CHAPTER 1 ─ INTRODUCTION
1.1 About the ElNet Pico Powermete
Large consumers of electricity e.g. factories, hotels, hospitals,
municipalities, need to know the history of their consumption and
the quality and the values of the power supply. Details such as
Voltage, Current, Power Factor, Hertz, Neutral Current, Energy
consumption can be displayed by the ElNet Pico Energy
Powermeter .
An additional feature of the Multimeter is the ability to measure
THD –Total Harmonic Distortion. Part of the Electricity Supply
Authority’s bill reflects poor or good Harmonics in the
consumer’s system, therefore it is in his interest to monitor
Harmonics and try to improve it.
The ElNet Pico Energy Powermeter is a compact, multi
functional, three-phase Powermeter simple to install and is
especially designed to integrate into Building Management
Systems. It requires no special mounting and is ideally suited for
mounting on DIN rail of any standard electrical panel.
The Configuration and Setup is menu driven, with password
protection.
Communication with external devices is simple and is based on
standard known protocol.
Each ElNet Pico Energy Powermeter is carefully and
meticulously manufactured using quality components and the
latest production methods. Before leaving the factory each
ElNet Pico Energy Powermeter is calibrated and is sent
to the customer accompanied by the test certificate and Certificate
of Compliance (C.O.C).

the above mentioned tasks can be combined, or in a rare instance
one person could handle all three tasks.
CHAPTER 1, Introduction, describes the ElNet Pico
Powermeter , its potential users, the readings it can provide and
some of its features in brief.
CHAPTER 2, Installation, provides detailed instructions for
unpacking, mechanical mounting, and electrical wiring up
instructions for the Installation Technician.
CHAPTER 3, Using the ElNet Pico Powermeter, describes
in detail front Panel, the functions of the control buttons, and the
Lock Utility.
CHAPTER 4, Parameter Configuration & Settings explains in
detail the minimum parameters settings needed by the Senior
Electrical Engineer to set up and configure the ElNet Pico
Energy Powermeter.

7
CHAPTER 5, Front Panel Displays, is an easy to follow step-by-
step guide to obtain readings and tables.
CHAPTER 6, Communications provides details about the
Communication capabilities of the ElNet Pico Energy
Powermeter, and how to Set Up.
CHAPTER 7, Specifications, is a detailed list of specifications of
the ElNet Pico Energy Powermeter.
1.3 Safety Information
The purpose of this manual is to help you. Please read the
instructions carefully before performing any installation and note
any precautions.
Ensure that all incoming AC power and other
power sources are turned off before
performing any work on the ElNet Pico
Energy Powermeter. Failure to do so may
result in serious or even fatal injury and/or
equipment damage.
If the ElNet Pico Energy Powermeter
is damaged in any way do NOT connect it to
any power source.

2.4 Connections
To connect the ElNet Energy Powermeter
All Connections are made via terminal connector plugs (Voltage
input, Power Supply, etc.).
Recommended max. tightening torque for the connector screws is
0.5 Nm.
The CT cores of the ElNet Energy Powermeter are located
internally in the instrument and the lead from the leg of the
external Current Transformer must be connected to the correct
terminal connector in order to maintain the correct direction.
NOTE!
Ensure all the connections to the leads of the current
transformer wiring is secure and there is no mechanical
strain on the wire
Connect the lead from side “L” to the terminal connector L at the
relevant phase, than connect the lead from side “K” to the
terminal connector K at the same phase, of the ElNet Energy
Powermeter.

18
WARNING!
WARNING
Never allow an open circuit between the two Current
Transformer leads.
Repeat the procedure for Line 2 and Line 3.
Connect the rest of the connections to the ElNet Pico Energy
Powermeter by means of terminal connector plugs.
The Front Panel (See Figure 2.3)has all connections printed and
is simple to follow. (See table 2.1 for connections).
