The label will bear the following or an equivalent text:
Before working on this circuit.
Isolate the Uninterruptible Power System (UPS).
Check the voltage between all terminals, in-
cluding the protective earth.
Risk of UPS backfeed voltage.
Connect the bypass input cables to the respective terminals
•
according to the available equipment setting.
For parallel systems, it will be needed to repeat the connec-
tions that go from panel board to each equipment.
Connection to three phase bypass mains:
Connect the power supply cables R-S-T-N to the bypass termi-
nals (X14), (X15), (X16) and (X17), respecting the phase
rotation and neutral indicated on the label of the equipment
and in this manual. If the phase rotation is not respected, the
equipment will not operate.
In case of discrepancies between the labelling and the instruc-
tions of this manual, the label will always prevail.
Connection to single phase bypass mains:
Connect the power supply cables R-N to the bypass ter-
minals (X14) and (X17), respecting the order of phase
and neutral indicated on the label of the equipment and
in this manual. If the order of the phase and neutral is not
respected, the equipment will be damaged seriously.
In case of discrepancies between the labelling and the instruc-
tions of this manual, the label will always prevail.
5.2.3. Connection to the output, terminals (X6 to
X9).
As this is an equipment with class I protection against
•
electrical shocks, it is essential to install the protection
earth conductor (connect earth (
terminal (X5), before supplying voltage to the input terminals.
The «Recommended installation» information for each
•
input and output setting is available with the supplied
documentation, manual and/or CD/Pendrive. In that information
is shown the circuit diagram, as well as the protection size and
minimum cross section of the wires that are connected to the
equipment, taking into account the nominal operating voltage.
All figures are calculated for a maximum total cable length
of 30 m between the distribution panel board, equipment and
loads.
For longer lengths correct the cross sections accordingly,
in order to avoid dropping voltages, by respecting the
Regulations or norms corresponding to the country.
In the own documentation and for each setting, it is avail-
able the information for «N» units in parallel.
Connect the output cables to the respective terminals ac-
•
cording to the available equipment setting.
For parallel systems, it will be needed to repeat the connec-
tions that go from panel board to each equipment.
Connection to three phase output:

Connect the loads to U-V-W-N output terminals (X6), (X7),
(X8) and (X9), respecting the phase rotation and neutral
indicated on the label of the equipment and in this manual. If
the phase rotation is not respected, the equipment will not
operate.
In case of discrepancies between the labelling and the instruc-
tions of this manual, the label will always prevail.
Connection to single phase output:
Connect the loads to U-N output terminals (X6) and (X9),
respecting the order of phase and neutral indicated on
the label of the equipment and in this manual. If the order of
the phase and neutral is not respected, the equipment will be
damaged seriously.
In case of discrepancies between the labelling and the instruc-
tions of this manual, the label will always prevail.
With respect to the protection that must be placed on the output
•
of the switchgear or manual bypass panel board, we recommend
that the output power should be distributed in at least four lines.
Each one should have a circuit breaker protection switch of the
suitable value. This type of output power distribution will allow,
in the event of a breakdown in any of the machines connected to
the equipment that causes a short-circuit, will only affect to the
line that is faulty. The rest of the connected loads will have their
continuity assured due to the tripping of the protection of the line
affected by the short-circuit only.
5.2.4. Connection to the battery terminals of the
equipment (X11, X12 and X23), with the
battery modules (X47, X48 and X49).
As this is an equipment with class I protection against
•
electrical shocks, it is essential to install the protection
earth conductor (connect earth (
terminal (X5), before supplying voltage to the input terminals.
The original type of the battery circuit, preset from factory is

Put the fuses in the corresponding fuse holder switch and
turn it «On» when it is indicated only, never before. To op-
erate in other way, can cause irreversible damages to the
equipment or serious and/or very serious injuries to the
fitter, as he has been exposed to a possible electrical dis-
charge during the connection of the UPS with the battery set
or battery cabinet.
Do manoeuvre the battery fuse holder switch and/or
•
switch, when the equipment is turned on. This mecha-
nisms cannot be turned on/off with load.
The connection of the battery cabinet with a UPS with power
•
rate higher than 20 kVA (LV) / 40 kVA (HV) or for B1 models,
will be done with the supplied cable bundle, by connecting
one side to terminals (X11), (X23), (X12) and (X19) of UPS
and the other one to terminals (X47), (X49), (X48) and (X10)
of battery module, always respecting the stated polarity on
the labelling of each element and this manual, as well as the
