Each battery module is independent for each equip-
ment. It is completely forbidden to connect to equip-
ments to the same battery module.

Specifications of the protection between the equipment and
battery module.
4.3.4. Connection of main input earth
terminal
(
terminal
(
As this is a device with class I protection against elec-
tric shocks, it is essential to install a protective earth
conductor (connect earth(
the terminal, before connecting the power supply to the input
power block.
Make sure that all the loads connected to the UPS are only
connected to the protective earth bonding terminal (
fact of not restricting the earthing of the load or loads and/or
the batteries case/s or cabinet/s to this single point will create
a return loops to earth which will affect the quality of the sup-
plied power.
All terminals identified as earth bonding (
together, to the main protective earthing terminal (
to the frame of the device.
4.3.5. EPO terminals in UPSs > 1kVA
(Emergency Power Off).
All UPSs have two terminal to install an external button, for
Emergency Power Off (EPO).
As an illustration mode, figures A and B, it is shown a con-
nector of two pins.
By default, the equipment is supplied from factory with the
EPO circuit as open (NO). So, the UPS will break the output
power supply, emergency power off, when opening the cir-
cuit:
Either by removing the female connector inserted in the
plinth. This connector has a cable bridge to close the cir-
cuit (Fig. A).
Fig. A
Or by turning on the external button installed and be-
longing to the end-user. The connection in the button has
to be in normally closed because it will open the circuit
when turning it on.

Through the control panel, it can be selected the reverse
functionality, normally closed (NC).
Less punctual cases, it is not recommended to use this type
of connection due to the function of the EPO button, because
it would not work in case of any of the two cables that goes
from the button to the UPS were cut (damaged).
On the other hand this failure would be immediately detected
in the normally open EPO type, with the inconvenience of
the sudden break in the power supply to the loads, but with
a complete guarantee of the functioning of the emergency
power off.
To restore the normal operating mode of the UPS, the con-
nector with the cable bridge has to be fitted back in the terminal
strip or to deactivate the EPO button and later on to cancel the
EPO status in the control panel . The equipment will be opera-
tive.
4.3.6. Communication port.
4.3.6.1. RS232 and USB interface.
Communication line (COM) is a very low voltage circuit
of safety. To preserve the quality, it has to be installed
separate from other lines that have dangerous voltages (energy
distribution line).
RS232 and USB interfaces are used by the monitoring soft-
ware and firmware updating.
It is not possible to use both ports at the same time.
Signal pin-out of the DB9 connector are shown in table 4. In
the connector, the RS-232 signal and dry contacts through
optocouplers can be found.
RS232 port consists in a serial data transmission, so an im-
portant quantity of information can be sent through a com-
munication cable of 3 wires.

4.3.6.2. Smart slot.
UPSs have a unique slot, hidden rear the cover stated in the
views of the equipment as "Smart slot", and allows inserting
any of the following options cards:
SNMP for control via Web.
Remote UPS management through Internet or Intranet.
