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 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 system with 1100 W AC PSU or 1100 W Mixed Mode HVDC PSU operates at low line 100–120 V AC, then the power
rating per PSU is derated to 1050 W.
