3.Warning LED (Red LED): When in AC or DC mode, the blinking LED could indicate that the battery should be replaced. When the LED is always on, it indicates an overload condition or UPS fault. For details, see the Indicator Table.
4.Surge Protection Outlets (Bypass Outlets): These outlets provide protection from surges and spikes.
5.Battery Backup & Surge Protection Outlets: These outlets not only provide surge protection, but also provide emergency battery backup power.
6.Phone/Fax Protection: Built-in RJ-11 jacks protect the phone or fax line from surges. (Model 168229 only.)
NOTE: The UPS will operate normally without this connection.
7.USB Communication Port: The built-in USB port (Model 168229 only) connects to your computer. The software will shut down your computer automatically in case of power failure and prevent possible file damage due to an abrupt power outage. The software can also provide information regarding the status of your utility power line. Install the software: If auto play is not enabled on the computer, double-click on My Computer on the desktop; double-click on the CD-Rom drive icon and follow the on-screen instructions.
8.Circuit Breaker: The button will protrude when an overload occurs. The UPS will switch off of utility power. If the button protrudes, disconnect some non-essential equipment and reset the circuit breaker by pushing the button in.
9.AC Power Cord: Complete the necessary power connections. For North American models (120 V), use an existing NEMA-type PC power cord to connect the PC to the UPS. Use the included NEMA-type power cord to connect the UPS to the power source. For all other models (230 V), use the included IEC-type power cord to connect the PC to the UPS. Use one of the existing PC power cords to connect the UPS to the power source.
