Handling
We recommend the correct handling through compatible equipment with its
dimension and weight.
The package is fit for use with trans-pallet carts, or hoisted through a Munk type
truck with the aid of suitable belts, or with the use of trucks fitted with a lifting
platform.
The voltage regulator, despite its size and weight which, depending on the model
can assume higher value, is a sensitive electronic piece of equipment, bearing
power subassemblies and electronic boards with micro controller circuits,
processors and liquid crystal display that can suffer irreparable damage due to
handling.
We recommend the maximum care possible not to damage the external parts such
as the front panel, duly identified in the package, as well as side, top and rear
covers.
Most voltage regulators are endowed with self sustaining casters for easy handling,
however, they are potential points for damage when not handled appropriately. We
recommend maximum attention during the move.
We remind you that any damage due to incorrect handling, as well as any physical
damage to the cabinet and painting, will not be covered by the warranty.

Installation
Preparation –Choice of local and environment setting
The Premium Perfection Series Voltage Regulator is strongly built and may
function under diverse conditions, however, the choice of the installation place will
influence very much on the life of the components and frequency of maintenance.
The shelter area must be clean, free of dust, corrosive gases, sea-side air,
humidity, drippings and suspended conductive particles.
The area around the equipment, especially its base, sides and ventilation outflow,
must be clear of objects that may obstruct the input and outflow air.
The cleaning of the floor beneath the humidity must be done with a vacuum
cleaner, broom or brush, and must only be done after interrupting the voltage
regulator electric power.
Check if the floor is compatible and supports the weight of the unit. Refer to the
Physical Dimensions Table in the Technical Specifications chapter in this manual.
Good lighting, easy access to the area and provision of physical space, will ensure
easy access to the internal components, and it must be taken into consideration in
order to facilitate any technical interventions and reduce MTTR –Medium Time to
Repair.
On the other hand, unfavorable environments, with difficult access to technical
personnel, increase MTTR or even hinder such tasks.
The recommended the ambient temperature be from 20º C to 25º C under low
relative humidity.
The methods to suit the ambient temperature where the voltage regulator will be
installed can be:
- Natural Ventilation: applicable when the environment is kept under the desired
limits.
- Forced Ventilation: applicable only when the outer temperature is lower than the
room where the voltage regulator will be housed.
- Air Conditioning: applicable when the outer temperature is higher than the
room where the voltage regulator will be housed.

Positioning
At the time of positioning the voltage regulator, consider the following factors:
A minimum space of one meter front wise from the equipment for access to the
frontal panel and operational commands.
A minimum space of 40 centimeters between the back of the voltage regulator and
the wall so as not to obstruct the inner exhaust fan air flow. For models with 20 kVA
maximum power, the free space for the upper part must be considered in 40
centimeters.
We recommend objects not to be placed onto the voltage regulator. The cable
entry must be done by using flexible auto-type cables only. For gauges above 25
mm2, we recommend the use of welding type cables, or similar.
The cable plumb must be sized considering a minimum gap of 1.5 meters between
the exit point of the cables from the bed to the equipment terminal block.
For places with difficult access and lateral space below 1.0 meter, we recommend
to double the size and length of the cables, thus facilitating the forward
displacement of the voltage regulator freeing the access to the inner parts.
The connecting terminals from the voltage regulator input and outlet cables are
located in the frontal lower part. Consider a height of 30 cm between the floor and
the connecting terminals, besides the needed gap of 2.0 to 4.0 meters for the whip
as from the recommended above.
Note.: For models with power up to 20KVA the air exhaust is done from the rear
part. Above 20KVA the air exhaust is done from the upper part.

Microprocessed Voltage Regulator
Three-Phase Perfection Premium Series
User´s Manual
CM COMANDOS LINEARES - 20/38 -
The electronic voltage regulators were developed by CM to meet the most
sophisticated and demanding consumers. The main characteristic is to withstand
great load variations –0 to 100% - in extremely short periods of time –in the
millisecond order, keeping the output absolutely stable, within 1%.
Moreover, this model has a wide range of input variation, 16% of overvoltage and
16% undervoltage, assuring extremely high performance in any work range.
The correction time for electric power variations exceeds all previous expectations,
being inferior to 4.0 milliseconds.
The project was developed so as to reach a high yield, taking into consideration
the best MTBF.
In the project, every automatic internal command was considered, dismissing the
intervention of the operator as, for instance, the undervoltage and overvoltage
system with automatic reset.
Stabilization Principle
The Perfection Premium Series Voltage regulator uses sophisticated IGBT
modules which generate the wave form needed to correct the electric supply
voltage variations. The result is a precision rate on the output voltage of +/- 1%,
due to its linear correction system, without the use of taps or voltage steps.
The output voltage adjustment takes place through the compensation transformer
automatic key, so as to add or subtract minute voltage values thus influencing the
voltage regulator output voltage.
The voltage regulator is highly stable for any load level and/or input voltage, even
with sudden variations of +/- 16% in the input and 0 - 100% of load; the output
voltage remains constant and invariable in time. The reference voltage for the
regulation circuit and control maintain stable, overall for ambient temperature
variations within the normal specified range, according to the technical
characteristics.
The regulation circuit and control have appropriate filters and other needed
elements in order to ensure the output voltage stability for all adverse conditions.
After the occurrence of any transitory character disturbance (non-oscillatory), either
on the input voltage or on the load, the output characteristics will return to the
stable status within the criteria established for any dynamic regulation of the
voltage.
