connected to a common neutral bar (blue terminal blocks). The system is shipped with a shorting link installed that
connects all the active terminals together, thereby making the system a single supply, single phase load.
For Power shelves with AC distribution, unless specially ordered, the AC active feeds to the circuit breakers are
connected to one of three terminal blocks (beige). The un-switched AC lines to the rectifiers are tied together on a
common neutral bar (blue blocks). The wiring is arranged this way to allow the system to be configured easily for
single phase or three phase “Y-connection” supply. The system is shipped with a shorting link joining the three
active terminations, thereby making the system a single supply, single phase load by default.
The shorting link/s must be removed before connecting a 3 phase supply. The label over the AC terminations
indicates the L1, L2, L3, N, GND connections to indicate how the Power shelf with AC distribution is wired. AC
feed wiring should be sized appropriately per NEC code for the number of rectifiers being powered.
3.3.2 Single phase – individual protected external feeds
Connect each of the circuit breaker protected active wires to the individual terminal blocks that feed each rectifier.
Remove the shorting link from the active terminal blocks (“A” block). Connect the neutral wire/s to the common
neutral terminals.
