Remote Power Off (RPO).
The UPS have two terminals for the installation of an external
Remote Power Off -RPO- button.
By default, the unit is issued from the factory with the closed
RPO circuit type -NC-. The UPS will cut the output power supply,
emergency stop, by opening the circuit:
Either by removing the female connector of the socket where
•
it is inserted. This connector has a cable connected as a bridge
that closes the circuit.
Or by activating the unit's external button, which belongs to
•
the user and is installed between the connector terminals. The
connection on the button must be in the normally closed (NC)
contact, so the circuit will open when it is activated.
Except in specific cases, we do not recommend connection to the
open RPO circuit type -NO-, since it will not act in the event of an
emergency requirement if either of the two wires leading from the
pushbutton to the UPS is accidentally disconnected..
On the other hand, this anomaly would be detected immediately
in the closed RPO circuit -NC-, with the drawback of an
unexpected power cut to the loads, but with the guarantee of
effective emergency functionality.
To recover the normal operating status of the UPS, it is necessary
to insert the connector with the bridge into its receptacle or
deactivate the RPO button. The unit will be operational.
When the RPO is activated, the UPS cuts off the output immediately
and issues the alarm.

5.3.6.6. Intelligent slot.
The UPS has a slot on the back to insert one of the following
communication cards (see Fig. 9 to Fig. 11).
Integration into computer networks using an SNMP
•
adapter.
Large LAN and WAN-based computer systems that integrate
servers on different operating systems must provide the
system administrator with ease of control and management.
This is achieved through an SNMP adapter, which is universally
supported by the main software and hardware manufacturers.
The connection of the UPS to the SNMP is internal, while the
connection of the SNMP to the computer network is via an
RJ45 base10 connector.
