5. INSTALLATION.
Read and respect the Safety Information, described
•
in section 2 of this document. To obviate some of
the indications described in it, can cause serious or very
serious injuries to the persons in direct contact or in the
vicinity, as well as faults in the equipment and/or loads
connected to itself.
Check that data in the nameplate are the required ones by
•
the installation.
A wrong connection or manoeuvring, can cause faults in the
•
stabilizer and/or loads connected to it. Read the instruc-
tions of this manual carefully and follow the stated steps in
the established order.
The equipment must be installed by qualified personnel
•
and it can be used by personnel with not specific
training, just with only help of this «User's manual».
Any connection of the equipment, including the con-
•
trol (interface, remote control, ...), will be done with
all the switches in rest and no mains present (power supply
switch of the equipment turned «Off»).
5.1. TO CONSIDER IN THE INSTALLATION.
The equipments have terminals for its input and output
•
connections. Nevertheless some models due to their high
power rate, the power supply cable connection is directly
done in the own terminals of the input switch or breaker,
when they have rods.
As regards to the protective earth connection and earth
•
bonding connection, the equipments have an earth ter-
minal or stud, less those double cabinets, which will have
two earth connection points by means of studs, one for the
main protective earth cable and the other one for the earth
bonding for the load or loads.
For the equipment communication, it is supplied a RS232
•
port with DB9 connector and the Slot for the SICRES Eth-
ernet card.
As an option, it is available other communications ways:
2 dry contacts of alarm from the LCD panel connected
ˆ
to a terminal strip.
Communication module, which includes up to 2 serial
ˆ
ports, 9 programming dry contacts, 1 analogical input
and another one digital. For more information see docu-
ment EN030*00.
The nameplate of the equipment contents the maximum
•
input current (corresponding to the nominal power with low
voltage regulation) and the nominal output. The efficiency
of the equipment has been considered to calculate the
input current.
Overload condition is considered as a nonpermanent and
exceptional way.
In case peripheral elements are added at the input or output
•
like transformers or autotransformers, The current of the
64
nameplates of these elements has to be considered in order
to select the suitable cross cable section, by respecting the
Local and/or National Low Voltage Electrotechnical Regula-
tions.
Regarding the size of the terminals of the built switches
•
in the protection panel, the cross cable section has to be
considered, in order to leave them completely embraced in
all its section, in order to have an optimal contact between
both elements.
It is compulsory that the line that supplies the stabilizer
•
includes the input protection, which allows to break it to
make the connection tasks with no voltage, otherwise it
could mean a danger of the fitters.
It is recommended to equip the installation with a switch-
gear protection panel, which besides of the input protec-
tion, it has an output protection and manual Bypass switch.
Under request, it can be supplied or you can opt for manu-
facturing it by yourself by following the information stated
in the documentation Pendrive.
The start up and shutdown operating instructions are
described in the user's manual, considering that the in-
stallation is provided with a complete panel like the rec-
ommended one. If it is not available omit the protection or
switch manoeuvring.
The documentation supplied together with this us-
•
er's manual and/or in the Pendrive, and the informa-
tion regarding the «Recommended installation» can be
checked. This information shows the wiring diagram, pro-
tection sizes and minimum connecting cross cable sections,
attending to the nominal operating voltage of the equip-
ment. All the values are calculates for a maximum cable
length of 30 m between the protection panel, equipment
and loads.
For higher lengths correct the cross sections in order to
ˆ
avoid dropping voltages, in accordance with the par-
ticular Regulations or norms of the country.
The size and type of the protection to install will be
the stated in the information related to «Recom-
mended installation», supplied together with this user's
manual in the documentation Pendrive.
The neutral regimes of the input and output are identical for
•
the EMi3 stabilizers «with no galvanic isolation».
When, as an option, an equipment incorporates a gal-
•
vanic isolation transformer, which can be built in from
factory or by your own, either at the input or output of the
equipment, protections for indirect contact must be fitted in
(RCD) at the output of each transformer, because in case of
electrical shock in the secondary winding, due to its isolation
feature, it will impede the tripping of the protections located in
the primary of the transformer (isolation transformer output).
We remind you that any isolation transformer fitted in
•
or supplied from factory, has the output neutral earthed
through a cable that joints the neutral an PE terminals. If
an isolated output neutral were needed, this cable bridge
must be removed, by taking the needed cautions as regards
to the local and/or national regulations.
