Setup Instructions
Unpacking
Carefully remove the UPS unit and all accessories from its packaging. Inspect the unit for any signs of damage. Retain packaging for future transport or storage.
Connecting the UPS
- Connect the UPS power cord to a properly grounded 120-Volt AC outlet.
- Connect your critical equipment (e.g., computer, monitor, router) to the 'Battery Backup & Surge Protected' outlets. These outlets provide power during outages and protect against surges.
- Connect non-critical equipment (e.g., printer, scanner) to the 'Surge Only' outlets. These outlets provide surge protection but no battery backup.
- For network manageability, connect the RJ-45 Serial or USB cable from the UPS to your computer or network device.

Always power off the UPS and disconnect it from the wall outlet before attempting battery replacement. Follow the specific instructions provided in the full product manual for safe and proper battery module installation.
Cleaning
Regularly clean the exterior of the UPS with a dry cloth. Ensure ventilation openings are free from dust and debris to maintain proper airflow and prevent overheating. Do not use liquid cleaners or solvents.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| UPS does not turn on | Not connected to AC power; Battery not connected or discharged | Ensure power cord is securely plugged into a live AC outlet. Connect the internal battery. Allow 24 hours for initial charge. |
| UPS beeps frequently | On battery power; Overload condition; Low battery | Check AC power. Reduce connected load. Allow battery to recharge. |
| Short runtime on battery | Battery is weak or old; Overload condition | Replace battery module. Reduce connected load. |
| UPS makes a buzzing sound | Normal operation during battery mode or AVR adjustment | This is often normal. If persistent and loud during normal AC operation, ensure proper ventilation and check for loose components. |
