SAFETY PRECAUTIONS
All safety related codifications, symbols and
instructions that appear in this operating manual or on
the equipment must be strictly followed to ensure the
safety of the operating personnel as well as the
instrument.
If the equipment is not used in a manner specified by the
manufacturer it might impair the protection provided by the
equipment.
Do not use the equipment if there is any mechanical
damage.
Ensure that the equipment is supplied with correct
voltage.
1. Read complete instructions prior to installation and
operation of the unit.
2. Risk of electric shock.
3. The equipment in its installed state must not come in close
proximity to any heating sources, steam, caustic vapors,
oils or other unwanted process by products.
1. This equipment, being built-in-type, normally becomes a
part of main control panel and in such case the terminals do
not remain accessible to the end user after installation and
internal wiring.
2. Conductors must not come in contact with the internal
circuitry of the equipment or else it may lead to a safety
hazard that may in turn endanger life or cause electrical
shock to the operator.
3. Circuit breaker or mains switch must be installed
between power source and supply terminals to facilitate
power ‘ON' or ‘OFF’ function. However this switch or
breaker must be installed in a convenient position normally
accessible to the operator.
4.
5. The equipment shall not be installed in environmental
conditions other than those mentioned in this manual.
. The equipment does not have a built-in-type fuse.
Installation of external fuse of rating 275V AC / Amp for
electrical circuitry is highly recommended.
Before disconnecting the secondary of the external current
transformer from the equipment, make sure that the current
transformer is short circuited to avoid risk of electrical
shock and injury.

/ battery
INSTALLATION GUIDELINES
1. To prevent the risk of electric shock, power supply to the
equipment must be kept OFF while doing the wiring
arrangement.
2. Wiring shall be done strictly according to the terminal
layout. Confirm that all connections are correct.
3. Use lugged terminals.
4. To reduce electromagnetic interference use of wires with
adequate ratings and twists of the same in equal size shall
be made with shortest connections.
5. Layout of connecting cables shall be away from any
internal EMI source.
6. Cable used for connection to power source, must have
a cross section of 1.5mm . These wires shall have
currentcarryingcapacity of 6A.
7. Before attempting work on device, ensure absence of
voltages using appropriate voltage detection device.

MAINTENANCE
1. The equipment should be cleaned regularly to avoid
blockage of ventilating parts.
2. Clean the equipment with a clean dry or damp cloth.
Do not use any cleaning agent other than water.

verification as well as visual indication of energy
integration. The pulse rate is 1000 Pulses/kWh.

RESOLUTION :
SAFETY PRECAUTIONS
All safety related codifications, symbols and
instructions that appear in this operating manual or on
the equipment must be strictly followed to ensure the
safety of the operating personnel as well as the
instrument.
If the equipment is not used in a manner specified by the
manufacturer it might impair the protection provided by the
equipment.
Do not use the equipment if there is any mechanical
damage.
Ensure that the equipment is supplied with correct
voltage.
1. Read complete instructions prior to installation and
operation of the unit.
2. Risk of electric shock.
3. The equipment in its installed state must not come in close
proximity to any heating sources, steam, caustic vapors,
oils or other unwanted process by products.
1. This equipment, being built-in-type, normally becomes a
part of main control panel and in such case the terminals do
not remain accessible to the end user after installation and
internal wiring.
2. Conductors must not come in contact with the internal
circuitry of the equipment or else it may lead to a safety
hazard that may in turn endanger life or cause electrical
shock to the operator.
3. Circuit breaker or mains switch must be installed
between power source and supply terminals to facilitate
power ‘ON' or ‘OFF’ function. However this switch or
breaker must be installed in a convenient position normally
accessible to the operator.
4.
5. The equipment shall not be installed in environmental
conditions other than those mentioned in this manual.
. The equipment does not have a built-in-type fuse.
Installation of external fuse of rating 275V AC / Amp for
electrical circuitry is highly recommended.
Before disconnecting the secondary of the external current
transformer from the equipment, make sure that the current
transformer is short circuited to avoid risk of electrical
shock and injury.

/ battery
INSTALLATION GUIDELINES
1. To prevent the risk of electric shock, power supply to the
equipment must be kept OFF while doing the wiring
arrangement.
2. Wiring shall be done strictly according to the terminal
layout. Confirm that all connections are correct.
3. Use lugged terminals.
4. To reduce electromagnetic interference use of wires with
adequate ratings and twists of the same in equal size shall
be made with shortest connections.
5. Layout of connecting cables shall be away from any
internal EMI source.
6. Cable used for connection to power source, must have
a cross section of 1.5mm . These wires shall have
currentcarryingcapacity of 6A.
7. Before attempting work on device, ensure absence of
voltages using appropriate voltage detection device.

its place by fitting the clamp on the rear side. fit clamps on
both sides in diagonally opposite location for optimum

MAINTENANCE
1. The equipment should be cleaned regularly to avoid
blockage of ventilating parts.
2. Clean the equipment with a clean dry or damp cloth.
Do not use any cleaning agent other than water.
INT : The INT LED provides optical output for calibration
verification as well as visual indication of energy
integration. The pulse rate is 1000 Pulses/kWh.
X10 : X10 LED ON when the resolution is 10. It is the
indication of count reading which must be multiplied by
10 to get actual kWh consumed.
REV : REV LED gives the indication of reversal of two
or more CT connections presence of
In such cases meter may not
indicate the correct energy consumption. The CT shoul
be connected to the meter with correct polarities

Pulse output from EM306A meter can be interfaced
into a process through a PLC for on line control of
energy content in the process.
If the PLC has a self excited digital input, external DC
supply is not needed.
The kWh pulse is also used to derive average kWh
information at the PLC.
Pulse output from EM306A meter can be used as
alarm generator or total energy controller by
interfacing it with Pre-settable counter and control
circuits (Contractors, Relay, Trip Circuit).
The counter is loaded with the maximum energy
consumption. When count reaches setpoint it
provides output to control circuit to take appropriate
action.
