Modular design Provides fast serviceability and reduced maintenance requirements via self-diagnosing, field-replaceable modules. Configurable for N+1 internal redundancy Provides high availabilty through redundancy by allowing configuration with one more Power Module than is necessary to support the connected load. Redundant Intelligence Modules Provides higher availability to the UPS connected loads by giving redundant communication paths to critical UPS functions. Hot-swappable intelligence modules Ensures clean, uninterrupted power to protected equipment during Intelligence Module replacement. Hot-swappable power modules Ensures clean, uninterrupted power to protected equipment during Power Module replacement. Hot-swappable batteries Ensures clean, uninterrupted power to protected equipment while batteries are being replaced Power Modules connected in parallel Enhances availability by allowing immediate, seamless recovery from isolated module failures. Battery modules connected in parallel Delivers higher availability through redundant batteries. Automatic internal bypass Supplies utility power to the connected loads in the event of a UPS overload condition or fault. Automatic restart of loads after UPS shutdown.
