Note:
1. Rectifiers operate at any of the rated supply voltages and frequencies without further adjustment.
2. At 305 V mains input, the UPS maintains the specified output voltage at rated load without discharging a previously charged battery.
3. IEC62040-3/EN50091-3: At rated load and input voltage 400 V, battery charged.
4. IEC62040-3/EN50091-3: At rated load and input voltage 400 V, battery charging at maximum rated power

Note:
1. At low input voltage the UPS recharge capability increases as the load decreases (up to the maximum capacity indicated).
2. Max currents listed are for EOD voltage of 1.67 V/cell for 240 cells
