Each battery module is independent for each device.
Two devices must not be connected to the
same battery module .
t
Fig. 9 shows the connection of a 3 kVA device in a rack
arrangement with two battery modules. For a larger number,
proceed in a manner similar to those shown in the illustration.

5.2.4. Terminals for EPO (emergency power off).
t
The UPSs have two terminals for the installation of an
external emergency power off (EPO) output button.
t
The device is dispatched from the factory with its EPO
circuit set to closed (NC) by default. In other words, the
UPS will cut the output power supply, emergency power
off, when the circuit is opened:
ˆ
Either by removing the female connector from the socket
where it is inserted. This connector has a cable connected
as a jumper that closes the circuit (see Fig. 10-A).
ˆ Or by pressing the button external to the device
belonging to the user installed between the terminals
of the connector (see Fig. 10-B). The connection on the
button must be in the normally closed contact (NC), so
it will open the circuit when activated.
The reverse functionality can be selected through the
communications software and control panel.
Except for specific cases, we advise against this type
of connection in view of the purpose of the EPO button,
since it will not act upon an emergency request if either
of the two cables that run from the button to the UPS is
accidentally cut.
By contrast, this anomaly would immediately be detected
in a closed EPO circuit, with the inconvenience of an
unexpected cut in the powering of the loads, but a
guarantee of effective emergency functionality.
t
To recover the normal operating state of the UPS, it is
necessary to insert the connector with the jumper in its
receptacle or deactivate the EPO button. The device will
be operational.

5.2.5. Communication port.
5.2.5.1. RS232 and USB port.
t
The communications line -COM- constitutes a very
low voltage safety circuit. To preserve the quality
must be installed separately from other lines carrying
dangerous voltages (power distribution line).
t
The RS232 and USB interfaces are useful for the monitoring
software and updating the firmware.
t
It is not possible to use both the RS232 and USB ports at
the same time.
t
The DB9 connector supplies the RS232 signals and the
normally open (NO) potential-free contacts using optocouplers.
The maximum voltage and current applicable to these
contacts is 30V DC and 1A.
Also, there is a «Shutdown» input that allows turning off
the inverter, when a voltage between 10 a 12 V is applied
for 1 second at this input.
t
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 communication cable with only 3 wires.
t
The USB port is compatible with the USB 1.1 protocol for
communication software.
