5.2.9.3. Terminal strip, battery temperature probe (X34). For
batteries in a separate cabinet only.
• As the battery manufacturer recommends a variable floating
voltage depending on the ambient temperature.
The control of this feature will be done through the measure-
ment of the temperature by means of a probe, located inside
the cabinet itself when batteries and equipment are fitted in
the same enclosure.
For those cases that batteries are supplied in a separate cabinet
out from the own UPS (models >20 kVA (LV) / >40 kVA (HV) or
B1 equipments, there will be a terminal strip of two pins
(X34)
,
that allows bringing the probe located at the end of a two wires
bundle with 4.5 m., till inside the battery cabinet.
The connection of the two wires from the cable bundle to the
terminal strip
(X34)
does not have polarity.
• Also via this probe the ambient temperature inside the battery
cabinet can be visualized in the control panel with LCD.
• The bundle with the probe will always be supplied already con-
nected to the terminal strip
(X34)
, so it is only necessary to cut
the clamp that keep it rolled, to take it out from the UPS cabinet
and enter it into the battery cabinet, in both cases, through the
foreseen cable bushing
(PR)
.
5.2.10. Connection of parallel BUS (X36i) and (X36o).
• This section is only useful for parallel systems.
• For the correct operation of the parallel functions and operating,
any unit connected in parallel are continuously communicated
among them. It is achieved by means of the called communica-
tion line or BUS.
• Any operation of this section, regarding parallel systems, has to
be done by authorised staff of our firm.
• Once the power connections of the UPSs of the parallel systems
are done, it is needed to make the ones related to the control
or communication BUS. To do it, connect them in a sequential
way, two lines of the communication BUS between a unit and
its adjacent.
• Together with each UPS of a parallel system, it is supplied a 15
wires bundle with HDB15 connectors at both ends, one male
and the other one female, with a length of 5 m. Therefore, there
will be as many communication BUS bundles
(BC)
, as quantity
of equipments to parallel have the system.
See Fig. 6 to 14 for COM
port physical layout.

Connection of the communication BUS.
5.2.10.1. Connection of the communication or BUS bundle (BC).
• Respect the sequence and connection order of the communica-
tion BUS among correlative equipments.
Although the order of the connections of communication BUS
among equipments are made, is not important, on condition
that the communication loop is completed or closed properly, it
is advisable to carry out the connections with the immediately
next equipments in order simplify the connection.
• The connection limit of the installation, will be determined by
the quantity of available equipments to parallel and in any case
till a maximum of four units.
• Each equipment has two HDB15 connectors for the communi-
cations among them, one male labelled as “Output”
(X36
o
)
and
another one female as “Input”
(X36
i
)
.
• In the same way, all the bundles supplied with the equipments,
are equal in connections and length.
DO NOT MODIFY THE COMMUNICATION BUS
BUNDLE, OR THE CONNECTORS UNDER ANY
CONCEPT
.
• Take one of the bundles and insert the HDB15 female connector
located in one of its ends, into the male connector labelled as
“Output”
(X36
o
)
, in any of the equipments of the system and
insert the HDB15 male connector located in the opposite end of
the bundle into the female connector labelled as “Input”
(X36
i
)
of the adjoining equipment.
• Repeat the previous step with each equipment of the system,
till closing the communication BUS loop or ring.
• As an example, Fig. 38 shows, how the communication BUS
connections have to be done.
Although this illustration is not representative for the complete
SLC CUBE3+
series, as for the format of the cabinet, terminal
layout or size and/or switches, as well as the own communica-
tion ports, it expects to be a guide to clarify the possible doubts
