Manual resets are required after a controlled transfer to bypass or an action. Key Technical Features & Indicators
Disconnect all AC and DC sources before servicing. Check for residual voltage using both AC and DC voltmeters.
: Address the root cause (e.g., reduce the load if there was an "Output Overload" alarm).
Maintenance must only be performed by . High earth leakage current is present, and internal components remain potentially lethal even after the AC input is disconnected. Always ensure the unit is earthed according to local codes. 1. Understanding Mimic & LCD Indicators
If the problem persists, do not attempt to bypass internal safety protocols. Contact a certified Vertiv/Liebert service engineer for assistance, especially for: DC capacitor bank failures. Inverter IGBT module failures. System controller card issues.
Navigate the on the LCD; readings for input amps and output volts should appear as the system ramps up.
Normal transitions (e.g., "On Inverter").
