External Communications for the UPS
One of the multiple module units in the system serves as the processor for the external communications. The system cabinet has a parallel cabinet interface board with a rotary switch. The rotary switch allows the user to select the MMU that will be used for external communications. External communications can be done via one of the following methods: RS-232/RS-485 port, Ethernet, Modem, Modbus, SNMP, Dry Contacts, Remote Emergency Power Off and Remote Status Panel. For additional information, refer to Operation and Maintenance Manual, SEBU8144 and Operation and Maintenance Manual, SEBU8145.
