RPS6U 200-582-916-034 / RPS6U 200-582-993-022 form the cabinet-side input boundary at the rear of an ABE04x rack, so conductor type, external protection and feed separation follow the selected panel.

1. 01

   916 AC input panel

   RPS6U 200-582-916-034 presents two screw-terminal AC inputs and sends each feed through its own fuse and filter path. The panel has no mains switches, so isolation is provided by the external installation.

2. 02

   993 DC input panel

   RPS6U 200-582-993-022 presents two screw-terminal DC inputs with an individual input path for each front RPS6U supply. The DC panel does not add AC-style fuse protection, so the installation uses a correctly rated external breaker.

3. 03

   Rack position and access

   Both RPS6U 200-582-916-034 / RPS6U 200-582-993-022 mount at the rear of the ABE04x rack. Their terminals remain the service boundary between facility wiring and the internal backplane path to the front supplies.

The rear panel, rack backplane and front RPS6U modules divide the power route into input termination, feed distribution and regulated voltage conversion.

1. 01

   External source to rear panel

   Facility AC enters RPS6U 200-582-916-034 through two filtered and fused branches, while facility DC enters RPS6U 200-582-993-022 through two separate DC branches. These inputs remain distinct before reaching the rack.

2. 02

   Rear panel to front supplies

   Each path from RPS6U 200-582-916-034 / RPS6U 200-582-993-022 crosses the backplane connection to the matching front RPS6U position. The rear panel routes input power but does not generate the regulated card supplies.

3. 03

   Front supplies to card rails

   The front RPS6U modules convert the routed inputs into +5 VDC and ±12 VDC, then return those rails to the rack backplane. This separates a rear-input fault from a converter fault or a downstream rack-card load.
