Installation and user instructions

Three-phase energy analyser for indirect connection (5A or 0.333V) with Modbus or pulse interface

The analyser measures active and reactive energy,

summing or separating imported energy from

exported energy. It displays the main electrical

parameters, including THD, calculated neutral

current and running hours. Current measurements

by external current transformers and voltage

measurements either direct or by potential

transformers. Equipped with a pulse output and

optionally with RS485 Modbus port. It measures

four DIN modules, with removable LCD display unit

allowing the same unit to be used either DIN-rail or

panel mounted and to be used as a transducer

without the display.

Cleaning

Use a slightly dampened cloth to clean the instrument display; do not use abrasives or solvents.

Service and warranty

In the event of malfunction, fault or for information on the warranty, contact ELCOMPONENT Ltd.

General warnings

DANGER! Live parts. Heart attack, burns and other injuries. Disconnect the power supply and load

before installing the analyser. The energy analyser should only be installed by qualified/authorised

personnel.

Intended use: measurement of electrical parameters, indoor use. Use it in installations with

overvoltage cat. III or lower.

These instructions are an integral part of the product. They should be consulted for all situations tied

to installation and use. They should be kept within easy reach of operators, in a clean place and in

good conditions.

Pay attention when removing the

instrument from the DIN rail in order to

avoid breakage of the support.

Excessive rotation of the instrument to

remove it, might break the support as

shown in the figure. We suggest extracting

downwards.

Procedure for adapting the mounting (Fig. 3)

It is possible to convert the type of instrument installation, from DIN to Panel (72x72) or vice versa,

thanks to the special removable front panel. The instrument without the front panel will have the

function of a transducer.

The table below advises the conversion process:

Step

Action

Unclip, using a screwdriver of appropriate size, the spring tabs (total of two) A pushing them

from the slots B.

Pull out the display unit

Insert the display unit into the side desired, according to the type of montage:

C- DIN rail

D- panel 72x72

Note: the package includes two mounting brackets for panel mounting of the instrument
