9.2.4 RS485 Interface for remote panel – JR3
JR3 is used by the TFT touch-screen display and control unit.
9.2.5 SNMP Card slots
Simple Network Management Protocol (SNMP) is a world-wide, standardised communication protocol that can be used to
monitor any network-connected device via a simple control language and display the results in an application running
within a standard web browser.
The customer interface board contains two SNMP/CS141 slots; one is designed to house a Modem/Ethernet SNMP
adapter card and the other a Modem/GSM adapter. SNMP connectivity can also be implemented using an external SNMP
adapter connected to the UPS RS232 output (JD11), as shown in Figure 9.6.
The SNMP/Ethernet adapter is fitted with an RJ-45 connector which allows it to be connected to the network using a
standard CAT-5 network cable. Once connected, the UPS-Management software agent installed in the SNMP adapter,
then monitors the UPS operation and outputs its data in SNMP format to the connected network. In a multi-module UPS
system the SNMP interface can communicate ‘system-wide’ data or data for an individual UPS module.
The SNMP adaptor requires a PC with terminal connections, and for normal operation at least one Ethernet connection.
The SNMP card can be configured to send event/alarm emails, provide controlled server shut down (with optional
licenses) and perform other tasks that can be integrated with BMS software over a local area network (LAN) for SNMP, or
Modbus information over IP. An optional card is available to enable Modbus communications over RS485.

UPS Monitoring and automated control software
9.3.1 The importance of UPS management
The utility supply is inevitably unreliable every now and then; and assuring continuous power to all the facilities connected
to it can be a difficult task. The situation is further complicated if worldwide systems are managed via a Local Area
Network (LAN) or Wide Area Network (WAN).
However, by using the PowerWAVE 9500DPA UPS system in conjunction with purpose-designed network management
tools, a System Administrator can take measures to back-up data and prevent system errors or data loss even in the event
of a relatively long utility supply outage. In the case of an abnormal utility supply, suitable UPS management software can
also enable a System Administrator to monitor all concerned networks from a central point and identify bottlenecks at an
early stage.
In spite of extensive system monitoring, serious damage can still occur if an administrator fails to intervene in a timely
manner, and it is therefore important that the installed UPS software reacts automatically in such an event and shuts down
the supplied system in a safe and controlled manner.
Kohler Uninterruptible Power Ltd.considers it important to have a complete solution for its UPS systems, and offers its
customers a number of remote control and monitoring tools to provide optimum protection.
