AC Receptacles: Your UPS features IEC-320-C13 outlets. These output receptacles provide your connected equipment with AC line power during normal operation and battery power during blackouts and brownouts. The UPS protects equipment connected to these receptacles against damaging surges and line noise.

Communications Ports (USB or RS-232): These ports connect your UPS to any workstation or server. Use with Tripp Lite’s PowerAlert Software and included cables to enable your computer to automatically save open files and shut down equipment during a blackout. Also use PowerAlert Software to monitor a wide variety of AC line power and UPS operating conditions. Consult your PowerAlert Software manual or contact Tripp Lite Customer Support for more information. See “USB and RS-232 Serial Communications” in the “Optional Installation” section for installation instructions.

Telephone/Network Protection Jacks: These jacks protect your equipment against surges over a telephone/network data line. Connecting your equipment to these jacks is optional. Your UPS will work properly without this connection.

Voltage DIP Switches: These switches enable the UPS to be set to match actual input voltage. If the Voltage DIP Switches are set above or below input voltage, the UPS will treat the input as a continuous overvoltage or undervoltage condition, and will automatically adjust input voltage to match the Voltage DIP Switch setting. This will cause constant, unnecessary wear on the UPS.

Note: The Voltage DIP Switches must be set with the UPS turned OFF and disconnected from utility power. If the switches are set while the UPS is connected to utility power, the setting will not take effect.

Accessory Slot: Remove the small cover panel from this slot to install optional accessories to remotely monitor and control your UPS. Refer to your accessory’s manual for installation instructions. Contact Tripp Lite Customer Support at (773) 869-1234 for more information, including a list of available SNMP, network management and connectivity products.

Input Breaker (SMX1500SLT): Protects your electrical circuit from overcurrent draw from the UPS load. If this breaker trips, remove some of the load, then reset by pressing the breaker in.

Fan: The fan cools the UPS's internal components. It operates only when the UPS is in battery backup mode, is charging its batteries or is carrying a heavy electrical load.
