5.2.9.1. Terminal strip, auxiliary contact of manual bypass
switch (X51).
• Terminal strip (X51) of two pins of the UPS, is connected in par-
allel with the normally opened auxiliary contact of the switch or
manual bypass switch of the equipment.
• Switchgear panel board with manual bypass manufactured by
us (option), there is a terminal strip of two terminals connected
in parallel with the normally opened auxiliary contact of the
switch or manual bypass switch of the own switchgear panel
board. Any auxiliary contact of the manual bypass are moved on
in advance when closing.
• In case of acquiring a switchgear panel board
with manual bypass in another way, check that it
has the stated auxiliary contact and connect it to the
terminal strip (X51) of each equipment. As a must, the
auxiliary contact has to be moved on in advance when
closing.
• It is ESSENTIAL as safety measure of the system,
loads included, to connect the terminal strips (X51) of
the UPSs with the terminal strip with the same functionality of
the switchgear panel board. This way, any wrong action
over any switch or manual bypass switch of the turned
on UPSs will avoid causing a total or partial fault of the
installation, loads included.
5.2.9.2. Terminal strip, auxiliary contact of output switch
(X45).
• This terminal strip of two pins is available in any equipment, but
it is useful in parallel systems only.
• Basically, the normally opened auxiliary contact of the output
switch, is extended till the terminal strip of two pins (X45).
Through the isolated cable as a bridge mode that is supplied
connected between both pins, the circuit is closed. Do not re-
move in single equipments, because although the equipment
would be in operation, there would be an alarm of output switch
deactivated.
• In those installations with parallel systems, the cable as a bridge
mode connected between the two pins of the terminal strip
(X45) of each UPS has to be removed, and connected to the ter-
minals corresponding to the auxiliary contact of the output switch
of the switchgear panel board.
• In case of acquiring a switchgear panel board by
yourself, check that the output auxiliary contact
is available and connect it to the terminal strip (X45) of
each equipment. As a must, the auxiliary contact has to
be moved on in advance when opening.
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
SALICRU
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).
5.2.9.4. Ethernet connectors (X34
the battery cabinet. For separate battery cabinets and
probe bundle > 5 m, only.
• For those installations, where the distance between the UPS
and batteries needs a temperature probe bundle higher than 5
m. length, the connector (X34) described in the previous section
5.2.9.3. cannot be used, so the connector (X34
instead.
Although, regarding operation to compensate the floating voltage
according to the ambient temperature, there is no difference,
but the connection between cabinets needs the installation of
the option electronic card in the battery cabinet. In this card,
the (X38 ) connector has to be connected the communica-
ETH
tion channel bundle of 8 wires to its counterpart in the UPS
(X34 ).
ETH
Use the cable glands (PR) included in the base of the both cabi-
nets to pass the communication cable from inside to outside of
the equipment, depending on the point of view.
At the same time the own temperature probe is connected
to the optional electronic card and placed inside the battery
cabinet.
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.
