Its manual is not a single document but a structured set of technical publications essential for safe installation, operation, maintenance, and troubleshooting.

Troubleshooting (common issues)

• UPS alarm with “On Battery” while mains present — check input wiring and voltage; possible transfer/rectifier fault.
• Short runtime — battery aging or insufficient battery capacity; run battery test and replace as needed.
• Overload alarm — reduce load or upgrade to correct capacity model.
• UPS not starting — check input breaker, battery connections, and emergency stop/bypass state.

3.1 Identify Your Exact Model Number

The manual varies by:

• Power rating (e.g., 120 kVA vs 400 kVA)
• Pulse number (6-pulse or 12-pulse rectifier)
• Voltage class (400V EU / 480V US)

Look for a silver rating plate on the door. The correct SKU (e.g., Hipulse D 100-400V-6P) will direct you to the right document.

Q4: What does “static bypass overload” mean?

Manual answer: The load exceeds 125% of nominal, and the inverter transferred to bypass. The manual states that if the overload persists for >30 seconds, the bypass will trip. Reduce load immediately. liebert hipulse d ups manual
