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.

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
1
Unclip, using a screwdriver of appropriate size, the spring tabs (total of two) A pushing them
from the slots B.
2
Pull out the display unit
3
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
