NOTE
The NEPS5000-A power module can be connected to the AC PDF through the distribution box. After
passing through the distribution box, the 2 AC lines on the PDF are split into 6 AC lines to provide power
for two NEPS5000-A power modules.
The rated current of the circuit breakers (A2, A3, A4, B2, B3, and B4) on the AC distribution box is 20 A.
The current specifications of the circuit breakers (A1 and B1) on the PDF should be no less than 32 A.
The NEPS5000-A power module also can be connected to the AC PDF through the 3 AC lines on the PDF
to provide power for two NEPS5000-A power modules.
It is recommended that the current specifications of the circuit breakers on the PDF should be no less than
16 A (because the current specifications of the circuit breaker of the power module is 16 A).
lists the cables and terminals for the NEPS5000-A.
