ACTIVE AND REACTIVE ENERGY METER
Read all the instructions carefully
The ENERGY-400 PAR is a electronic static device to read active and reactive energy in
three-phase systems designed to operate in environments with measurement category III and
pollution level 2 according to EN 61010-1 standard.
SAFETY WARNINGS
To guarantee correct installation, proceed as follows:
1) The appliance should be installed by a qualified operator
2) The appliance should be installed in a panel in such a way as to guarantee that the
terminals are inaccessible after fitting
3) A protection device against over-currents should be installed in the electrical system,
upstream of the energy meter
4) Connect the instrument as shown in box B)
5) Before touching the connector terminals make sure that the wires to be connected or
already connected to the instrument are not live
6) Touch the dip-switches only when the instrument is not powered
7) Do not power or connect the instrument if any part of it is damaged
8) The instrument must be installed and activated in compliance with current electric
system standards.

INSTRUMENT DESCRIPTION
Dip-switch for CT setting
: lights up to indicate power onGreen warning light
Two red warning light: flashes to indicate that the instrument is metering energy
(1 flash = ΒΌ kWh or ΒΌ kvarh)
Yellow warning light: when lit the instrument detects ΒΌ kWh negative (probable
incorrect entry) and remains lit until ΒΌ kWh positive is detected
Check the insertion of CT: connect L1, L2, L3 from power panel to P1 of CT and
connect P2 of CT to the load.
Impulse output: Optically insulated
Two electro-mechanical impulse counters: resolution 1 kWh or 1 kvarh
GUIDE TO INSTALLATION
1) Before installing the instrument, select the CT transformation ratio, as shown in the
diagram in box (C)
2) The amperometrical measure terminals are galvanically insulated, therefore the CT
secondary circuit may be connected to earth
3) (B) The instrument should be connected as shown in box in accordance with the CT
current directions
4) If the error is to fall within the class limits of the instrument, it is necessary to use the
current transformer in its linear operating field.

5) If the instrument is active the power should be switched off to change the CT ratio.
6) In case of changes to the dip-switch with the instrument actived, these locks in fault
condition with red and green lights always on. In this condition the instrument doesn’t
coun.
To restore the correct operation, reposition the DIP switches in the initial condition or
reset the instrument by removing and restoring power.
