5.2. CONNECTION.
• This equipment is suitable to be installed in mains with
power distribution system of TT, TN-S, TN-C or IT, taking
into account when installing the particularities of the used
system and the national electrical regulation of the destination
country.
• For any information regarding the connection terminals of the
equipment, check table 2.
5.2.1. Connection to mains, terminals (X1 to X4).
• 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.
• Equipments without static Bypass line, in accordance with the
safety standard EN-IEC 62040-1, installation has to be provided
with a «Backfeed protection» system, as for example a con-
tactor, which will prevent the appearance of dangerous voltage
or energy in the UPS input mains during a mains fault.
The standard is applicable both if power supply is single phase or
three phase and for single units, and for each UPS of the parallel
system.
• 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, as well as the features
of the own «Backfeed protection».
•
There can be no derivation in the line that goes from the
«Backfeed protection» to the UPS, as the safety standard
would be infringed.
• Warning labels should be placed on all primary power switches
installed in locations away from the equipment to alert the elec-
trical maintenance staff of the presence of a UPS in the circuit.
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 input cables to the respective terminals according
to the available equipment setting.

)). Connect this conductor to terminal
For parallel systems, it will be necessary to repeat the connec-
tions that go from panel board to each equipment.
Connection to three phase mains:
Connect the power supply cables R-S-T-N to the input terminals
(X1), (X2), (X3) and (X4), 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 mains:
Connect the power supply cables R-N to the input terminals (X1)
and (X4), respecting the order of phase and neutral indi-
cated 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.
