Each shelf has two negative inputs (A and B), and two
connections to a positive common input. Half the converters
are powered by Feed A and half by Feed B as listed in the
following table.
Alpha recommends that each converter shelf have two
dedicated input feeder breakers, if both A and B feeds are
used.
Refer to the specifications in Section 3 on page 10f or
recommended breaker and cable sizes. Local electrical
codes take precedence.
