Round the value of QS to the next highest integer. This number
represents the number of IEPAS02 power modules needed to
satisfy system requirements.

QS
= 5 - 4 = 1 IEPAF02 module
Number of IEPAS02 power modules required for the system.
QS
= 4 IEPAS02 modules
With N+1 redundancy where N = QS.

N
+ 1 = 5 IEPAS02 modules
MAXIMUM POWER ENTRY PANEL CURRENT DRAW
Use the value of Q5 × 30 (total power from the modular power
system sizing procedure) to determine if your system is within
specification of the power entry panel. The following equations
show how to determine the current draw on the power entry
panel.
for 120 VAC systems.
for 240 VAC systems.
The resulting quotient is the maximum current draw on the
power entry panel. The specified current limits on the power
entry panel are:
•
20 amps for 120 VAC systems.
•
10 amps for 240 VAC systems.
