Warranty coverage typically requires the system to be commissioned by a manufacturer-approved engineer. Technical Specifications & Performance
Via the control panel, command the rectifier to start. The DC bus voltage will rise to its nominal operating level.
The Hipulse D manual clearly defines the UPS’s behavior in each mode:
The user manual dictates specific sequences for starting and stopping the unit. liebert hipulse d ups manual
Close the . The rectifier will start up automatically (indicated by a ramping DC bus voltage). Turn on the external Battery Bank Circuit Breaker .
For immediate needs, start with the inside the main manual, then proceed to the Installation and User Manual for your specific kVA rating. If the manual is lost, contact Vertiv support with your unit’s model code (e.g., HIPULSE D 300-500kVA) to request a digital replacement.
The system is designed for high reliability with a lifespan of 15–20 years when properly maintained. Warranty coverage typically requires the system to be
, which protects the connected load and the DC circuit from any mains disturbances or transients. Customizable Battery Management:
The front fascia features a comprehensive Liquid Crystal Display (LCD) mimic panel, status LEDs, and tactile control buttons. Primary Menu Structure
Manually initiate a transfer to static bypass via the control panel interface. The Hipulse D manual clearly defines the UPS’s
If utility power fails or deviates outside acceptable voltage tolerances, the rectifier shuts down. The inverter instantly draws DC power from the battery bank. There is zero transfer time, ensuring uninterrupted load operation. Bypass Mode
Rectifier control loop malfunction or high ambient temperature.
If the UPS experiences an internal fault, component overheating, or a severe output overload, the internal static switch automatically transfers the critical load to the bypass utility line. This transition is synchronized and instantaneous, ensuring the load remains energized while isolating the internal circuitry for safety. Maintenance Bypass Mode (Manual)
Always wear appropriate Personal Protective Equipment (PPE), including flash-rated clothing, safety glasses, and insulated gloves.
