5. Setup
Follow these steps to set up your Nilox UPS:
- Unpacking: Carefully remove the UPS from its packaging. Inspect for any shipping damage.
- Placement: Place the UPS on a flat, stable surface in a clean, dry, and well-ventilated area. Avoid direct sunlight, heat sources, and excessive dust.

The UPS contains a 5Ah battery that is easily replaceable. Over time, batteries lose their capacity. If you notice a significant reduction in backup time, the battery may need replacement. Refer to the manufacturer's guidelines or contact customer support for compatible replacement batteries and instructions.
Warning: Battery replacement should only be performed by qualified personnel. Improper replacement can lead to hazards.
7.2. Cleaning
Regularly clean the exterior of the UPS with a soft, dry cloth. Do not use liquid or aerosol cleaners. Ensure ventilation openings are free from dust and debris to maintain proper airflow.
