NOTE
You need to provide 3 DC power lines for the NEPS5000-D. If a device is equipped with double NEPS5000-
D power modules, 6 DC power lines are required. The 6 DC power lines of the power distribution frame
(PDF) are directly connected to power module A and power module B.

Note
To protect power supplies of
different levels, it is
recommended that the
current of the circuit breaker
on the user side should be
greater than or equal to that of
the circuit breaker of the
power module (60 A).
To support the maximum
configuration, it is
recommended that each DC
power line should provide a
minimum of 44 A @ -48
VDC current.
