4. Installation.
•
Check the Safety instructions, from section 1.2.3.
•
Check that the data in the nameplate are the required by the
installation.
•
A wrong connection or manoeuvring, can make faults in the
UPS and/or loads connected to itself. Read carefully the in-
structions of this manual and follow the stated steps in the
established order.
•
This UPS has to be installed by qualified staff and it
can be used by personnel with no specific training,
just with the help of this «Manual» only.
•
All connections of the equipment including the control
(interface, remote panel, ...), will be done with the
switches at rest and no voltage present (UPS power supply
switch to «Off»).
•
Never forget that the UPS is an electrical energy gener-
ator, so the user has to take the needed cautions against
direct and indirect contacts.
•
When there is only one equipment, omit all the instructions
and their implicit connections as regards to parallel systems.
•
Parallel system installation needs a switchgear panel with
input, output and static bypass single protections (the last
one for
TWIN/3 PRO
models higher than 10 kVA only), and a
manual bypass too.
This switchgear panel allows isolating only one equipment
from the system, when facing any malfunctioning and sup-
plying the loads with the rest of equipments during the pre-
ventive maintenance or during the reparation of itself.
Under request a manual bypass panel can be supplied for a
single equipment or a particular system.
•
In parallel systems, the length and cross section of the
cables that go from the switchgear panel till one of the
UPSs and vice versa, will be the same for all of them without
any exception.
•
Battery circuit is not isolated from input voltage. Haz-
ardous voltages can be found out between the battery
terminals and earth. Check that there is not input voltage be-
fore doing any intervention on them.
4.1. To be considered in the installation.
•
All the equipments and battery sets have terminals as con-
nection parts for power and connectors for communications.
•
Terminals for separate bypass line are only available in
TWIN/3
PRO
models higher than 10 kVA.
•
Cross cable section of the input and output lines, will be cal-
culated from the currents stated in the nameplate of each
equipment, and respecting the Local and/or National Low
Voltage Electrotechnical Regulations.
For the bypass current stated in the nameplate, has to be
considered two groups of equipments:
Equipments up to 10 kVA
TWIN/3 PRO
. Current on
phase R is higher to the other two, because the input of
the UPS is common with the bypass line.
Equipments > 10 kVA
TWIN/3 PRO
. These equipments
have separate terminals for UPS input and bypass line.
•
Protections of the switchgear panel, will have the following
features:
For input and bypass lines, type B for RCD devices and
C characteristic for circuit breakers.
For the output (load feeding), C characteristic for circuit
breaker.
Regarding the size, they will be as minimum to the cur-
rents stated in the nameplate of each UPS. Pay attention to
the UPSs up to 10 kVA and three phase input, because a
four pole switch has to be fitted in as input protection and a
second one of two poles between this one and the own UPS,
in order to protect the phase R and neutral.
•
In the nameplate of the equipment there are only printed the
nominal currents as it is stated in the safety standard EN-IEC
62040-1. To calculate the input current, the power factor and
the efficiency of the equipment have been considered.
Overload conditions are considered as nonpermanent and
exceptional operating mode.
•
If it is added peripherals to the input, output or bypass like trans-
formers or autotransformers to the UPS, the currents stated in
the own nameplates of those elements has to be considered
in order to use the suitable cross sections, by respecting the
Local and/or National Low Voltage Regulation
•
When an equipment incorporates a galvanic isolation
transformer, as standard, as an option or either in-
stalled by yourself, either at the UPS input, bypass line,
output or at all of them, protections against indirect contact
has to be fitted in (residual current device) at the output of
each transformer, because due to its specification of isolation
it will prevent the triggering of the protections fitted in the pri-
mary of the transformer in case of electrical shock in the sec-
ondary (output of the isolation transformer)
•
Remind you that all external isolation transformers already
installed or supplied from factory, has the neutral of the sec-
ondary connected to earth by means of a cable bridge be-
tween both terminals. If it were required an isolated output
neutral, remove this cable bridge, keeping the precautions
stated in the respective local and/or national low voltage reg-
ulations.
•
All standard UPSs have batteries in the same enclosure of
the equipment , less those ones as B0 and B1. In the first
ones, the battery protection is by internal fuses and there is
no access to the end-user.
Accumulator cabinet or modules have battery protection
too, and in this case, they are duplicated. An internal ones
through fuses with no access for the end-user and an addi-
tional ones by means of a two pole circuit breaker.
•
IMPORTANT FOR SAFETY: In case of installing the
batteries by yourself, the accumulators have to be pro-
vided with a two pole circuit breaker protection sized to the
features stated in table 2.
4.2. Reception of the equipment.
4.2.1. Unpacking, content checking and
inspection.
•
To unpacking, see section 4.2.3.
•
On receiving the device, make sure that it has not suffered
any damage in transport (impact, drop, ...) and its features
correspond with the ones in the order, so it is recommended
to unpack the UPS and make a first visual inspection.
