The label will bear the following or an equivalent text:
Before working on this circuit.
ˆ Isolate the Uninterruptible Power System (UPS).
ˆ Check the voltage between all terminals, including the
protective earth.
Risk of UPS backfeed voltage.
• Connect the bypass input cables to the respective terminals ac-
cording to the available equipment setting.
For parallel systems, it will be needed to repeat the connections
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 terminals
(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 elec-
trical shocks, it is essential to install the protection earth con-
ductor (connect earth (
(X5), before supplying voltage to the input terminals.
• The «Recommended installation» information for each input
and output setting is available with the supplied documenta-
tion, 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.
ˆ For longer lengths correct the cross sections accordingly, in
order to avoid dropping voltages, by respecting the Regulations
or norms corresponding to the country.
ˆ In the own documentation and for each setting, it is available
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 connections
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),

)). Connect this conductor to terminal
(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), re-
specting 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 elec-
trical shocks, it is essential to install the protection earth con-
ductor (connect earth ( )). Connect this conductor to terminal
(X5), before supplying voltage to the input terminals.
• The original type of the battery circuit, preset from factory is
opened.

• 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 colour
of the cables (red for positive, black for negative, blue for middle
tap (N) and green-yellow for earth bonding), see Fig. 33.
• For extended back up times with more than one battery module
or cabinet, the connection will always be done in parallel among
them and the equipment.
