Internal RTN)
Internal RTN)
The hot and return buses on the single-bus configuration are
all equipped with interconnection jumpers, thus hot/return

1 on this configuration (see Figure 10). For more detailed
information, refer to Appendix B and C for input bus and cable
layout.
Step 1.
Remove the input bus plastic safety covers (see Figure
5 on Page 9).
Step 2.
Install the hot input cables/lugs to hot input position 1
(see Figure 8 on Page 9).
Step 3.
Install the return input cables/lugs to return input
position 1 (see Figure 9 on Page 9).
Step 4.
Bolt all lugs to the bus bars using a flat and lock washer.
Tighten all of the hardware and ensure that the lugs are
straight and parallel with each other as they mount to
the bus bars.
Step 5.
Reattach the input bus plastic safety covers.

Step 1.
Remove the input bus plastic safety covers (see Figure
5 on Page 9).
Step 2.
Install the external return input connections.
Step 3.
