2.2. ADDITIONAL SAFETY NOTICES.
•In the point of view of the installation and electrical safety,
bypass panels must be considered as transformers or
power lines of distribution.
•As the equipment has protection against electrical shock of
class I, it is essential to install the protective earth cable (con-
nect the PE cable to the terminal ( )).
•The bypass panel must be installed by qualified per-
sonnel and it can be used by trained personnel
only, just with help of this «User’s manual».
•It is important to meet the safety instructions stated in the
own «User’s, installation and start manual of the UPS».
The instructions that you are reading are referred to the
own manual bypass panel only, and they are complemen-
tary to the «UPS user’s manual».
•The neutral regimes from the input to the output are iden-
tical for the bypass panels «with no galvanic isolation». It is
mandatory to keep the neutral regime the same, for both the
bypass panel and the UPS.
•When a bypass panel has a galvanic isolation trans-
former, as an option and fitted in by the factory or in-
stalled later on by the end user, either in the input or output of
the equipment, protections against indirect contact (RCD) must
be fitted in at the output of each isolation transformer, in order
to avoid the electrical shock risk in the secondary winding
(transformer output), because due to its own nature of iso-
lating will avoid the tripping of the protections fitted in the
primary winding of the transformer.
•As a reminder, all the installed isolation transformers or
those ones supplied from factory, the output neutral (N) is
connected to the PE ( ) through a cable bridge between
the neutral and PE terminals (TT regime). In case, it is re-
quired an isolated output neutral, this cable bridge must be
removed (IT regime), take all the cautions stated in the re-
spective local and/or national low voltage regulations.
•In those installations with IT neutral regime, the switches
and circuit breaker protections must break the NEUTRAL
apart from the three phases.

4. DESCRIPTION.
•The manual bypass is a peripheral option to the UPS, which
allows selecting the power supply source that feeds the
loads, either from the UPS or directly from commercial elec-
trical mains. If the UPS has an isolation transformer at its
output or in the static bypass line, the manual bypass panel
must incorporate it, in order to make euqal both neutral re-
gimes.
The isolation transformer is an option, which provides gal-
vanic isolation between the primary and secondary wind-
ings, in such way that it attenuates the electrical noises
and transients coming from mains largely, and also they are
transferred to the secondary winding in minor extent.
•The type of the manual bypass panel is make before break,
so it doesn’t break the power supply to the loads when
doing the shifting, unless it is operated in different order of
the established one.
•In case the panel incorporates the «Backfeed protection»
contactor, its operating must be considered as automatic
and it doesn’t require any attention unless any of the pro-
tection fuses is blown. Do not handle the fuse holder switch
of the «Backfeed protection», unless it is needed to replace
any of these protection parts.
•These instructions are generic for each one of the stated
series in the nomenclature, regardless of the type of panel.
Omit those terminal connections and manoeuvring of the
switches that your unit doesn’t have.
4.1. TYPES OF MANUAL BYPASS PANELS.
•Structurally, there are two type of manual bypass panels
according to the own structure of the UPS:
Standard or basic (Fig. 1). With common input for the
UPS feeding (rectifier-PFC) and the static bypass line.

it makes possible to supply both mains from uneven
sources, like: two companies, one company and one
generator set, etc...

•The auxiliary contacts of the manual bypass and output
switches, are not available in all series.
•For parallel or redundant systems based on «n» UPS’s, the
quantity of switches in the panel will be doubled for each one
of them that it is included, less the own manual bypass switch
that it is always common for the complete parallel system.
•In graphical way, Fig. 2 and 3 the galvanic isolation trans-
former is shown at the output, less those ones which under
request or particular specifications are requested. In the
point of view of taking advantages of the inherent features,
efficiency and price, it is the most recommended electrical
connection.
Nevertheless and depending if the unit has or not separate by-
pass line, the isolation transformer can be placed in one side or
other:
The standard or basic equipment and in case it is used
as input voltage adaptor. So its electrical position will
be at the input necessarily.
Those models with separate bypass line, it will be con-
nected at its input, when input mains of the UPS and
the static bypass line come from two different sources;
in order to avoid the direct connection of the neutral at
the output of the own UPS.
•The manual bypass panel will be connected with the input line,
static bypass line, the UPS and loads, by respecting the
phase or phases rotation, neutral N and the PE cable
stated in the labelling of any of them.
•If case of any discrepancy between the labelling and the in-
structions of this manual, the labelling will always prevail.

