5.2.4. Connection to the optional battery module
(backup extension).
Failure to comply with the instructions in this
•
section and Safety Instructions EK266*08 car-
ries a high risk of electric shock and even death.
SPS ADVANCE R2 and T devices incorporate the batteries in
•
the same box as the device, except for SPS ADVANCE T B1
devices.
IMPORTANT FOR SAFETY: If batteries are installed
•
independently, the accumulator group must be fitted
with a bipolar circuit breaker or disconnect fuse of the size indi-
cated in Tab. 3.

Tab. 3. Protection features between device and battery module.
Before starting the connection process between the
•
battery module or modules and the device, check that
the UPS and the loads are set to 'Off' and that the battery
voltage of all of them is the same, without exceptions.
Also, when the batteries are installed by the user indepen-
dently, the protection fuse or isolator must be deactivated.
Connection of the battery module to the UPS is made by means
•
of a cable featuring polarised connectors at both ends and sup-
plied with the first one.
Plug the connector at one end of the cable into the corre-
sponding socket on the SPS ADVANCE T and the one on the
other end into the battery module (see Fig. 9).
In the same way, battery modules can be linked in parallel
since each of them has two connectors.
All of the connectors must be secured to their units by means
of the screws that held the protective cover of each connector
to the UPS or battery module.
Each battery module is independent for each device.
•
Two devices must not be connected to the same
battery module.
Fig. 9 shows, by way of example, the connection of a 3 kVA
•
device to two battery modules. For a larger number, proceed in
a manner similar to those shown in the illustration.

5.2.5. Terminals for EPO (emergency power off).
The UPSs have two terminals for the installation of an external
•
emergency power off (EPO) output button.
50
The device is dispatched from the factory with its EPO circuit
•
63
set to closed (NC) by default. In other words, the UPS will cut
100
the output power supply, emergency power off, when the cir-
63
cuit is opened:
Either by removing the female connector from the socket
ˆ
where it is inserted. This connector has a cable connected
as a jumper that closes the circuit (see Fig. 10A).
Or by pressing the button external to the device belonging
ˆ
to the user installed between the terminals of the con-
nector (see Fig. 10B). The connection on the button must
be in the normally closed contact (NC), so it will open the
circuit when activated.
To recover the normal operating state of the UPS, it is neces-
•
sary to insert the connector with the jumper in its receptacle
or deactivate the EPO button. The device will be operational.

5.2.6. Communication port.
5.2.6.1. RS232 and USB port.
The communications line -COM- constitutes a very low
•
voltage safety circuit. To preserve the quality, it must
be installed separately from other lines carrying dangerous
voltages (power distribution line).
The RS232 and USB interfaces are useful for the monitoring
•
software and updating the firmware.
It is not possible to use both the RS232 and USB ports at the
•
same time.
The RS232 port consists of the transmission of serial data in
•
such a way that a large amount of information can be sent
through a 4-wire communication cable.
