for power. Other connections are made through connectors,
including connection of the device to the battery module.
Thermal control of these devices is carried out with the
•
passage of forced air from the front to the rear.
The front surface and about 15 cm on the rear side should be
left free of obstructions to facilitate the free circulation of air
for ventilation.
Protection board:
•
It will have a type-B differential circuit breaker and a short
circuit protection (C-curve circuit breaker) for the UPS's input
line.
As for size, they will be at least the current indicated on the
nameplate of the UPS.
Only the rated current as indicated by the EN-IEC 62040-1
•
safety standard is printed on the nameplate of the device. For
the calculation of the input current, the power factor and the
equipment's own performance have been considered.
Overload conditions are considered a non-permanent and
exceptional working mode.
The cross section of the input line cables is determined
•
by the current indicated on the nameplate of each device,
in compliance with local and/or national Low-Voltage
Electrotechnical Regulations.
If peripheral input and/or output elements, such as
•
transformers or autotransformers, are added to the UPS, the
currents indicated on the nameplates of these elements must
be taken into consideration when determining appropriate
cross sections, in compliance with local and/or national Low
Voltage Electrotechnical Regulations.
When a device incorporates a galvanic isolation
•
transformer as an optional extra or installed
independently, either at the input, output or both, it must be
fitted with protection against indirect contact (differential
circuit breaker) at the output of each transformer, since, due to
its own insulation properties, it will prevent the tripping of the
protections placed on the primary of the isolation transformer
in case of electric shock on the secondary (output of the
isolation transformer).
We remind you that all the isolation transformers installed or
•
factory supplied, have the output neutral grounded through a
bridge between the neutral terminal and ground. If the isolated
output neutral is required, this bridge must be removed, taking
the precautions indicated in the respective local and/or
national low voltage regulations.
This device is suitable for installation in networks with
•
TT, TN-S, TN-C or IT power distribution systems, taking
into account at the time of installation the particularities of the
system used and the national electrical regulations of the
destination country.
All of the models in this series have an input polarity
•
detector (phase-neutral), which activates a modulated
audible alarm every 2 seconds and displays the message on
SF
the ' ' display in the event of a fault.
When the circumstance arises, disconnect the plug from the
mains socket and rotate it 180º.

If the same alarm condition is maintained, it will be a two-phase
power line signal or installation without neutral referenced to
earth. Contact our T.S.S. or the distributor before connecting
loads to the output.
The ADVANCE RT2 features terminals for the installation of an
•
external emergency power off button (EPO) or, failing that, a
single device must be installed to cut the power supply to the
loads in any operating mode.
5.1.5.7. Preliminary considerations before
connection, regarding the batteries and
their protections.
SPS.ADVANCE RT2 devices incorporate the batteries in the
•
same box as the device, except for B0 and B1 models.
The UPS's battery protection is internal by means of fuses and
is therefore not accessible to the user.
The battery modules have a circuit breaker accessible to the
user and a second internal protection consisting of a non-
accessible fuse.
IMPORTANT FOR SAFETY: If batteries are installed
•
independently, the accumulator group must be fitted
with a bipolar circuit breaker or disconnect fuse of the size
indicated in .
Inside the battery module, there are
•
with risk of electric shock, so it is classified as a RESTRICTED
ACCESS AREA.
Do not handle the battery circuit breaker when the
•
device is running.
If the mains power of the device is cut for longer than a
•
simple intervention and it is expected that it will be out
of service for a prolonged period time, the system must be shut
down completely.
The battery circuit is not isolated from the input
•
voltage. Dangerous voltages can occur between the
terminals of the battery group and the earth. Check that there
is no input voltage before working on the battery module con-
nectors.
5.2. CONNECTIONS.
A bad connection or operation can cause faults in the UPS
•
and/or the loads connected to it. Read the instructions in this
manual carefully and follow the steps indicated in the order
established.
The devices can be installed and used by personnel
•
without specific training by simply using this manual.
It should never be forgotten that a UPS is a generator
•
of electrical energy, and as such, the user must take all
necessary precautions against direct or indirect contact.
All of the device's connections, including those related
•
to control (interface, EPO, etc.), must be made without
mains power present and the UPS set to 'Off'.
To connect a device to an optional battery module, or between
•
modules, or to install an optional card in the slot, it is necessary
