Introduction
The multifunction energy analyzer SMART ANALYZER series is a top new-generation intelligent panel meter, used not only in
the electricity transmission and power distribution system, but also in the power consumption measurement and analysis
in high voltage intelligent power grid.
This document provides operating, maintenance and installation instructions for the SMART ANALYZER series. The unit
measures and displays the characteristics of single phase two wires, three phase three wires and three phase four wires
supplies, including voltage, frequency, current, power and active and reactive energy, imported or exported, Harmonic,
Power factor, Max. Demand etc. Energy is measured in terms of kWh, kVArh. Maximum demand current can be measured
over preset periods of up to 60minutes. In order to measure energy, the unit requires voltage and current inputs in addition
to the supply required to power the product. The requisite current input(s) are obtained via current transformers The SMART
ANALYZER can be configured to work with a wide range of CTs, giving the unit a wide range of operation. Built-in interfaces
provide pulse and RS485 Modbus RTU outputs. Configuration is password protected.

1.5 Pulse output
Two pulse outputs indicate real-time energy measurement. Pulse output 1 is configurable, pulse output 2 is fixed to active
energy, 3200imp/kWh.
2.Start up screens
The first screen lights all LED segments and can be used as a display LED check
The second screen indicates the software version of the unit.
(the left picture is just for reference)
The unit performs a self-test and the screen indicates if the test is passed.
After a short delay, the default measurement screen appears.

6. Maintenance
In normal use, little maintenance is needed. As appropriate for service conditions, isolate electrical power, inspect the unit
and remove any dust or other foreign material present. Periodically check all connections for freedom from corrosion and
screw tightness, particularly if vibration is present.
The front of the case should be wiped with a dry cloth only. Use minimal pressure, especially over the viewing window
area. If necessary wipe the rear case with a dry cloth. If a cleaning agent is necessary, isopropyl alcohol is the only
recommended agent and should be used sparingly. Water should not be used. If the rear case exterior or terminals should
be contaminated accidentally with water, the unit must be thoroughly dried before further use. Should it be suspected
that water might have entered the unit, factory inspection and refurbishment is recommended.
In the unlikely event of a repair being necessary, it is recommended that the unit be returned to the factory or nearest
distributor.

7 Installation
The unit may be mounted in a panel of any thickness up to a maximum of 3 mm. Leave enough space behind the
instrument to allow for bends in the connection cables. The unit is intended for use in a reasonably stable ambient
temperature within the range -25°C to +55°C. Do not mount the unit where there is excessive vibration or in excessive
direct sunlight.
7.1 Safety
The unit is designed in accordance with IEC 61010-1:2010 – Permanently connected use, Normal condition. Installation
category III, pollution degree 2, basic insulation for rated voltage.
7.2 EMC Installation Requirements
Whilst this unit complies with all relevant EU EMC (electro-magnetic compatibility) regulations, any additional precautions
necessary to provide proper operation of this and adjacent equipment will be installation dependent and so the following
can only be general guidance:
Avoid routing wiring to this unit alongside cables and products that are, or could be, a source of interference.
The auxiliary supply to the unit should not be subject to excessive interference. In some cases, a supply line filter may be
required.
To protect the product against incorrect operation or permanent damage, surge transients must be controlled. It is good
EMC practice to suppress transients and surges at the source. The unit has been designed to automatically recover from
typical transients; however in extreme circumstances it may be necessary to temporarily disconnect the auxiliary supply
for a period of greater than 10 seconds to restore correct operation.
Screened communication leads are recommended and may be required. These and other connecting leads may require
the fitting of RF suppression components, such as ferrite absorbers, line filters etc., if RF fields cause problems.
It is good practice to install sensitive electronic instruments that are performing critical functions in EMC enclosures that
protect against electrical interference causing a disturbance in function.

During normal operation, voltages hazardous to life may be present at some of the
terminals of this unit. Installation and servicing should be performed only by qualified,
properly trained personnel abiding by local regulations. Ensure all supplies are deenergized before attempting connection or other procedures.
Terminals should not be user accessible after installation and external installation
provisions must be sufficient to prevent hazards under fault conditions.
This unit is not intended to function as part of a system providing the sole means of
fault protection - good engineering practice dictates that any critical function be
protected by at least two independent and diverse means.
The unit does not have internal fuses therefore external fuses must be used for
protection and safety under fault conditions.
Never open-circuit the secondary winding of an energized current transformer.
This product should only be operated with CT secondary connections Earthed.
If this equipment is used in a manner not specified by the manufacturer, protection
provided by the equipment may be impaired.

Auxiliary circuits (communication & relay outputs) are separated from metering inputs and
110-400V auxiliary circuits by at least basic insulation. Such auxiliary circuit terminals are only
suitable for connection to equipment which has no user accessible live parts. The insulation
for such auxiliary circuits must be rated for the highest voltage connected to the instrument
and suitable for single fault condition. The connection at the remote end of such auxiliary
circuits should not be accessible in normal use. Depending on application, equipment
connected to auxiliary circuits may vary widely.