5. INSTALLATION.
•Read and respect any information as regards to Safety,
which is described in section 2 of this document. To ob-
viate any of the described indications, can cause serious or very
serious injuries to persons with direct contact or accidents in the
vicinity, as well as failures in the own bypass panel, equipment or
equipments and/or loads connected to the system.
•Check that the data in the nameplate is the required one by
the installation.
•A wrong connection or manoeuvring, can cause failures in
the panel, equipment or equipments and/or loads connected
to the system. Read the instructions of this manual carefully
and follow the stated steps in the established order.
•The connection will only be done, if the switches of
the equipment or equipments are in off position and
with no mains (switch or switches of the power supply line
or lines of the panel must be turned «Off»).
•Any connection of the bypass panel described in this docu-
ment will be done according to both the labelling of the
unit and the single line diagrams. Structurally, there are six
types of panels, regardless of their possible configurations
(L, M, N,...):
Generic manual bypass panel for a standard UPS (Fig. 3).
Generic manual bypass panel for a standard UPS with
separate bypass line (Fig. 4).
Manual bypass panel for «n» standard parallel or re-
dundant UPS’s (Fig. 5). For UPS of CUBE3+, TWIN PRO and
TWIN PRO 33 series.
Manual bypass panel for «n» standard parallel or redun-
dant UPS’s (Fig. 6), for UPS of ADAPT and X-TRA series.
Manual bypass panel for «n» parallel or redundant UPS’s
with separate bypass line (Fig. 7), for UPS of CUBE3+,
TWIN PRO and TWIN PRO 33 series.
Manual bypass panel for «n» parallel or redundant UPS’s
with separate bypass line (Fig. 8), for UPS of ADAPT and
X-TRA series.
Apart from the stated structures, there are several aspects re-
garding the connection of the control wiring of each UPS series,
which are explained later on in this section.
•The reproduced illustrations in this document are mere
examples, and they are intended to show the lineal order
layout of the manoeuvring mechanisms, without taking ac-
count of the physical format of them due to the power rate
of the equipment. Another factor to consider, it is that all
figures show the circuit breaker switch option “P” of the
manoeuvring mechanisms.
•According to the model of the panel, the enclosure can differ
(plastic, metallic case or metallic cabinet), so the aspect of
them could be affected, but the order would be the same.
•Depending on the power of the bypass panel and requested
version, the manoeuvring mechanisms can differ in quantity
(parallel systems), quantity of poles (depending on the configura-
tion), format, size and type (switch or circuit breaker), but they
will always be identified through the labelling.
Pay attention to the stated steps to change the oper-
ating mode, attending the labelling over the manoeu-
vring mechanisms.
•The manual bypass panel version with separate bypass line (-B),
has additional parts of connection and control, which can only
be found in this type of panel. Omit, any reference to them in the
standard or basic version.
5.1. TO CONSIDER IN THE INSTALLATION.
•These instructions are generic for any manual bypass panel
of this series. Omit those not available terminal connections.
•All connections in the panel are done through terminals.
Nevertheless in some models and due to their high power or
current, the connection of the cables can be done directly to
the copper rods of the own switches.
•Regarding the main PE cable and earth bonding cable con-
nections, the panels usually have two points located on op-
posite ends, generally by threaded stud.
•In the documentation supplied in the CD-ROM to-
gether with each UPS, it is available the information
regarding the «Recommended installation» for each one of
the input and output configurations. In this document, it is
shown the circuit diagrams, the size of the protections and
minimum cross cable section of the cables that join the
equipment with the panel according to the nominal oper-
ating voltage. All figures are calculated for a maximum
cable length of 30 m between the distribution panel,
equipment and loads.
For higher lengths correct the cross cable sections in
order to avoid dropping voltages, by respecting the
Regulations or Standards corresponding to the country.
In the same documentation and for each configuration, it
is available the information for «N» units in parallel, as
well as the features of the own «Backfeed protection».
It is mandatory to respect all the indications stated in
the UPS user’s manual as regards to the «Backfeed pro-
tection», considering the possibility of having or not the
separate bypass line and the corresponding actions to
make in each case.
•In parallel systems, the length and cross cable sec-
tion, which goes from the panel till each UPS and vice
versa, will be the same for all of them with no exception.
•Cross cable section must be always considered according
to the size of the own terminals of the switches, in order
to clamp them properly and to give an optimal contact be-
tween both parts.
USER'S MANUAL

