Regarding the connections of the UPS with the battery
module in models of 8 and 10 kVA, make the following steps,
but reading section 4.3.4 previously (see figure 11):
Connect the supplied earth joint cable, between the UPS
and battery module.
To connect the battery module with the equipment, there
is a connector on the rear side of both units. Insert the
aerial connector from battery module into the connector
of the equipment.
Battery module has base connector, foreseen to connect
the aerial connector from another module.

4.3. Connection.
Ŗ
Cross cable section used in the power supply of the
equipment and loads to feed, will be sized according
to the nominal current stated in the nameplate sticked on the
equipment, by respecting the Low Voltage Electrotechnical
Regulations or norms of the corresponding country.
Ŗ
Installation will have the suitable input protections sized to
the current of the equipment and stated in the nameplate of
the equipment (residual current devices type B and circuit
breaker with C characteristic or any other equivalent one).
Overload conditions are considered as a nonpermanent an
exceptional operating mode, so these currents will not be
kept in mind when sizing the protections.
Ŗ
Output protection will be done with a circuit breaker of C char-
acteristic or any other equivalent one.
Ŗ
The equipments can be installed and used by per-
sonnel with not specific training, just with only help of
this «Manual», less those ones with power blocks have to be
installed by qualified personnel.
Ŗ
In the hardwired models, is needed to remove the fixing
screws of the protection cover and the own cover, to proceed
to the parallel connection.
Also the equipments from 4 to 10 kVA have cable glands in
the own cover, through them the cables can be conducted
and fixed.
When finalising the corresponding tasks, the cover will be in-
stalled and its fixing screws again.
Ŗ
To insert the option cards, it is needed to remove the fixing
screws of the smart slot and the own cover.
When finalising the corresponding tasks, the cover will be in-
stalled and its fixing screws again.
Ŗ
It is recommended to use terminals in all the cable ends,
which are connected to the power blocks, specially in the
power ones (input, output and bypass).
Ŗ
Check the correct torque in the screws of the power blocks.
4.3.1. Connection of input.
Ŗ
As this is a device with class I protection against elec-
tric shocks, it is essential to install a protective earth
conductor (connect earth(
)
). Connect the conductor to
the terminal, before connecting the power supply to the input
power block.
Ŗ
Equipments with IEC outlets (models from 0,7 to 2 kVA):
Take the power cord with schuko plug and IEC connector.
Connect the IEC connector to the UPS inlet.
Insert the schuko plug to the AC mains outlet.
Ŗ
In equipments with power blocks (3 kVA models).
Connect the power supply cables to input power blocks
R (L)
,
and
N
, by respecting the phase and neutral rotation
stated in
the labelling of the equipment and in this manual
. If this
rotation is not respected, serious faults could happen.
The main earth input protection is located between the
phase and neutral terminal. Pay special attention to
the correct connection.
When discrepancies exist between the labelling and the in-
structions of this manual, the labelling will always prevail.
Ŗ
For hardwired equipments (models from 4 to 10 kVA).
These equipments have separate power blocks for
the static bypass line. For installations with
only
one power supply, leave a cable as a bridge mode
"Jumper" between
the terminals
JP
and
L
(bypass
phase line).
Do not fit this "Jumper" bridge
, if the equipment is a
frequency converter (see figure 13).
In accordance with safety standard EN-IEC 62040-1,
the installation has to be provided with an automatic
«Backfeed protection» system, as for example a con-
tactor, which will prevent the appearance of voltage or
dangerous energy at the input line during a mains fault
(see figure 12 and respect the circuit diagram of the par-
ticular «Backfeed protection» for the equipment without
bypass line).
There can be no derivation in the line that goes
from the «Backfeed protection» to the UPS, as
the safety standard would be infringed.
It is not needed to install the
«Backfeed protection»,
in case the equipment is a frequency converter, because
the own operating principle of the equipment disables the
possibility of having bypass line.
Warning labels should be placed on all primary power
switches installed in places away from the device to alert
the electrical maintenance personnel of the presence of
a UPS in the circuit be infringed.
