Converting Top - Feed to Bottom - Feed
The following steps describe how to convert a top - feed cabinet to a bottom - feed cabinet. Reverse
this procedure to convert a bottom - feed to a top - feed cabinet.
1. Disconnect wires from the shunts on the load shunt assembly. Note the wire colors and
location. These same colors are used when moving the shunts from panel position 1 to panel
5 position and panel position 2 to panel position 6. The solid color (blue or slate) is closest to
the input cables.
2. Disconnect the hardware securing the shunt assembly at the top of the cabinet.
Remove 6 - 32 screw securing shunt wires to the charge bus bar at the bottom of the cabinet where
the shunt assembly will be placed.
1. Relocate load shunt assembly and mount it in the bottom of the cabinet.
2. Connect shunt wires in same location and color as in previous location.
3. Connect shunt wires to the charge bus bar at the top of the cabinet where the shunt assembly
was removed using same 6 - 32 screw.
4. Move the internal return bus bar from the top to the bottom of the cabinet. Note: Internal
return bus bars may not be present.
5. The VIM1 meter needs to be reconfigured. Navigate to Menu ▶ Load Parameters ▶ First Load
and change Load Bus A location from upper - left to lower - left or lower - right depending on
which side you want to be side A and side B.
6. Relabeling might also be required as discussed in the Panel Positions and Labeling section.
