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
•
parallel 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 terminals 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
USER'S MANUAL
the cabinet itself when batteries and equipment are fitted in
the same enclosure.
For those cases that batteries are supplied in a separate cab-
inet 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
and (X38 ) in the battery cabinet. For
ETH
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
will be used 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 cab-
inet. In this card, the (X38
ETH
the communication channel bundle of 8 wires to its counter-
part in the UPS (X34 ).
ETH
Use the cable glands (PR) included in the base of the both
cabinets to pass the communication cable from inside to out-
side 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 oper-
•
ating, any unit connected in parallel are continuously com-
municated among them. It is achieved by means of the called
communication 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.
