5. Setup

1. Initial Battery Connection: The UPS is shipped with the battery disconnected for safety. Locate the battery compartment (usually on the bottom or rear) and connect the battery terminals as instructed in the quick start guide or on the unit itself.
2. Connect to Utility Power: Plug the UPS power cord directly into a grounded 120V wall outlet. Do not use surge protectors or extension cords. Allow the UPS to charge for at least 8 hours before connecting equipment to ensure full battery capacity.
3. Connect Equipment:
   • Plug critical equipment (computer, monitor, external hard drives) into the Battery Backup Plus Surge Protection outlets.
   • Plug non-critical equipment (printer, scanner, speakers) into the Surge Protection Only outlets.
4. Connect Data Line Protection (Optional): If desired, connect your phone/fax line or network cable through the respective ports on the rear of the UPS to protect against surges.
5. Install Power Management Software (Optional): Use the provided software CD and USB cable to install APC PowerChute Personal Edition software on your computer. This software allows for automatic graceful shutdown during extended power outages and provides advanced power management features.

6. Operation

Turning the UPS On/Off:

• To Turn On: Press the power button on the front panel. The 'On Line' indicator will illuminate.
• To Turn Off: Press and hold the power button until the UPS beeps and all indicators turn off.

Self-Test:

To perform a self-test, ensure the UPS is connected to utility power and press the power button briefly. The UPS will switch to battery power for a few seconds, then return to utility power. This tests the battery and internal circuitry.

Understanding Alarms:

• On Battery: A steady beep indicates the UPS is operating on battery power.
• Low Battery: Rapid beeping indicates the battery is running low and connected equipment should be shut down.
• Overload: A continuous tone indicates an overload condition. Disconnect non-essential equipment immediately.

7. Maintenance

Battery Replacement:

The APC Back-UPS CS 500 uses a sealed lead-acid battery. The 'Replace Battery' indicator will illuminate when the battery needs replacement, typically every 3-5 years depending on usage and environmental conditions.

Caution: Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the manufacturer's instructions and local regulations.

1. Turn off the UPS and disconnect it from the wall outlet.
2. Disconnect all connected equipment.
3. Access the battery compartment (refer to your specific model's instructions for location).
