Below these indicators is a circular power button. The text 'Back-UPS CS 350' is visible, along with the APC logo and website 'www.apc.com' at the bottom.
Front Panel Indicators:
- On Line (Green LED): Illuminates when the UPS is supplying conditioned utility power to connected equipment.
- On Battery (Amber LED): Illuminates when the UPS is supplying battery power to connected equipment during a power outage or brownout.
- Overload (Red LED): Illuminates when the connected equipment exceeds the UPS's capacity. An audible alarm may also sound.
- Replace Battery (Red LED): Illuminates when the battery needs to be replaced.
Rear Panel Connections:
- Battery Backup & Surge Protected Outlets (3): These outlets provide battery power during outages and surge protection. Connect critical equipment like your computer, monitor, and external hard drive here.
- Surge Only Outlets (3): These outlets provide surge protection only. Connect non-critical equipment like printers or scanners here.
- RJ11 Modem/Fax/DSL Protection: Ports for protecting phone/data lines from surges.
- USB Port: For connecting the UPS to your computer to use PowerChute software.
- Input Power Cord: Connects the UPS to a wall outlet.
4. Setup
- Unpack and Inspect: Carefully unpack the UPS and inspect it for any shipping damage.
- Connect Battery: The battery may be disconnected for shipping. Refer to the battery compartment instructions (usually on the bottom or rear of the unit) to connect the internal battery.
- Initial Charge: Plug the UPS power cord into a grounded wall outlet. Allow the UPS to charge for at least 8 hours before connecting equipment to ensure full battery capacity. The 'On Line' indicator should illuminate.
- Connect Equipment:
- Plug your computer, monitor, and other critical equipment into the Battery Backup & Surge Protected outlets.
- Plug non-critical equipment (e.g., printer, scanner) into the Surge Only outlets.
- For phone/data line protection, connect your phone line from the wall to the 'IN' port on the UPS, and then from the 'OUT' port on the UPS to your phone/modem.
- Install PowerChute Software (Optional but Recommended): Connect the supplied USB cable from the UPS to your computer. Install the PowerChute software from the included CD or download it from the APC website. This software allows for automatic shutdown of your computer during extended power outages and provides advanced power management features.
5. Operating Instructions
