7.9.2.- Connector (C14) USB interface.
• The communication line (interface) constitute a safety circuit of very low voltage. To preserve this quality, they should
be installed separated from other lines with dangerous voltages (like distribution lines of energy).
• The UPS connection to your computer can be carried out through the USB communication port.
It will be necessary a hardware and an operating system that allows the communication for this port, including the installation
of a
UPS controller. The RS-232 series port cannot be used when the USB channel is used.
7.9.3.- Connectors RJ-45 for ETHERNET networks (C12) and (C13).
• This connection is not necessary for the UPS operating, and it is only limited to the protection against transient voltages.
• Connect the input line (server side) of the IT network to the connector (C12) .
• Connect the output line (user side) of the IT network to the connector (C13) .
The ETHERNET network can become inoperative in case of doing an incorrect connection.
7.9.4.- Software.
7.9.4.1.- Basic structure for installing the «UPSMON» software.
• PC with a free serial port (COM1 to COM4).
7.9.4.2.- Hardware installation.
• Turn off the PC and the monitor.
• Check that the basic structure is at least as indicated in section 7.9.4.1
• Connect the cable between the PC (SUB-D9 male) and the UPS (SUB-D9 female). If the serial port in the PC is a male SUB-
D25, use a female SUB-D25 to male SUB-D9 adapter.
• Connect the PC (load) to the UPS, respecting the stated instructions.
• Start the UPS following the instructions in chapter 8. The UPS can be used as a central start - stop unit.
• Start the PC and the monitor.
• Before communications can be established between the UPS and the computer, the Config./COM serial port must be select-
ed and select the COM port to which the UPS has been connected too. The indicators of the panel of the «UPSMON» will be
visualised, and the parameters and conditions of the UPS will be shown in real time.
7.9.4.3.- «UPSMON» Software.
• The monitoring software is used together with the RS-232 interface to carry out control functions (diagnostic of voltage,
frequency, battery level, etc.) and to facilitate an ordered Shutdown by levels in case of mains failure.
