DANGER! Adhere to the "Important Safety Instructions" starting on page vii.

5.7.1 Wiring Considerations

For wire size, branch circuit protection, crimp lug, and general wiring recommendations; refer to System Application Guide
SAG582137100 and Power Data Sheet PD588705300.
5.7.2 To 19" or 23" Rectifier AC Input / Solar Converter DC Input Panel (List 40, 45) and
23" Rectifier AC Input Panel (List 46)
The Rectifier AC Input / Solar Converter DC Input Panel or Rectifier AC Input Panel provides circular openings at the sides for rectifier
AC input and grounding conductors. The openings accept 1.25 inch conduit fittings. It is recommended that AC input wiring be
provided to all rectifier mounting positions, including currently unused positions. This wiring will ease future installation of rectifiers to
meet increased load requirements.
NOTE!
A grounding conductor must be provided with each conduit.
Refer to Figure 5.3, Figure 5.4, and Figure 5.5 for connection details and recommended torque.
Procedure
1. Remove the rear cover.
2. Install conduit fittings as required in the sides of the Rectifier AC Input / Solar Converter DC Input Panel or Rectifier AC Input
Panel. Plug buttons are provided and must be installed in the openings not being used.
3. Route wiring into the Rectifier AC Input / Solar Converter DC Input Panel or Rectifier AC Input Panel through the previously
installed conduit fittings.
4. Make input connections as shown in Figure 5.3, Figure 5.4, and Figure 5.5. Connect each wire by inserting the stripped end
into the wire opening, and then tightening the screw. Torque connections to value shown in the appropriate illustration.
NOTE!
Terminal blocks for a system with maximum possible rectifier and/or solar converter modules shown. Your system
may have less terminal blocks then shown.
NOTE!
Make equipment grounding connections to earth ground,
5. Connect equipment grounding leads to the frame ground studs using installer-provided ring lugs and factory-supplied
mounting hardware. Torque connections to value shown in the appropriate illustration.
6. After all input and equipment grounding connections have been made and checked, reinstall the rear cover.
7. Locate the module position identification label either on the inside of the distribution cabinet door (rack mounted systems) or
inside the OSP cabinet when no door is furnished. As the system is being wired for module inputs, write the type of module
to be placed in each module mounting position in the space provided on the label. Write R for rectifier, C for converter, and S
for solar converter. See Figure 5.6.
