OP1029-V01
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
2 2 0
cross section of 0.5mm to 2.5mm ( 20 to 14AWG ; 75 C
(minimum)). These wires shall have current carrying
capacity of 6A.
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, oils, steam,
caustic vapors or other unwanted process by products.
CAUTION :
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
CAUTION :
For installing the meter
1. Prepare the panel cutout with proper dimensions as
shown below.
2. Push the meter into the panel cutout. Secure the meter
in its place by fitting the clamp on the rear side. Fit
clamps on both sides in diagonally opposite location for
optimum fitting.
3. For proper sealing, tighten the screws evenly with
required torque.
Terminal screw tightening torque :
0.68 N-m to 0.79 N-m ( 6.018 In-Lb to 6.992 In-Lb )
Screw clamp tightening torque : 0.1N-m (0.885 Lb-inch)
MECHANICAL INSTALLATION
7. Copper cable should be used.
(Stranded or Single core cable).
8. Before attempting work on device, ensure absence of
voltages using appropriate voltage detection device.
9. Recommended CT: Measuring type.

USER GUIDE
LED INDICATIONS
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.
EXP : EXP LED gives the indication of reversal of one or
more CT connections or presence of negative power in any
or all phases. In such cases meter may not indicate the
correct energy consumption. The CT should be connected to
the meter with correct polarities.
NOTE : For resetting active energy, user will be prompted the password. If correct password is entered, the user
will be able to reset all energy parameters. This password will be a value which will be greater than the configuration
password by 1.
Pulse output from 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 meter can be used as alarm generator
or total energy controller by interfacing it with Pre
settable counter and control circuits (Contactors, 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.
