How to use

Plug critical devices into the provided AC outlets. When mains power fails, the UPS will switch to battery power automatically; monitor load to avoid exceeding the 550 W output rating. Use the cold-start function to power devices from battery if mains power is not available.
Usage recommendations
For reliable protection, reserve the UPS for essential devices only, keep total connected load below the rated 550 W, and perform periodic battery checks. Replace batteries according to manufacturer guidance or when runtime noticeably decreases.
