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.

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.
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
