AC Input Panels (continued)
Field Modification of the 1-Phase Circuit Breaker AC Panel for use with Phase-
Neutral Input Circuits - ED83142-30 G7 or G28
For ED83142-30 G7 or G28 only:
When connecting the AC panels to a 380-480V, 3W+N+PE source, where neutral is required to obtain the
correct 176-277Vac L-N input voltage for each rectifier position, the panels must be converted from
their factory-shipped phase-to-phase rectifier connection to a phase-to-neutral connection.
Order kits per the table that follows and modify the panel as shown in Figure 7-21.
