Direct AC Input Connections to 588705000 List 31 and 588705500 List 03 Module Mounting Assemblies
Spec. No. 588705000 List 31 and 588705500 List 03 module mounting assembly contains AC input terminal
blocks which provide a separate single phase AC input connection for each rectifier position.
Circular openings are provided in the side panels (side feed) and rear covers (rear feed) of the module
mounting assembly for AC input and equipment-grounding conductors. The openings accept 3/4 inch conduit
fittings. AC input wiring should 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!
One ground conductor per conduit required.
Procedure
Refer to Figure 46 as these procedures are performed.
NOTE!
Repeat the following procedures for each module mounting assembly in the power system.
Accessing Connections and Routing Wire
1. Remove the two AC input access covers from the rear of the module mounting assembly by first
removing the screws that secure them.
2. Install conduit fittings in the side or rear openings as required. Plug buttons are provided, and must be
installed in the openings not being used.
3. Route wiring into the shelf through the previously installed conduit fittings.
Making AC Input Connections
NOTE!
In each shelf, module mounting positions are number 1-6 from left to right as viewed from the
front.
1. Make AC input connections as shown in Figure 46. Connect each wire by inserting the stripped end
into the wire opening, and then tightening the screw. Torque connections to value shown in Figure 46.
Making Equipment Grounding Connections
NOTE!
Make equipment grounding connections to earth ground,
not
to the branch circuit neutral
conductor.
1. 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 Figure 46.
Reinstalling Covers
1. After all AC input and equipment grounding connections have been made and checked, reinstall the two
AC input access covers on the back of the shelf. Secure with the previously removed screws.