10 SALICRU
•The data in the nameplate of the equipment shows the
nominal currents only as the safety standard EN-IEC
62040-1 states. The overload conditions are considered as
a nonpermanent and exceptional operating mode.
•If peripheral elements are going to be added at the input, output
or bypass of the UPS or parallel systems like transformers or auto-
transformers, the stated currents in the nameplates of those parts
must be considered in order to use the appropriate cross cable
section, by respecting the Local and/or National Low Voltage Elec-
trotechnical Regulation.
•Once the installation is finished, do not forget that the by-
pass panel is connected to a UPS or UPS set. Starting from
the concept that the UPS is an electrical generator, the end
user will take the needed cautions against the direct or in-
direct contact.
5.2. EQUIPMENT RECEPTION.
5.2.1. Unpacking, contents checking and inspection.
•To unpack it, see section 5.2.3.
•When receiving the equipment, check that no damages
have occurred during transport (impacts, falls, ...) and the

•When discrepancies between the labelling of the
equipment and the instructions of this user’s manual
exist, the labelling in the equipment will always prevail.
•The references in bold between brackets, which are shown
in the different points of this section, correspond to the UPS
elements identified in their own user’s manual. For more infor-
mation consult that document.
5.3.1. Connection of the power supply to the bypass panel.
UPS input line (rectifier).
•It is mandatory to connect the main protection earth
cable to the terminal labelled as ( ), being sure that
it is done before supplying voltage to the bypass panel.
•Connect the power supply cables of the input line to tto the termi-
nals labelled as «INPUT LINE» of the bypass panel, by respecting
the phase (R) or phases (R-S-T) and neutral (N) rotation, stated in
the equipment labelling and this manual.
It is essential to have neutral (N).
5.3.2. Connection of the power supply of the bypass panel.
Static bypass line (type of panels -B only).
•It is mandatory to connect the main protection earth
cable to the terminal labelled as ( ), being sure that
it is done before supplying voltage to the bypass panel.
•Connect the power supply cables of the bypass line to the by-
pass panel, to the terminals labelled as «STATIC BYPASS INPUT
LINE», by respecting the phase (R) or phases (R-S-T) and neutral
(N) rotation, stated in the equipment labelling and this manual.
It is essential to have neutral (N).
5.3.3. Connecting the UPS with the bypass panel.
•Connect a cable bundle between the terminal strip of the
bypass panel labelled as «UPS INPUT» and the UPS input
terminals labelled as «INPUT», by respecting the phase (R) or
phases (R-S-T) and neutral (N) rotation, stated in the equipment
labelling and this manual.
•Those equipments with separate static bypass line, connect
a cable bundle between the terminal strip of the bypass
panel labelled as «STATIC BYPASS INPUT» and the UPS
input terminals labelled as «STATIC BYPASS», by respecting
the phase (R) or phases (R-S-T) and neutral (N) rotation, stated in
the equipment labelling and this manual.
•Connect the cable bundle between the terminal strip of
the bypass panel labelled as «UPS OUTPUT» and the UPS
output terminals labelled as «OUTPUT», by respecting the
phase (R) or phases (R-S-T) and neutral (N) rotation, stated in the
equipment labelling and this manual.
5.3.4. Connection of the loads to the bypass panel.
•It is mandatory to connect the main protection earth
cable to the terminal labelled as ( ), being sure that
it is done before supplying voltage to the bypass panel.
•Connect the loads to the terminal strip of the bypass panel
labelled as «LOADS OUTPUT», by respecting the phase (R) or

•By means of control wiring (minimum 1 mm2and
maximum 2,5 mm2 ), it is mandatory to connect the
terminal strip labelled as «BYPASS AUXILIARY CONTACT» of
the UPS with the ones in the bypass panel. These signal ter-
minals are the extension of the normally opened auxiliary
contact, of its respective internal manual bypass.
The UPS auxiliary terminals are labelled as follows, de-
pending on the product series:
ADAPT, pins 1 and 2 of (JP5).
CUBE3+, two terminal strip (X51).
X-TRA, terminals (MBY1) and (MBY2).
•This connection is a safety lock against wrong manoeuvring,
which otherwise would involve damages in the UPS and/or
supplied loads, because it switches the inverter «Off» when
turning any of the manual bypass switches «On».
5.3.6. Connection of the auxiliary contact of the UPS output
switch, with the bypass panel (available in CUBE3+
series only).
•The UPS output switch has a normally opened auxiliary con-

5.3.7.1. Power connections.
•Make the connections stated in sections 5.3.1 and 5.3.2.
•Make and repeat for each equipment that makes the
system, the connections stated in section 5.3.3.
5.3.7.2. Connection of the auxiliary contact of the manual bypass
switch of each UPS, with the one in the bypass panel (not
available in panels of TWIN PRO and PRO 33 series).
•By means of control wiring (minimum 1 mm2and
maximum 2,5 mm2 ), it is mandatory to connect the
terminal strip labelled as «BYPASS AUXILIARY CONTACT» of
the UPS with the ones in the bypass panel. These signal ter-
minals are the extension of the normally opened auxiliary
contact, of its respective internal manual bypass.

