Installation Guidelines
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. 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.
5. The equipment shall not be installed in environmental
conditions other than those mentioned in this manual.
6. The equipment does not have a built-in-type fuse.
Installation of external fuse of rating 275V AC / 0.5Amp for
electrical circuitry is highly recommended.
7. Remove the scratch-guard from the meter display during
commissioning of the panel.
Mounting distance
The distance to be maintained between two meters while
mounting on a panel door should be at least 100 mm.

Wiring Guidelines
Safety Precautions
Maintenance
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. Confi rm 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.
All safety related codifi cations, 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 specifi ed 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. 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.
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 1mm2to 2.5mm2.These wires shall have
current carrying capacity of 6A.
7. Copper cable should be used (Stranded or Single core
cable).
CAUTION:
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, oils, steam, caustic
vapors or other unwanted process by products.

{143 + [(Harmonic no-2) x 2] + 60 x Constant Parameter}
For Example,
To fi nd the 14th Harmonic address of Voltage V31 following
formula can be used:
Formula with the parameter:
{143 + [(Harmonic no-2) x 2] + 60 x C P}
Eg. {143 + [(14-2) x 2 ] + 60 x 5} = 467
So, Check the 14th Harmonic of Voltage V31 at 467 address.
