UPS installation is the process of safely and correctly setting up an uninterruptible power supply system to provide backup power during outages. It involves several key steps, including determining power needs, choosing a suitable location with proper ventilation, and securely connecting the UPS to both the main power source and the devices it will protect. Due to the high voltages and specialized nature of these systems, professional installation by a qualified electrical contractor or the manufacturer is highly recommended to ensure safety, reliability, and proper functionality.
