the rectifier cabinet.
Fig. 22. Connection of the battery cabinet to the system.
• Connect the cable bundle, in general it is supplied, between
the terminals (X11) - (X12) of the system and (X47) - (X48)
of the battery or rack cabinet, by respecting the colour of the
cables (red for (+), black for (–) and green-yellow for the earth
bonding ( )) as week as the polarity stated in the labelling
of the equipment (see Fig. 22).
•
In those systems with more than one battery cabinet/
rack, keep in mind to connect them in parallel and with
the own system too, depending on each particular case. In
any case, the supplied battery circuit diagram with the docu-
mentation will always prevail.
7.6. Connection to AC mains.
Terminals (X1), (X2), (X3) and (X4).
•
All protections or switches of the system has to be in «Off»
position, and in particular the one belonging to batteries in
the equipment (F/Q3) and its homologous (F/Q8) in the
battery cabinet, in case there were an external battery set.
As the fuses are supplied inserted in the fuse holder,
to avoid misleading and losses, it is important to check
that the switches are opened (Off).
• It is mandatory to earth the equipment (
the main protective earth terminal or rod (X5), making
sure that it is done before turning on the input voltage of the
equipment.
• Connect the power supply cables to terminals (X1) and (X4)
for single phase equipments or (X1), (X2), (X3) and (X4)
for three phase equipments, by respecting the phase and
neutral rotation, stated in the labelling of the DC Power-S.
7.7. Connection of the loads.
• It is mandatory to earth the equipment (
the main protective earth terminal or rod (X5), making
sure that it is done before turning on the input voltage of the
equipment.
• DC Power-S can be supplied from factory with the positive
pole connected to earth, negative to earth or floating. In the
nameplate and in the terminal labelling, it is identified the con-
nection type by means of the sign «+» or «–», written down
before the output voltage figure, which will indicate the alive
pole.
By default and if it is not stated, all the equipments
are supplied with floating output voltage.
It is very important to assure that the loads that are
being connected to the equipment have the same
type of connection of itself, otherwise it will mean a risk for the
personnel and the destruction of the installation and annexes
equipments.

The typology of the output protection is determined and es-
tablished as follows:
ˆ Floating output, two poles protection.
ˆ Positive pole connected to earth, single pole protection in
the negative pole.
ˆ Negative pole connected to earth, single pole protection
in the positive pole.
The typology of the output protection is applicable to the bat-
tery switch or protection and to any protection of the DC out-
going distribution.
7.7.1. No DC outgoing distribution.
Terminals (X6) and (X9).
7.7.1.1. Floating output.
• All protections or switches of the system has to be in «Off»
position, and in particular the one belonging to batteries in
the equipment (F/Q3) and its homologous (F/Q8) in the
battery cabinet, in case there were an external battery set.
• Connect the loads or busbar to the output terminals (X6) and
(X9), by respecting the colour of the cables (red for positive
and black for negative) and the polarity stated in the labelling
of the equipment.
• Connect the earth of load or loads to the earth terminal or
rod (X5).
•
It is recommended to distribute the output in several lines with
two poles type protection elements each one (fuse switches
or circuit breakers), to be installed by the client.
7.7.1.2. Output with the positive earthed.
• All protections or switches of the system has to be in «Off»
position, and in particular the one belonging to batteries in
the equipment (F/Q3) and its homologous (F/Q8) in the
battery cabinet, in case there were an external battery set.
• Connect the loads or busbar to the output terminals (X6) and
(X9), by respecting the colour of the cables (red for positive
and black for negative) and the polarity stated in the labelling
of the equipment.
• Connect the earth of load or loads to the earth terminal or
rod (X5).
• It is recommended to distribute the output in several lines with
single pole type protections elements each one in the nega-
tive pole (fuse switches or circuit breakers), to be installed by
the client.
7.7.1.3. Output with the negative earthed.
• All protections or switches of the system has to be in «Off»
position, and in particular the one belonging to batteries in
the equipment (F/Q3) and its homologous (F/Q8) in the
battery cabinet, in case there were an external battery set.
• Connect the loads or busbar to the output terminals (X6) and
(X9), by respecting the colour of the cables (red for positive
and black for negative) and the polarity stated in the labelling
of the equipment.
• Connect the earth of load or loads to the earth terminal or
rod (X5).
• It is recommended to distribute the output in several lines with
single pole type protections elements each one in the posi-
tive pole (fuse switches or circuit breakers), to be installed
by the client.
