How to use

Mount the UPS in a suitable location near the devices requiring backup power, ensuring adequate ventilation and access for wiring. Connect the input to the AC supply and attach the output to the protected load according to the installation instructions and local electrical regulations. Verify battery connection and allow the unit to complete its initial charge cycle before relying on backup power. Perform regular visual inspections and functional tests to confirm readiness.

Recommendations

For reliable operation, place the UPS in a dry, dust-free environment with ambient temperature within the specified operating range. Schedule periodic battery tests and replace batteries according to the manufacturer's recommended intervals or when capacity declines. Ensure proper fusing and separation of critical circuits during installation to maintain safety and compliance with local standards.