13
The UPS auxiliary terminals are labelled as follows, de-
pending on the product series:
ADAPT, pins 1 and 2 of (JP5).
CUBE3+, two terminal strip (X51).
X-TRA, terminals (MBY1) and (MBY2).
•The way of connecting the control cables of the UPS’s with
the panel will differ depending on the UPS series, as well
as the quantity of available terminals in the control strip:
CUBE3+.
Make the parallel connection among the auxiliary con-
tacts of the manual bypass switch of each equipment
and the ones in the bypass panel (see Fig. 5 and 7).
ADAPT and X-TRA.
The manual bypass switch of the panel will have as
many extended auxiliary contacts of the control strip
as quantity of UPS’s to connect in parallel (see Fig. 6
and 8).
Connect the terminal strip of the panel with each UPS
of the parallel system respectively. Never joint these
connections, because each UPS has internal different
grounds.
As it has been stated previously, this connection is a safety lock
against wrong manoeuvring.
5.3.7.3. Connection among the auxiliary contact of the output
switch of each UPS, with the ones in the bypass panel
(available in panels of CUBE3+ and X-TRA series).
•The output switch of each UPS has a normally opened
auxiliary contact , with a cable as a bridge mode (PT),
which closes the circuit in the terminal strip (X45) in
CUBE3+ series or in terminal strip (OAC-1) and (OAC-2)
in X-TRA series.
•Remove it and by means of control wiring (minimum 1 mm2
and maximum 2,5 mm2 ) connect the terminal strip labelled
as «OUTPUT AUXILIARY CONTACT» of the UPS (X45) or
(OAC-1) and (OAC-2) with the ones in the bypass panel,
keeping in mind the correlative order of each one of them.
So, the «OUTPUT AUXILIARY CONTACT» terminals (X45) or
(OAC-1) and (OAC-2) of UPS nr 1 to the auxiliary terminal
strip «OUTPUT 1 UPS», the terminals «OUTPUT AUXILIARY
CONTACT» (X45) or (OAC-1) and (OAC-2) of UPS nr 2 to
the auxiliary terminal strip «OUTPUT 2 UPS» and so on,
according to the quantity of equipments that makes the
system.

6. START UP AND SHUTDOWN.
•These instructions are generic for any manual bypass panel
of this series, parallel and redundant equipments included.
Omit those manoeuvring of the switches that your unit
doesn’t have.
•The references in bold between brackets, which are shown
in the different points of this section, correspond to the UPS
elements identified in their own user’s manual. For more infor-
mation consult that document.
•The shown illustrations in this section are mere examples and
they are with four poles switches of DIN rail type, but in practice
they can differ in one or more aspects like: type of panel configu-
ration, format, size or protection type. Nevertheless, in any case
the order will not be different from the stated in them.
Also, in the manual bypass panels in parallel or redundant
equipments, the illustrations do not match with any preset
system, so they are generic for any panel regardless of the
quantity of equipments in parallel or redundant that belong
to.
6.1. CONTROLS BEFORE THE START UP.
•Check that all connections have done properly, by re-
specting the labelling of the equipment and the instructions
in section «INSTALLATION». If phase or phases and neu-
tral rotation is not respected, important damages can be
caused to the panel, UPS or UPS’s and/or connected loads.
•In order to avoid bad electrical contacts, check the connec-
tions screws are firmly tighten.
•Check all switches coming from the power supply which
feeds the bypass panel, the own ones in the panel (see Fig.
9 or 10 depending on the case) and the ones in the UPS or
UPS’s are turned «Off».

