This device is suitable for installation in networks
with TT, Tn-S, Tn-C or IT power distribution sys-
tems, taking into account at the time of installation the
particularities of the system used and the national elec-
trical regulations of the destination country.
•
AdvAnCe R and T models feature terminals for the instal-
lation 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.
5.1.4.3. Preliminary considerations before connection, regarding the bat-
teries and their protections.
•
SPS AdvAnCe R and T devices incorporate the batteries in
the same box as the device, except for SPS AdvAnCe T b1
devices.
The UPS’s battery protection is internal by means of fuses
and is therefore not accessible to the user.
•
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 Tab. 3.
•
Inside the battery module, there are hAZARdoUS voLTAgeS
with risk of electric shock, so it is classified as a ReSTRICTed
ACCeSS AReA.
•
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 connectors.
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 re-
lated 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 bet-
ween modules, or to install an optional card in the slot, it is
necessary to remove its respective metal protective cover
screwed to the UPS. Remove the screws and cover.
5.2.1. Connection of the input.
•
As the device has Class I protection against electric
shock, it is obligatory and essential for the AC input
socket to have the earth conductor (
) installed. Check
that this is the case before continuing.
•
Take the device’s power cable, plug the female IeC con-
nector into the UPS and the Schuko plug at the other end of
the cable into an AC power socket.
5.2.2. Connection of the ieC output connectors.
•
All UPSs have “n” variable IeC output connectors according
to the model of the device.
•
Loads can be connected to all of the IeC connectors
provided that the rated power of the device is not
exceeded, otherwise untimely cuts will occur in the po-
wering of the loads connected to them.
•
If, in addition to the more sensitive loads, it is necessary
to connect high-consumption inductive loads, such as for
laser printers or CRT monitors, the starting up of these pe-
ripherals will need to be taken into account to prevent the
device from crashing.
we do not recommend connecting loads of this type due to
the amount of power they absorb from the UPS.
5.2.3. output terminals (only in sps advanCe T 3 kva models).
•
As the device has Class I protection against electric
shock, it is obligatory and essential to connect the
earth conductor (
) to each group of input terminals.
Check that this is the case before continuing.
•
The cross section of the input cables must be appropriate
for the current of the device, in compliance with local and/
or national Low-voltage electrotechnical Regulations.
•
Connect the output cables, respecting the order of the phase,
neutral and earth connection indicated on the labelling.
5.2.4. Connection to the optional battery module (backup exten-
sion).
•
failure to comply with the instructions in this
section and Safety Instructions EK266*08 car-
ries a high risk of electric shock and even death.
•
SPS AdvAnCe R and T devices incorporate the batteries
in the same box as the device, except for SPS AdvAnCe
T b1 devices.
•
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 Tab. 3.
