replace the extensive training necessary to handle metering equipment
in a safe manner.
Safety Warning: Any work on or near energized meters or other metering
equipment presents the danger of electrical shock. Only qualified electricians and
metering specialists should be authorized to work with the meters, in accordance
with local utility safety practices, utility requirements, and other safety precautions
as dictated by local code, regulations, or statutes.

!
INCOMING INSPECTION
Before the meter is installed, visual inspection, for any damage in the process of
transportation, has to be carried out.
Safety Warning: Return damaged meters and components to Elmeasure do not
attempt to repair the damage. The meter has no user-serviceable parts. Any
attempt to remove or repair internal parts voids the meter warranty.
REPACKING
If the meter has to be returned to the supplier, repack the unit in the packing in which it was
supplied.
OPTIMUM FIELD CONDITIONS
For the reliability and better life of the product the unit has to be operated at moderate
temperatures and humidity. The meter is designed to work from -5 to 60 degree C and
humidity of 95% RH non condensing.
STORAGE
In case if the meter is not installed after receiving, it has to be stored in a dry place in the
original packing material.
MOUNTING
Figure shows the location of the meter mounting holes. The Mount the Prepaid Energy Meter in
a dry location free from corrosive vapours. To mount the Unit: In the real panel side we have wall
mountable clamp, by using that mount the prepaid meter on the wall.
Fig. 1: Drawing for Single phase mo nting details

UM/SWHM/V3/0115
Fig. 2: Drawing for Three phase Mo nting details
Mo nting: The front bezel of the basic model is molded plastic. Bezel dimensions are 160 x
112 mm (Depth 58mm behind bezel) for single phase prepaid meter and 1 3 × 262 mm (Depth
82mm behind the bezel) for three phase prepaid meter.
EXTRA PRECAUTIONS
Make sure of supply voltage, supply current and configuration. Wrong connection can severely
damage the instrument, which is not covered under our warranty.
We recommended installing necessary protective device along with the meter like circuit
breaker / Fuse/ MCB/ Switch/ Isolator to take care of unexpected faults.
CONNECTION
The meter uses a polycarbonate casing and so is a good insulator. Hence it DOES NOT HAVE
ANY EARTH TERMINAL.
Terminal cover is to be used to protect the meter terminals from being tampered with. As soon
as the connections are made the terminal block has to be covered and sealed by terminal
cover. It can be fixed using two sealable screws.
VENTILATION
No specific ventilation is recommended. Meter is capable of working satisfactory at Ambient
between -5 to 60 degree C.
2.2. WIRING THE PREPAID METER
The inputs to be connected to the Prepaid Energy Meter are clearly indicated on the Front Panel.
Connect the Voltage inp ts: For LT Models (415 V AC L-Nominal), connect the voltage inputs
directly to the terminals. For HT Models, the inputs should be from the secondary of the Potential
Transformer. In a 3-wire system, the Neutral terminal is not connected. In a 4-wire system, the
neutral may or may not be connected to the terminal marked ‘N’.

8 UM/SWHM/V3/0115
Connect the C rrent inp ts: It is important to maintain the direction of the current flow from S1
to S2. If this reversed in one or more phases, the Power computation will be negative in the
corresponding element(s). Though the computation is internally corrected to an equivalent
positive value, it is not advisable to leave a reversal of current flow uncorrected.
It is important to adhere to phase relationships. Current ‘IR’ must correspond to the phase
that has the Voltage connected to the ‘VR’ terminal. The same holds good for current inputs ‘IY’
and ‘IB’. If the current and voltage inputs are swapped, the Power and Energy computations may
be erroneous.

Wire the D al Inp t
The Unit is capable of monitoring electricity consumed from two separate sources. One of these could
be the supply from the electricity authorities while the other could be from the in-house generator. For the
meter to recognize that the supply is from the alternate source, the meter requires a voltage input
between 240 V AC that should go live when the supply is from the alternate source as shown in Fig 2.
Wire the Digital Inp ts (Max.4)
Integration of Gas and Water with the electrical parameters thereby, extending the flexibility for the
user to budget expenses. The four digital inputs, any gas and water meter can be configured. It is
important to program the price / Pulse in the corresponding ElNet PPS.

4. PREPAID METER OPERATION
The meter is suitable for Three-phase four wire (PE5120)/ Single Phase 2 wire system (PE5121).
Meter measures electrical energy consumed and decrements the available credit register in accordance
with the energy consumption-KWh or kVAh. The available credit register is incremented as and when
payment is made. Meter continuously calculates the balance credit against the consumption.
As the balance credit decreases beyond the pre-defined level, a switch (latching relay) is used to
disconnect the supply to the load. Meter display starts blinking when the credit balance falls to a
programmed value.
Over voltage (OVER.VOL) Tripping: This is the unique feature from the Elmeasure meter to protect the
equipment when the over voltage occurs. When the Line voltage is more than programmed value the
prepaid meter trips the load, thus protecting the house hold equipments. This replaces the need for
over voltage relays in individual houses.
Over.KVA (EB or DG): Elmeasure meters have the unique feature to program the set limit for
consumption when it is operating on EB and DG in terms of kVA. When the consumption is above the
set value then the LOAD gets disconnected for a span of 1 minute (programmable through
configuration) after which the LOAD gets connected for the SET DELAY time to see the load is reduced
and if the consumption is still higher it trips the load for the 2
nd
delay time (programmable) and this
process gets repeated with the different programmable delay time until the consumption is reduced.
DG SELECTION: Elmeasure prepaid meter has great optional feature i.e. individual phases on for DG (R,
Y, B or RYB or No DG). This feature can avoid ACCL to individual houses.
