NOTE: Heat dissipation is calculated using the PSU wattage rating.
NOTE: This system is also designed to connect to the IT power systems with a phase-to-phase voltage not exceeding
240 V.
NOTE: If a system with 24000 W AC PSU operates at low line 100-120 V AC, then the power rating per PSU is derated to
1400 W.
NOTE: If a system with 2000 W AC PSU operates at low line 100-120 V AC, then the power rating per PSU is derated to
1000 W.
NOTE: If a system with 1600 W AC PSU operates at low line 100-120 V AC, then the power rating per PSU is derated to
800 W.
NOTE: If a system with 1100 W AC PSU operates at low line 100-120 V AC, then the power rating per PSU is derated to
1050 W.
