How to use

Place the UPS on a stable, level surface with adequate ventilation and connect it to a grounded mains outlet. Attach critical devices to the protected AC outlets and power them on. The UPS will provide surge protection while mains power is present and automatically switch to battery power if the input supply fails. Monitor load to avoid exceeding the 330 W output rating; for extended runtime or higher loads, use a UPS with greater capacity. Replace the internal battery according to the manufacturer’s recommended interval or when runtime noticeably decreases.

Recommendations

To extend battery life and ensure dependable operation, keep the UPS in a cool, dry environment, avoid placing it in direct sunlight or near heat sources, and perform periodic self-tests if the unit supports them. Use the four AC outlets for equipment that requires short-term protection and orderly shutdown rather than for long-term high-power loads.
