4.4.3 4.4.3 Quad-Bus Input Connections (with Internal Quad-Bus Input Connections (with Internal
RTN)RTN)
The hot and return buses on the quad-bus conguration are
equipped with interconnection jumpers between hot/return positions
1-4 and positions 5-8, thus hot/return input cables are to be
installed only on hot/return positions 1-2 and positions 5-6 on this
conguration (see Figure 12). 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 positions 1-2 and
5-6 (see Figure 8 on Page 9).
Step 3. Install the return input cables/lugs to return input positions 1-2
and 5-6 (see Figure 9 on Page 9).
Step 4. Bolt all lugs to the bus bars using a at 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 2. Install the external return input connections.
Step 3. Install the hot input cables/lugs to hot input positions 1-2 and
5-6 (see Figure 8 on Page 9).
