• Connectivity Cards
Connectivity cards allow the UPS to communicate in a variety of networking environments and with
different types of devices. The 9PX models have one available communication bay for the following
connectivity cards:
• Network-MS card (standard) - has SNMP and HTTP capabilities as well as monitoring through a
Web browser interface; connects to Ethernet network. In addition, a Environmental Monitoring
Probe can be attached to obtain humidity, temperature, smoke alarm, and security information.
• Modbus-MS card - has connection to Modbus protocol in addition to network management.
• Relay-MS card - has isolated dry contact (Form-C) relay outputs for UPS status: Utility failure,
Battery low, UPS alarm/OK, or on Bypass.
See "Installation of the communication cards", on page 34 for the location of the communication bay.
