5.1.5. Transport to location.
Although the weight of the equipments is not so high, it is rec-
•
ommended to move the UPS by the use of a forklift, pallet truck
or by means of the most suitable means of transport by evalu-
ating the remoteness of the location point.
If the distance is high, it is recommended to move the equipment
still packaged till the installation place and unpack it later.
5.1.6. Preliminary considerations, before connecting the
equipment.
Check that the data in the nameplate are the required by the
•
installation.
A wrong connection or manoeuvring, can make faults in the UPS
•
and/or loads connected to itself. Read carefully the instructions of
this manual and follow the stated steps in the established order.
All the equipments have power cord with plug to be connected
•
to the AC mains.
In the same way, "N" output outlets or IEC connectors de-
pending on the model are supplied, for its connection with the
loads [output].
For the rest of connections is used an connector for the battery
connection [B1 version] and ports for communications.
Cross cable section of the input and output lines, will be calculated
•
from the currents stated in the nameplate of each equipment, and
respecting the Local and/or National Low Voltage Electrotechnical
Regulations.
Protections of the switchgear panel, will have the following fea-
•
tures:
For input line, type B for RCD devices and C characteristic
ˆ
for circuit breakers.
For the output (load feeding), C characteristic for circuit breaker.
ˆ
Regarding the size, they will be as minimum to the currents
stated in the nameplate of each UPS.
In the nameplate of the equipment there are only printed the
•
nominal currents as it is stated in the safety standard EN-IEC
62040-1. To calculate the input current, the power factor and the
efficiency of the equipment have been considered.
Overload conditions are considered as nonpermanent and ex-
ceptional operating mode.
If it is added peripherals to the input or output like transformers
•
or autotransformers to the UPS, the currents stated in the own
nameplates of those elements has to be considered in order to
use the suitable cross sections, by respecting the Local and/or
National Low Voltage Regulation.
When an equipment incorporates a galvanic isolation
•
transformer, as standard, as an option or either installed
by yourself, either at the UPS input line, output or in both, pro-
tections against indirect contact has to be fitted in (residual cur-
rent device) at the output of each transformer, because due to its
specification of isolation it will prevent the triggering of the
protections fitted in the primary of the transformer in case of
electrical shock in the secondary (output of the isolation trans-
former)
Remind you that all external isolation transformers already in-
•
stalled or supplied from factory, has the neutral of the secondary
connected to earth by means of a cable bridge between both
terminals. If it were required an isolated output neutral, remove
this cable bridge, keeping the precautions stated in the respec-
tive local and/or national low voltage regulations.
USER'S MANUAL
All standard UPSs have batteries in the same enclosure of the
•
equipment , less those ones as B1. In the first ones, the battery
protection is by internal fuses and there is no access to the end-
user.
Also the battery modules have internal protections by fuses and
in the same way as it is done in the own equipments, they are
not accessible by the end-user.
IMPORTANT FOR SAFETY: In case of installing the bat-
•
teries by yourself, the accumulators have to be provided
with a two pole circuit breaker protection sized to the features
stated in Tab. 2.
5.2. CONNECTION.
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 Reg-
ulations or norms of the corresponding country.
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 ex-
ceptional operating mode, so these currents will not be kept in
mind when sizing the protections.
To insert the option cards, it is needed to remove the fixing
•
screws of the smart slot and the own cover.
5.2.1. Connection of input.
Toke the input power cord with plug and IEC connector.
•
Insert the IEC connector to the UPS inlet.
•
Insert the plug in to the wall AC outlet.
•
5.2.2. Connection to output.
All the equipments have «N» output outlets or IEC connectors
•
depending on the model.
Connect the loads to the outlets or IEC connectors.
•
The 3 kVA B1 models with IEC output connectors also feature
•
output terminals. To access them, it is necessary to remove the
corresponding terminal protection cover, which will be replaced at
the end of the connection tasks.
Connect the loads to the output terminals, observing the order
of the phase, the neutral and the earth cable indicated on
the labelling of the device, otherwise faults and/or defects may
occur in the UPS and/or load or connected loads.
The sum of the loads connected to the different sockets,
IEC connectors and/or terminals must not under any cir-
cumstances exceed the rated power of the device.
If besides of the critical loads, it is required to connect lagging
•
loads of high consumption, like laser printers or CRT monitors,
the inrush currents of these peripherals will be kept in mind in
order to avoid blocking the equipment under the worst condi-
tions.
It is better to not connect the loads of this kind, due to the high
quantity of energy resources that take from the UPS.