•Make sure that all the loads are shutdown (start up
switches turned «Off»).
•Proceed in the established order of this document. Any
wrong manoeuvring over the stated switches of the by-
pass panel, or the ones in the UPS or UPS’s, can cause a break or
short-circuits in the power supply to the loads, with the unin-
tended and unexpected consequences for any part of the set.
•In the installation section, for single and parallel equipments,
it is stated the need of connecting the auxiliary contact of
the manual bypass with the one in the manual bypass panel.
Thanks to this auxiliary safety contact, in case of wrong or
different manoeuvring than the stated in this section, it is
avoided to overlap the inverter output with the UPS input
power supply.
For any change in the operating mode, respect the steps
stated in the instructions of this section strictly, and in par-
ticular ,those ones for TWIN PRO and TWIN PRO 33 series,
which do not have this auxiliary contact, but they have the
needed protections, in order to make the steps in the es-
tablished order.
Before starting the equipment up, check that the
manual bypass switch of the equipment or equip-
ments and the one in the manual bypass panel are in the
same position (UPS and Off or BYPASS and On).
6.2. OPERATION TO SHIFT FROM «OUT OF SERVICE»(UPS
OR UPS’S TO «OFF») TO «NORMAL OPERATING» (LOADS
SUPPLIED BY THE UPS OR UPS’S).
•Turn the external protections of the bypass panel «On» (RCD and/
or circuit breaker switches), they will supply energy to the termi-
nals labelled as «INPUT LINE».
•In panels with separate bypass line (-B), turn the external
protections of the bypass panel «On» (RCD and/or circuit breaker
switches) «On», they will supply energy to the terminals labelled
as «STATIC BYPASS INPUT LINE».
6.2.1. Manual bypass panel with one UPS only.
•Turn the «UPS INPUT» and «UPS OUTPUT» switches of the
bypass panel to «On». In case of including the separate by-
pass line (-B), turn the «STATIC BYPASS» switch of the bypass
panel «On» too. In the illustration of Fig. 11, it is shown the
position of switches once the manoeuvring has been done.

nals of the panel, through the UPS’s.
6.3. SHIFTING FROM «NORMAL OPERATING» (LOADS
SUPPLIED BY THE UPS OR UPS’S) TO «MAINTENANCE
OPERATING» (LOADS SUPPLIED THROUGH THE
MANUAL BYPASS).
6.3.1. Manual bypass panels with one UPS only.
•Put the UPS on bypass (inverter «Off»), according to the
procedure stated in the «User’s, installation and start up
manual» of the UPS.
It is essential to shutdown the inverter of the UPS
before proceeding, otherwise a short-circuit at its
output will be made with unexpected and unintended out-
comes for any part of the set (UPS, panel and loads).
•Remove the mechanical lock from the switch labelled as
«MANUAL BYPASS» in the bypass panel and turn it «On».
Keep the mechanical lock in a safe place, because it will
have to put it back, once the maintenance or fixing tasks
have been finished.
•Manual bypass panels with isolation transformer, the loads
will be supplied with a clean and/or attenuated voltage
from electrical noises.
•Turn «UPS INPUT» and «UPS OUTPUT» switches from bypass
panel to «Off». In case the separate bypass line (-B) was avail-
able, turn the «STATIC BYPASS» switch of the bypass panel to
«Off» too. In the illustration of Fig. 13, it is shown the position
of the switches once the manoeuvring has been finished.
•Loads are supplied by mains directly through the manual
bypass panel and UPS is completely shutdown, so it is
ready to be serviced for a preventive maintenance, fixing
or replacement for another equipment with the same speci-
fications.

•In case of faulty UPS, it can also be removed and sent to the
factory for its fixing. Nevertheless it is better not do it, because
loads would be connected to mains directly and so exposed to
mains fluctuations.
Even, if this alternative is going to be done, it is manda-
tory to remove any cable bundle connected to the
panel, which has at its opposite end the cables bare from
isolation, resulting in a risk of electrocution or short-circuit in
case of turning on any of the panel switches.

It is essential to shutdown the inverters of the
UPS’s before proceeding, otherwise a short-circuit at
its output will be made with unexpected and unintended out-
comes for any part of the set (UPS’s, panel and loads).
•Remove the mechanical lock from the switch labelled as
«MANUAL BYPASS» in the bypass panel and turn it «On».
Keep the mechanical lock in a safe place, because it will
have to put it back, once the maintenance or fixing tasks

are ready to be serviced for a preventive maintenance,
fixing or replacement for another equipment with the same
specifications.
•In case of faulty UPS, it can also be removed and sent to the
factory for its fixing. This option is valid when the power of the
equipments, which are still installed is enough to supply the
loads. Even it is unlikely but not impossible, any new fault in any
of the remaining equipments and the possible consequences
that could happen will be assumed.
Even, if this alternative is going to be done, it is man-
datory to remove any cable bundle connected to the
panel, which has at its opposite end the cables bare from
isolation, resulting in a risk of electrocution or short-circuit in
case of turning on any of the panel switches.
