NOTES ON TABLES.
Notes apply to
1.
Nominal input current (considered continuous) is based on full rated output load maximum current includes nominal input current and maximum battery recharge current (considered noncontinuous). Continuous and noncontinuous current are defined in the NEC 100. Recommended overcurrent protection is based on 80% rated devices.
*The recommended overcurrent protection represents 125% of nominal full load current (continuous) per the
NEC 215.
2.
The maximum input current is controlled by the current limit setting.
3.
The recommended AC input external overcurrent protection is based on 80% rated devices and maximum input current limit setting.
4.
The recommended AC output external overcurrent protection is based on 80% rated devices and full rated output current.
5.
The nominal battery voltage is shown at 2 volts per cell.
6.
The input power factor of 0.99 is used for the calculations.
