• All power supply electrical cables have to be fixed to the equip-
ments and loads, interfaces, etc..., to immovable parts and in
the way to avoid step on it or go through them with an transport
medium or expose them to fortuitous pulls.
• Be careful to not wet it, because it is not waterproofed. Do not
allow entering any kind of liquids in, otherwise shutdown it im-
mediately and contact with the
(S.T.S.)
.
• If the enclosure of the equipment is in contact with liquids or
high density saline air accidentally, dry it with a soft and absor-
bent cloth quickly.
Check that no liquid has entered inside the unit and act accord-
ingly.
• To clean the equipment, wipe over a damp cloth and then dry it.
Avoid liquids sprinkling or spillage that could enter through the
slots or cooling grids, which may cause fire or electric shock.
Do not clean the equipments with products that could have al-
cohol, benzene, solvent or other inflammable substances, and
even if they are abrasive, corrosive, liquids or detergent.
• Never manipulate the equipment with wet hands.
• If it is observed that the UPS exhausts smoke or toxic gas, shut-
down it immediately and disconnect it from power supply. This
kind of fault can cause fire or electrical discharge. Contact with
our
(S.T.S.)
.
• Do not put either materials or parts over the equipment that
obstruct the correct visualization of the synoptic.
•
Before using the UPS for first time or after a long period
of time (6 months maximum), it has to be connected to
the power supply to charge the batteries for a minimum period
of time of 12 hours.
Although the equipment can operate with batteries discharged,
it has to be kept in mind the possible risk of mains fault during
the first operating hours, so the available back up time in the
UPS batteries, can be lower than the expected.
2.2.2. General safety warnings.
• All electrical connections and disconnections of cables from
the equipment, including the control ones, will be done with no
power supply and switches on rest position «O» or «Off».
•
Pay special attention to the labelling of the equipment
that warns about the «Electrical shock hazard», inside
the equipment there are dangerous voltages.
Do not open, dismantle or modify the equipment, if this action
is not stated in this document. To manipulate inside the equip-
ment for repairing is restricted to
qualified
staff only. In case of
maintenance or fault, consult to the closest
(S.T.S.)
.
A part from the implicit risk of electrical shock, any action that
make the modification, internal or external of the equipment
or just only the simple intervention inside of itself, which is not
stated in this document,
it can expire the warranty
.
• During the erection and commissioning operations is needed to
open the front door and some models is required to remove the
protection cover from terminals too.
Once the respective actions are finalised, leave the equipment as
it was, with the protection cover put back and front door closed.
• To shutdown the equipment completely, follow the instructions
in the start up and shutdown chapter.
Consult the documentation before doing any action. A
wrong manipulation over the switches can cause impor-
tant production losses and/or failures in the equipments.
•
Protection Earth cable of the UPS drives the leakage current
of the load devices. An isolated earth cable has to be in-
stalled as part of the circuit that supplies the equipment. Cross cable
section and its features will be the same as the power supply cables,
but with green colour with or without the yellow strip.
•
The protection earth must be connected to the frame or
metallic chassis of any electrical equipment, by means
of the foreseen terminal (in our case to the UPS, battery cabinet
when it is available and loads), assuring that it is done before
turning on the input voltage.
It is essential that cables that feed the loads have their respective
protection earth cable.
When branch circuits are made, i.e. by means of terminal strips,
it is essential to have a protection earth terminal in each one
of them.
• Check the quality and availability of the earth, it has to be between
the defined parameters by the local or national regulations.
•
During the normal UPS operation, the input power supply
cable can’t be disconnected, because the general protec-
tion earth cable of the own UPS and all loads connected at the
output will be disconnected too.
Due to the same reason, the general protection earth cable of
the building or switchgear panel that supplies the UPS will not be
disconnected.
• Cross cable sections used to supply the equipment and loads to be fed,
will be according to the nominal current stated in the nameplate label of
the equipment, and respecting the Low Voltage Electrotechnical Regu-
lations or standards of the country.

CUBE3+
equipments can be manufactured in four different
configurations of Input-Output:
Three phase - Three phase.
Three phase - Single phase.
Single phase - Three phase.
Single phase - Single phase.
For the correct operation of the UPS, it is needed the input Neu-
tral cable or in case of its missing, it has to be created by means
of an isolation transformer located between the power supply
and the equipment.
• The UPS doesn’t modify the input neutral regime at its output.
Do not earth the output neutral.
When, it is needed to modify the output neutral regime, an iso-
lation transformer has to be located between the loads and the
equipment.
•
In those models with separate bypass line, an isolation
transformer has to be located in any of both input lines
(rectifier input or static bypass), in order to avoid the direct con-
nection of the neutral of both lines through the internal wiring of
the equipment.
This is only applicable when the two power supplies come from
different lines, i.e.::
Two different electrical companies.
One electrical company and a generator, ...
• La The installation will have input protections sized to the cur-
rents of the equipment and stated in the nameplate label (RCD
