Appendix A Power Supply Specifications
4200 W AC-Input Power Supply
Power supply output
capacity
The power supply output capacity is dependent on the number of AC
power cords (1 or 2) attached, the source AC voltage (110
VA C
[low-line] or 220
VAC [high-line] applied to the power supply inputs,
and the number of power supply power switches switched on or off.
Note If source AC is applied to both two inputs, both inputs should
have the same AC voltage.
1050 W operation 1050 W maximum with the following combinations of power cords and
source AC voltage applied to the power supply inputs:
• One AC input is connected to low-line (110 VAC nominal); the
second AC input is not connected to source AC or is switched off.
2100 W operation 2100 W maximum with the following combinations of power cords and
source AC voltage applied to the power supply inputs:
• Both AC inputs are connected to low-line (110 VAC nominal) and
both inputs are switched on.
• One AC input connected to high-line (220 VAC nominal); the
second AC input is not connected or is switched off.
4200 W operation 4200 W maximum with the following combinations of power cords and
source AC voltage applied to the power supply inputs:
• Both AC inputs are connected to high-line (220 VAC nominal) and
both inputs are switched on.
