If the inverter capacity is exceeded (overload) or an internal hardware failure occurs, the UPS logic activates the static switch. The load transfers instantly to the bypass AC source. Maintenance Bypass Mode
Store the PDF on a local drive accessible via building management network. Keep a paper copy in a fire-safe cabinet near the battery room.

Maintain an ambient temperature between 0°C and 40°C. Optimal battery performance is achieved at 20°C–25°C.
Verify correct phase rotation (L1, L2, L3) for both the main rectifier input and the bypass input. Incorrect phasing will trigger a system fault and prevent startup.
An output transformer that provides galvanic isolation, mitigating harmonic distortion and protecting the load from spikes. 2. Technical Specifications Specification Details Topology Online Double-Conversion (True Sine Wave) Input Phase 3-Phase, 4-Wire + Earth Output Phase 3-Phase, 3-Wire or 4-Wire + Earth Output Power Factor
The inverter utilizes pulse-width modulation (PWM) technology to convert DC power back into a clean, regulated AC sine wave. This ensures the output remains completely unaffected by utility frequency shifts, voltage sags, or harmonic distortion. Static Bypass Switch
