RTN)
The hot and return buses on the quad-bus configuration each
exist without interconnection jumpers, thus hot/return input cables
are to be installed on all four hot/return input connections for this
configuration (see Figure 14). 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 all four hot input positions
(see Figure 8 on Page 9)
.
Step 3.
Install the return input cables/lugs to all four return input
positions (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.

The hot buses on the quad-bus configuration each exist without
interconnection jumpers, thus hot input cables are to be installed on
all four hot input connections for this configuration (see Figure 15).
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 5).
Step 2.
Install the external return input connections.
Step 3.
Install the hot input cables/lugs to all four hot input positions
(see Figure 8 on Page 5)
.
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.
