To the user
We would like to thank you for choosing the SineWave™ active harmonics conditioner and welcome you to the ever increasing
world-wide family of satisfied MGE UPS SYSTEMS product users.
This manual has been written to provide you with all the information necessary to install and operate your SineWave™ active
conditioner.
We remain at your entire disposal should you require any further details.
MGE UPS SYSTEMS
Danger
Hazardous voltages are
present inside the
autotransformer.
Work on this equipment
should only be carried out
by qualified personnel.
◗ the autotransformer must be
earthed;
◗ do not install the autotransformer
near liquids or in excessively damp
environments;
Pictograms
Important instructions that must
be followed
Information, advice, help
◗ do not obstruct the air vents;
◗ do not place the autotransformer in
direct sunlight or near sources of
heat;
◗ if the autotransformer is to be
stored before use, it must be kept in
a dry, dust-free location.
Storage temperature: between 20+C and +45+C.

Installation of the SineWave™ active harmonics conditioner, its autotransformer for a 208 volt mains,
checking of its operation and certain repairs should only be carried out by qualified personnel trained to deal
with electrical hazards.
Other operations may be carried out by any other persons with the help of this manual.
All SineWave™ range products are protected by patents; they implement original technology which cannot
be used by any competitor of MGE UPS SYSTEMS.

Autotransformer for 208 volt mains
installation manual
Presentation
This document is complementary to the
SineWave™ installation and operation
manual. It provides additional
information required for the installation
and connection of the autotransformer
for adaptation to a 208 volt mains.
Typical diagram
The autotransformer must be
connected between the mains and the
SineWave™ active harmonics
conditioner.
The position of the sensors
and the connection point of the
SineWave™ active harmonics
conditioner may vary from one
installation to another depending on the
type of problem to be solved.
The optimum locations are determined
from the information gathered during
the assessment carried out on the site
before installation.
The autotransformer and the
SineWave™ unit are connected in
parallel with the load.
The SineWave™ active
harmonics conditioner must be
powered by a special circuit.
The autotransformer should be
protected by a circuit breaker and the
line supplying the SineWave™ unit by
fuses. The SineWave™ unit uses this
line to send harmonics intended to
compensate the load harmonics back
into the mains.

Cables (not supplied)
Autotransformer for 208 volt mains
installation manual (continued)
The cross-sectional areas of the cables
should be determined in compliance
with applicable standards using the
information in the table opposite and
the tables indicating the recommended
protective devices for the various
SineWave™ ratings.
If the neutral is distributed, it should be
sized to take into account the
predominant presence of the 3rd
harmonic that can lead to a current in
the neutral three times that of the
current in the phases.
Protective devices (not supplied)
The protective devices to be used
should be determined in compliance
with applicable standards using the
information below and respecting
discrimination constraints. Specific
models are cited only as a general
indication and do not engage the
responsibility of MGE UPS SYSTEMS.
The minimum cable crosssectional area can be
determined from the sizing
current (Is) given in the tables
below.

If protection is provided by
fuses, the fuse holder must be
of the open type to allow for
fuse cooling.
If the neutral is distributed,
it should be connected.

Autotransformer for 208 volt mains
installation manual (continued)
Connection procedure
Connection operations must
be carried out with the
equipment de-energised.
For the protection of
persons, always connect the
PE or PEN conductor first.
Earthing arrangement: SineWave™ is
suitable for all types of earthing
arrangements.
Autotransformer characteristics
Unless otherwise stipulated, the
performance data given in the table
below are typical values corresponding
to use under a nominal 3-phase 50 Hz
mains voltage of 208 volts and rated
current.
Procedure :
◗ make sure that the circuit breaker on
the circuit supplying the SineWave™
unit is in the "off" position ( O );
◗ connect the PE or PEN conductor
first;
◗ connect the other conductors, taking
care to respect the phase rotation
direction.

power cables or the autotransformer.
For the same reason, the power cables

near the terminal block to
prevent any mechanical
forces from being exerted on
the connections .
Note: If the cables are pulled, the PE
or PEN connection should be the last to
be subjected to the applied force.
